    Multicentre prospective study of fascial closure rate after open abdomen with vacuum and mesh-mediated fascial traction2011In: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 98, no 5, p. 735-743Article in journal (Refereed)
    Abstract [en]

    Background: Damage control surgery and temporary open abdomen (OA) have been adopted widely, in both trauma and non-trauma situations. Several techniques for temporary abdominal closure have been developed. The main objective of this study was to evaluate the fascial closure rate in patients after vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) for long-term OA treatment, and to describe complications. Methods: This prospective study included all patients who received VAWCM treatment between 2006 and 2009 at four hospitals. Patients with anticipated OA treatment for fewer than 5 days and those with non-midline incisions were excluded. Results: Among 151 patients treated with an OA, 111 received VAWCM treatment. Median age was 68 years. Median OA treatment time was 14 days. Main disease aetiologies were vascular (45 patients), visceral surgical disease (57) and trauma (9). The fascial closure rate was 76.6 per cent in intention-to-treat analysis and 89 per cent in per-protocol analysis. Eight patients developed an intestinal fistula, of whom seven had intestinal ischaemia. Intestinal fistula was an independent factor associated with failure of fascial closure (odds ratio (OR) 8.55, 95 per cent confidence interval 1.47 to 49.72; P = 0.017). The in-hospital mortality rate was 29.7 per cent. Age (OR 1.21, 1.02 to 1.43; P = 0.027) and failure of fascial closure (OR 44.50, 1.13 to 1748.52; P = 0.043) were independently associated with in-hospital mortality. Conclusion: The VAWCM method provided a high fascial closure rate after long-term treatment of OA. Technique-related complications were few. No patient was left with a large planned ventral hernia.

    Modern treatment of acute mesenteric ischaemia2014In: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 101, no 1, p. E100-E108Article, review/survey (Refereed)
    Abstract [en]

    Background: Diagnosis of acute mesenteric ischaemia in the early stages is now possible with modern computed tomography (CT), using intravenous contrast enhancement and imaging in the arterial and/or portal venous phase. The availability of CT around the clock means that more patients with acute mesenteric ischaemia may be treated with urgent intestinal revascularization.

    Methods: This was a review of modern treatment strategies for acute mesenteric ischaemia.

    Results: Endovascular therapy has become an important alternative, especially in patients with acute thrombotic superior mesenteric artery (SMA) occlusion, where the occlusive lesion can be recanalized either antegradely from the femoral or brachial artery, or retrogradely from an exposed SMA after laparotomy, and stented. Aspiration embolectomy, thrombolysis and open surgical embolectomy, followed by on-table angiography, are the treatment options for embolic SMA occlusion. Endovascular therapy may be an option in the few patients with mesenteric venous thrombosis who do not respond to anticoagulation therapy. Laparotomy is needed to evaluate the extent and severity of visceral organ ischaemia, which is treated according to the principles of damage control surgery.

    Conclusion: Modern treatment of acute mesenteric ischaemia involves a specialized approach that considers surgical and, increasingly, endovascular options for best outcomes. Endovascular increasingly important

    Negative-pressure wound therapy for prevention and treatment of surgical-site infections after vascular surgery2017In: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 104, no 2, p. E75-E84Article, review/survey (Refereed)
    Abstract [en]

    BackgroundIndications for negative-pressure wound therapy (NPWT) in vascular surgical patients are expanding. The aim of this review was to outline the evidence for NPWT on open and closed wounds. MethodsA PubMed, EMBASE and Cochrane Library search from 2007 to June 2016 was performed combining the medical subject headings terms wound infection', abdominal aortic aneurysm (AAA)', fasciotomy', vascular surgery' and NPWT' or VAC'. ResultsNPWT of open infected groin wounds was associated with shorter duration of wound healing by 47 days, and was more cost-effective than alginate dressings in one RCT. In one RCT and six observational studies, NPWT-related major bleeding and graft preservation rates were 0-10 and 83-100 per cent respectively. One retrospective comparative study showed greater wound size reduction per day, fewer dressing changes, quicker wound closure and shorter hospital stay with NPWT compared with gauze dressings for lower leg fasciotomy. NPWT and mesh-mediated fascial traction after AAA repair and open abdomen was associated with high primary fascial closure rates (96-100 per cent) and low risk of graft infection (0-7 per cent). One retrospective comparative study showed a significant reduction in surgical-site infection, from 30 per cent with standard wound care to 6 per cent with closed incisional NPWT. ConclusionNPWT has a central role in open and infected wounds after vascular surgery; the results of prophylactic care of closed incisions are promising.

    Temporary Abdominal Closure After Abdominal Aortic Aneurysm Repair: A Systematic Review of Contemporary Observational Studies2016In: European Journal of Vascular and Endovascular Surgery, ISSN 1078-5884, E-ISSN 1532-2165, Vol. 51, no 3, p. 371-378Article, review/survey (Refereed)
    Abstract [en]

    Objectives: The aim of this paper was to review the literature on temporary abdominal closure (TAC) after abdominal aortic aneurysm (AAA) repair. Methods: This was a systematic review of observational studies. A PubMed, EM BASE and Cochrane search from 2007 to July 2015 was performed combining the Medical Subject Headings "aortic aneurysm" and "temporary abdominal closure", "delayed abdominal closure", "open abdomen", "abdominal compartment syndrome", "negative pressure wound therapy", or "vacuum assisted wound closure". Results: Seven original studies were found. The methods used for TAC were the vacuum pack system with (n = 1) or without (n = 2) mesh bridge, vacuum assisted wound closure (VAWC; n = 1) and the VAWC with mesh mediated fascial traction (VACM; n = 3). The number of patients included varied from four to 30. Three studies were exclusively after open repair, one after endovascular aneurysm repair, and three were mixed series. The frequency of ruptured AAA varied from 60% to 100%. The primary fascia] closure rate varied from 79% to 100%. The median time to closure of the open abdomen was 10.5 and 17 days in two prospective studies with a fascia] closure rate of 100% and 96%, respectively; the inclusion criterion was an anticipated open abdomen therapy time >= 5 days using the VACM method. The graft infection rate was 0% in three studies. No patient with longterm open abdomen therapy with the VACM in the three studies was left with a planned ventral hernia. The in hospital survival rate varied from 46% to 80%. Conclusions: A high fascial closure rate without planned ventral hernia is possible to achieve with VACM, even after long-term open abdomen therapy. There are, however, few publications reporting specific results of open abdomen treatment after AAA repair, and there is a need for randomized controlled trials to determine the most efficient and safe TAC method during open abdomen treatment after AAA repair.

    Vacuum-assisted wound closure and mesh-mediated fascial traction for open abdomen therapy: a systematic review2017In: Anaesthesiology intensive therapy, ISSN 1731-2515, Vol. 49, no 2, p. 139-145Article, review/survey (Refereed)
    Abstract [en]

    BACKGROUND: The aim of this paper was to review the literature on vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) in open abdomen therapy. It was designed as systematic review of observational studies.

    METHODS: A Pub Med, EMBASE and Cochrane search from 2007/01-2016/07 was performed combining the Medical Subject Headings "vacuum", "mesh-mediated fascial traction", "temporary abdominal closure", "delayed abdominal closure", "open abdomen", "abdominal compartment syndrome", "negative pressure wound therapy" or "vacuum assisted wound closure".

    RESULTS: Eleven original studies were found including patients numbering from 7 to 111. Six studies were prospective and five were retrospective. Nine studies were on mixed surgical (n = 9), vascular (n = 6) and trauma (n = 6) patients, while two were exclusively on vascular patients. The primary fascial closure rate per protocol varied from 80-100%. The time to closure of the open abdomen varied between 9-32 days. The entero-atmospheric fistula rate varied from 0-10.0%. The in-hospital survival rate varied from 57-100%. In the largest prospective study, the incisional hernia rate among survivors at 63 months of median follow-up was 54% (27/50), and 16 (33%) repairs out of 48 incisional hernias were performed throughout the study period. The study patients reported lower short form health survey (SF-36) scores than the mean reference population, mainly dependent on the prevalence of major co-morbidities. There was no difference in SF-36 scores or a modified ventral hernia pain questionnaire (VHPQ) at 5 years of follow up between those with versus those without incisional hernias.

    CONCLUSIONS: A high primary fascial closure rate can be achieved with the vacuum-assisted wound closure and meshmediated fascial traction technique in elderly, mainly non-trauma patients, in need of prolonged open abdomen therapy.

    Diagnostic pitfalls at admission in patients with acute superior mesenteric artery occlusion2012In: Journal of Emergency Medicine, ISSN 0736-4679, E-ISSN 1090-1280, Vol. 42, no 6, p. 635-641Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:

    Acute superior mesenteric artery (SMA) occlusion leads to acute intestinal ischemia and is associated with high mortality. Early diagnosis is often missed, and confounding factors leading to diagnostic delays need to be highlighted.

    OBJECTIVES:

    To identify potential diagnostic laboratory pitfalls at admission in patients with acute SMA occlusion.

    METHODS:

    Fifty-five patients with acute SMA occlusion were identified from the in-hospital register during a 4-year period, 2005-2009.

    RESULTS:

    The median age was 76 years; 78% were women. The occlusion was embolic in 53% and thrombotic in 47% of patients. At admission, troponin I was above the clinical decision level (> 0.06 μg/L) for acute ischemic myocardial injury in 9/19 (47%) patients with embolic occlusion. Elevated pancreas amylase and normal plasma lactate were found in 12/45 and 13/27, respectively. A troponin I (TnI) above the clinical decision level was associated with a high frequency of referrals from the general surgeon to a specialist in internal medicine (p = 0.011) or a cardiologist (p = 0.024). The diagnosis was established after computed tomography angiography in 98% of the patients. The overall in-hospital mortality rate was 33%. Attempting intestinal revascularization (n = 43; p < 0.001), with a 95% frequency rate of completion control of the vascular procedure, was associated with a higher survival rate, whereas referral to the cardiologist was associated with a higher mortality rate (p = 0.018).

    CONCLUSION:

    Elevated TnI was common in acute SMA occlusion, and referral to the cardiologist was found to be associated with adverse outcome. Elevated pancreas amylase and normal plasma lactate values are also potential pitfalls at admission in patients with acute SMA occlusion.

    Open Abdomen Therapy with Vacuum and Mesh Mediated Fascial Traction After Aortic Repair: an International Multicentre Study2017In: European Journal of Vascular and Endovascular Surgery, ISSN 1078-5884, E-ISSN 1532-2165, Vol. 54, no 6, p. 697-705Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES:

    Open abdomen therapy may be necessary to prevent or treat abdominal compartment syndrome (ACS). The aim of the study was to analyse the primary delayed fascial closure (PDFC) rate and complications after open abdomen therapy with vacuum and mesh mediated fascial traction (VACM) after aortic repair and to compare outcomes between those treated with open abdomen after primary versus secondary operation.

    METHODS:

    This was a retrospective cohort, multicentre study in Sweden, Finland, and Norway, including consecutive patients treated with open abdomen and VACM after aortic repair at six vascular centres in 2006-2015. The primary endpoint was PDFC rate.

    RESULTS:

    Among 191 patients, 155 were men. The median age was 71 years (IQR 66-76). Ruptured abdominal aortic aneurysm (RAAA) occurred in 69.1%. Endovascular/hybrid and open repairs were performed in 49 and 142 patients, respectively. The indications for open abdomen were inability to close the abdomen (62%) at primary operation and ACS (80%) at secondary operation. Duration of open abdomen was 11 days (IQR 7-16) in 157 patients alive at open abdomen termination. The PDFC rate was 91.8%. Open abdomen initiated at primary (N=103), compared with secondary operation (N=88), was associated with less severe initial open abdomen status (p=.006), less intestinal ischaemia (p=.002), shorter duration of open abdomen (p=.007), and less renal replacement therapy (RRT, p<.001). In hospital mortality was 39.3%, and after entero-atmospheric fistula (N=9) was 88.9%. Seven developed graft infection within 6 months, 1 year mortality was 28.6%. Intestinal ischaemia (OR 3.71, 95% CI 1.55-8.91), RRT (OR 3.62, 95% CI 1.72-7.65), and age (OR 1.12, 95% CI 1.06-1.12), were independent factors associated with in hospital mortality, but not open abdomen initiated at primary versus secondary operation.

    CONCLUSIONS:

    VACM was associated with a high PDFC rate after prolonged open abdomen therapy following aortic repair. Patient outcomes seemed better when open abdomen was initiated at primary, compared with secondary operation but a selection effect is possible.

    Fatal colonic ischaemia: A population-based study2006In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 41, no 11, p. 1312-1319Article in journal (Refereed)
    Abstract [en]

    Objectives. To estimate the incidence of fatal colonic ischaemia (CI) and the cause-specific mortality of CI, and to describe the localization and extension of colonic infarction and quantify the risk factors associated with CI. Material and methods. Between 1970 and 1982 the autopsy rate in Malmo, Sweden, was 87%, creating the possibilities for a population-based study. Out of 23,446 clinical autopsies, 997 cases were coded for intestinal ischaemia in a database. In addition, 7569 forensic autopsy protocols were analysed. In a case-control study nested in the clinical autopsy cohort, four CI-free controls, matched for gender, age at death and year of death, were identified for each fatal CI case in order to evaluate the risk factors. Results. The cause-specific mortality ratio was 1.7/1000 autopsies. The overall incidence of autopsy-verified fatal CI was 1.7/100,000 person years, increasing with age up to 23/100,000 person years in octogenarians. Fatal cardiac failure (odds ratio (OR) 5.2), fatal valvular disease (OR 4.3), previous stroke (OR 2.5) and recent surgery (OR 3.4) were risk factors for fatal CI. Narrowing/occlusion of the inferior mesenteric artery (IMA) at the aortic origin was present in 68% of the patients. The most common segments affected by transmural infarctions were the sigmoid (83%) and the descending (77%) colon. Conclusions. Heart failure, atherosclerotic occlusion/stenoses of the IMA and recent surgery were the main risk factors causing colonic hypoperfusion and infarction. Segments of transmural infarctions were observed within the left colon in 94% of the patients. Awareness of the diagnosis and its associated cardiac comorbidities might help to improve survival.

    Follow-up after endovascular aortic aneurysm repair can be stratified based on first postoperative imaging2018In: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 05, no 6, p. 709-718Article in journal (Refereed)
    Abstract [en]

    Background

    Lifelong postoperative surveillance is recommended following endovascular aneurysm repair (EVAR). Although the purpose is to prevent and/or identify complications early, it also results in increased cost and workload. This study was designed to examine whether it may be possible to identify patients at low risk of complications based on their first postoperative CT angiogram (CTA).

    Methods

    All patients undergoing EVAR in two Swedish centres between 2001 and 2012 were identified retrospectively and categorized based on the first postoperative CTA as at low risk (proximal and distal sealing zone at least 10 mm and no endoleak) or high risk (sealing zone less than 10 mm and/or presence of any endoleak) of complications.

    Results

    Some 326 patients (273 men) with a CTA performed less than 1 year after EVAR were included (low risk 212, 65·0 per cent; high risk 114, 35·0 per cent). There was no difference between the groups in terms of sex, age, co‐morbidities, abdominal aortic aneurysm (AAA) diameter, preoperative AAA neck anatomy, stent‐graft type or duration of follow‐up (mean(s.d.) 4·8(3·2) years). Five‐year freedom from AAA‐related adverse events was 97·1 and 47·7 per cent in the low‐ and high‐risk groups respectively (P < 0·001). The corresponding freedom from AAA‐related reintervention was 96·2 and 54·1 per cent (P < 0·001). The method had a sensitivity of 88·3 per cent, specificity of 77·0 per cent and negative predictive value of 96·6 per cent to detect AAA‐related adverse events. The number of surveillance imaging per AAA‐related adverse event was 168 versus 11 for the low‐risk versus high‐risk group.

    Conclusion

    Two‐thirds of patients undergoing EVAR have an adequate seal and no endoleak on the first postoperative CTA, and a very low risk of AAA‐related events up to 5 years. Less vigilant follow‐up after EVAR may be considered for these patients.

    The role of hybrid procedures in the management of peripheral vascular disease2012In: Scandinavian Journal of Surgery, ISSN 1457-4969, E-ISSN 1799-7267, Vol. 101, no 4, p. 232-237Article, review/survey (Refereed)
    Abstract [en]

    This paper provides a summary of up-to-date information and experience with the combined treatment of patients suffering from peripheral arterial disease (PAD) with endovascular and open surgery, performed simultaneously and in a single operating room. Hybrid intervention is reported to have good results in well-indicated groups of patients with acute and chronic limb ischemia, even with older, high-risk patients. The indications for the use of this technique remain unclear with inconsistent opinions among vascular surgeons. The indications for treat-ment were divided into three main groups: 1) Patients with chronic limb ischemia, 2) acute limb ischemia, and 3) occlusion of a previous vascular reconstruction. The operating techniques for the most commonly used combinations are described. In conclusion, hybrid operating techniques are often useful when treating complex problems and multilevel disease in patients with chronic or acute lower limb ischemia. Modern vascular surgeons need to master both open and endovascular techniques, and to combine them in a creative fashion to the benefit of our patients.

    True aneurysm in autologous hemodialysis fistulae: definitions, classification and indications for treatment2015In: Journal of Vascular Access, ISSN 1129-7298, E-ISSN 1724-6032, Vol. 16, no 6, p. 446-453Article, review/survey (Refereed)
    Abstract [en]

    INTRODUCTION: Definition, etiology, classification and indication for treatment of the arteriovenous access (AVA) aneurysm are poorly described in medical literature. The objectives of the paper are to complete this information gap according to the extensive review of the literature.

    METHODS: A literature search was performed of the articles published between April 1, 1967, and March 1, 2014. The databases searched included Medline and the Cochrane Database of Systematic Reviews. The eligibility criteria in this review studies the need to assess the association of aneurysms and pseudoaneurysms with autologous AVA. Aneurysms and pseudoaneurysms involving prosthetic AVA were not included in this literature review. From a total of 327 papers, 54 non-English papers, 40 case reports and 167 papers which did not meet the eligibility criteria were removed. The remaining 66 papers were reviewed.

    RESULTS: Based on the literature the indication for the treatment of an AVA aneurysm is its clinical presentation related to the patient's discomfort, bleeding prevention and inadequate access flow. A new classification system of AVA aneurysm, which divides it into the four types, was also suggested.

    CONCLUSIONS: AVA aneurysm is characterized by an enlargement of all three vessel layers with a diameter of more than 18 mm and can be presented in four types according to the presence of stenosis and/or thrombosis. The management of an AVA aneurysm depends on several factors including skin condition, clinical symptoms, ease of cannulation and access flow. The diameter of the AVA aneurysm as a solo parameter is not an indication for the treatment.

    Early and late outcomes of hybrid endovascular and open repair procedures in patients with peripheral arterial disease2013In: VASA, ISSN 0301-1526, E-ISSN 1664-2872, Vol. 42, no 4, p. 292-300Article in journal (Refereed)
    Abstract [en]

    Background: Hybrid endovascular and open reconstructions are used increasingly often for multilevel revascularization for lower limb ischaemia. The aim was to evaluate outcomes after such procedures in a single-center non-randomized retrospective study. Patients and methods: Consecutive patients with multilevel arterial disease who underwent single session hybrid procedures were analyzed depending on the type of ischaemia and the type of revascularization. Results: 164 patients were included with a median follow up time of 14 months (range: 0 - 70). Indication was claudication (group 1, 47 %), critical limb ischaemia (group 2, 33 %) and acute limb ischaemia (group 3, 20 %). Technical success rate was 99.3%, perioperative mortality 2%. Primary, assisted-primary and secondary patency rates at one year were 60%, 61% and 64%, respectively. Primary, primary assisted and secondary patency were lower in group 2 and 3 compared to group 1 (all p < 0.05). Results were better when endovascular repairs were performed above compared to below the open repair site (all p < 0.05). Limb salvage at 1 year in groups 1 - 3 were 98%, 92% and 90%, respectively. The risk of major amputation was highest in group 3 compared to group 1 (p = 0.001) or group 2 (p < 0.04). Conclusions: The results depend on the type of ischaemia and the localization of endovascular procedures.

    Variations in abdominal aortic aneurysm care: a report from the International consortium of vascular registries2016In: Circulation, ISSN 0009-7322, E-ISSN 1524-4539Article in journal (Refereed)
    Abstract [en]

    Background: This project by the ICVR (International Consortium of Vascular Registries), a collaboration of 11 vascular surgical quality registries, was designed to evaluate international variation in the contemporary management of abdominal aortic aneurysm (AAA) with relation to recommended treatment guidelines from the Society for Vascular Surgery and the European Society for Vascular Surgery.

    Methods: Registry data for open and endovascular AAA repair (EVAR) during 2010 to 2013 were collected from 11 countries. Variations in patient selection and treatment were compared across countries and across centers within countries.

    Results: Among 51 153 patients, 86% were treated for intact AAA (iAAA) and 14% for ruptured AAA. Women constituted 18% of the entire cohort (range, 12% in Switzerland–21% in the United States; P<0.01). Intact AAAs were repaired at diameters smaller than recommended by guidelines in 31% of men (<5.5 cm; range, 6% in Iceland–41% in Germany; P<0.01) and 12% of women with iAAA (<5 cm; range, 0% in Iceland–16% in the United States; P<0.01). Overall, use of EVAR for iAAA varied from 28% in Hungary to 79% in the United States (P<0.01) and for ruptured AAA from 5% in Denmark to 52% in the United States (P<0.01). In addition to the between-country variations, significant variations were present between centers in each country in terms of EVAR use and rate of small AAA repair. Countries that more frequently treated small AAAs tended to use EVAR more frequently (trend: correlation coefficient, 0.51; P=0.14). Octogenarians made up 23% of all patients, ranging from 12% in Hungary to 29% in Australia (P<0.01). In countries with a fee-for-service reimbursement system (Australia, Germany, Switzerland, and the United States), the proportions of small AAA (33%) and octogenarians undergoing iAAA repair (25%) were higher compared with countries with a population-based reimbursement model (small AAA repair, 16%; octogenarians, 18%; P<0.01). In general, center-level variation within countries in the management of AAA was as important as variation between countries.

    Conclusions: Despite homogeneous guidelines from professional societies, significant variation exists in the management of AAA, most notably for iAAA diameter at repair, use of EVAR, and the treatment of elderly patients. ICVR provides an opportunity to study treatment variation across countries and to encourage optimal practice by sharing these results.

    Enteric fistulation after renal artery reconstruction: a systematic literature review2010In: World Journal of Surgery, ISSN 0364-2313, E-ISSN 1432-2323, Vol. 34, no 10, p. 2305-2307Article in journal (Refereed)
    Abstract [en]

    A systematic literature review has revealed 14 cases of arterioenteric fistulation after renovascular reconstruction. Among the 14 patients, 9 had thrombotic occlusion of the reconstruction and 5 underwent nephrectomy, but neither procedure prevented fistulation. There was a dominance of right-sided bypass reconstructions. All patients but one suffered from gastrointestinal bleeding; 3 died before operation and 5 had herald bleeds. Three died as a direct result of surgery. Various technical solutions were used, and the follow-up time was clearly unsatisfactory; in only 2 patients was the follow-up longer than 1 year. Arterioenteric fistulation is a serious complication, associated with a high mortality rate and a high incidence of kidney loss among survivors.

    Secondary arterioenteric fistulation: a systematic literature analysis2009In: European Journal of Vascular and Endovascular Surgery, ISSN 1078-5884, E-ISSN 1532-2165, Vol. 37, no 1, p. 31-42Article, review/survey (Refereed)
    Abstract [en]

    OBJECTIVE: To analyze the problem of secondary arterioenteric fistulation, a rare but serious complication. METHODS: A systematic literature review was performed searching for case reports as well as patients included in articles analyzing especially infectious complications. RESULTS: 332 individual cases and 1135 patients from papers on complications were identified. All types of surgery involving aorta and its branches could precede the complication, endovascular procedures included. The development of a fistula can occur at any time after primary surgery, the longest delay being 26 years. Bleeding was the dominating symptom with herald bleeding in more than half of the patients, infectious problems present in around one quarter. Diagnostic delay was typical, although decreasing over time. The mortality was high, lowest after axillobifemoral revascularization and aortic graft removal. The information in the articles is often heterogeneous and incomplete, and follow-up time is often too short. Mortality after fistulation seems to have decreased over time. CONCLUSION: Secondary arterioenteric fistula continues to be an extremely serious complication after surgery on aorta and its branches. Every effort must be made to arrive at a rapid diagnosis. The best therapeutic option seems to be axillobifemoral revascularization and subsequent graft removal, which however, requires haemodynamically stable patients. Endovascular repair may serve as a bridge to open surgery.

    Difficult-to-control intraoperative bleeding--practical measures

    Bleeding with difficulties obtaining haemostasis can be a catastrophe. This paper summarizes a symposium with the above title. A short introduction gives the background of normal haemostasis as well as iatrogenic vascular injuries as reflected in the Swedish vascular registry (Swedvasc). Practical guidelines are given on how to manage situations of severe haemorrhage with the help of pharmacological substances, local haemostatics, endovascular methodology and open surgery.

    Validation of the VASCUNET registry - pilot study2014In: VASA, ISSN 0301-1526, E-ISSN 1664-2872, Vol. 43, no 2, p. 141-144Article in journal (Refereed)
    Abstract [en]

    Background: VASCUNET is an international registry of vascular surgical (open and endovascular) procedures since 1997. The aim of this paper is to describe a pilot validation performed at three hospitals in Hungary in September 2012. Patients and methods: Three core indications were checked: abdominal aortic aneurysm, carotid artery disease and limb ischemia with infrainguinal treatment. Results: 2439 registered procedures had been reported with between 94 and 109 per cent agreement with hospital administrative numbers. In a random sample of 29 patients the VASCUNET data were compared with the patient records regarding risk factors, procedures performed and in hospital results. Only few discrepancies were found. Conclusions: The conclusions are that validation is feasible, that this pilot project in Hungary showed good agreement between registry and local patient records. For a registry to be accepted and used both for practical and scientific purposes regular validation by senior surgeons should be undertaken and the vascular surgical community must have a budget for such a process.

    Invasive treatment for renovascular disease. A twenty year experience from a population based registry2008In: Journal of Cardiovascular Surgery, ISSN 0021-9509, E-ISSN 1827-191X, Vol. 49, no 5, p. 559-563Article in journal (Refereed)
    Abstract [en]

    AIM: To analyze time trends in invasive treatment of renovascular disease in one country. METHODS: Data have been analyzed from registrations in the Swedish Vascular Registry. RESULTS: Invasive treatment for renovascular disease contributes around 1% of all vascular surgery within the Swedish Vascular Registry. Over the twenty-year period 1987-2006 the population-based frequency of invasive treatment for renovascular disease has increased; 1 597 procedures have been registered with an increase over time. The age of the treated patients has increased over the period (P<0.001). There has been a shift from open to endovascular procedure and from isolated percutaneous transluminal renal angioplasty (PTRA) to PTRA combined with a stent. Complications and mortality are significantly higher in patients undergoing open reconstruction (P<0.01). One year follow-up is incomplete and long-term results are therefore not possible to evaluate through registry-data only. CONCLUSION: Using nation-wide registry data it is possible to analyze time-trends also concerning rare diseases or interventions. The changing pattern toward endovascular treatment of renovascular disease is obvious. Follow-up data at one year are incomplete.

    Secondary aortoenteric fistula after endovascular aortic interventions: a systematic literature review2008In: Journal of Vascular and Interventional Radiology, ISSN 1051-0443, E-ISSN 1535-7732, Vol. 19, no 2, p. 163-165Article, review/survey (Refereed)
    Abstract [en]

    PURPOSE: To evaluate the collective incidence of, and experience with, aortoenteric fistula after endovascular aortoiliac therapy. MATERIALS AND METHODS: A systematic literature research was performed to identify cases of aortoenteric fistulation after aortic stent-graft procedures or stent implantation. RESULTS: The review revealed 16 cases of aortoenteric fistulation after aortic stent-grafting (n = 15) or stent placement (n = 1), in 14 patients with abdominal aortic aneurysm. Six had undergone endovascular aneurysm repair because of what was considered a "hostile abdomen." The symptoms did not differ from those in patients with arterioenteric fistulation after open aortic repair. A defect in the stent-graft or its function was the predominant cause of fistulation. One fistula was diagnosed at autopsy, two patients died perioperatively, and 13 survived with in situ repair or an axillobifemoral graft, all after removal of the stent-graft or stent. However, the follow-up time was short, longer than 1 year in only five of the 13 survivors. CONCLUSIONS: Aortoenteric fistulation does occur after endovascular implantation of stents and stent-grafts. The incidence is unknown but is probably low. Follow-up time in most publications was less than 1 year, which is considered short to assess potential graft infection.

    Abdominal aortic aneurysm and new WHO criteria for screening2013In: International Journal of Angiology, ISSN 0392-9590, E-ISSN 1827-1839, Vol. 32, no 1, p. 37-41Article, review/survey (Refereed)
    Abstract [en]

    Does screening of abdominal aortic aneurysm (AAA) fulfil the recently revised the World Health Organization WHO criteria for screening? Contemporary data from the literature are used to analyze whether the ten recent WHO criteria can be used to motivate AAA screening. Although the prevalence of AAA seems to decrease, at least screening of 65-year old males saves lives and is cost-effective. Ultrasonographic screening for AAA in risk populations fulfils the new WHO criteria for screening.

    Abdominal aortic aneurysm--to screen or not to screen2008In: European Journal of Vascular and Endovascular Surgery, ISSN 1078-5884, E-ISSN 1532-2165, Vol. 35, no 1, p. 13-18Article in journal (Refereed)
    Abstract [en]

    With the ten WHO criteria for a screening program to be started, screening for abdominal aortic aneurysm is analyzed. Most of the criteria are fulfilled concerning the 65-year old male population, whereas concerning females we need more knowledge. Still the aneurysmal diameter is the most important factor to select patients for treatment meaning that many aneurysms are treated where rupture should never have occurred. Research projects giving more information on pathophysiological processes behind expansion and rupture should have priority.
