OBJECTIVE: There is striking paucity in consensus on the terminology, definition, and diagnostic criteria of mycotic aortic aneurysms. This literature study aims to elucidate this scientific omission, discuss its consequences, and present a proposition for reporting items on this disease.

METHODS: A systematic literature review on PubMed and Medline using mycotic and infected aortic aneurysms between 1850 and 2017 was performed. Articles were assessed according to a protocol regarding terminology, definition, and diagnostic criteria. Case series with less than 5 patients were excluded.

RESULTS: A total of 49 articles were included. The most prevalent term was mycotic aortic aneurysm but there was no widely accepted definition. Most modern publications used a diagnostic workup based on a combination on clinical presentation, laboratory results, imaging findings, and intraoperative findings. How these protean variables should be balanced was unclear. A proposition of reporting items was framed and consisted of definition of disease used, basis of diagnostic workup, exclusion criteria, patient characteristics, laboratory and imaging findings, aneurysm anatomy, details on treatment, pre/postoperative antibiotic treatment, and details on follow-up.

CONCLUSIONS: This article emphasizes the need to standardize definition, terminology, and diagnostic criteria for mycotic aortic aneurysms and proposes reporting items enhancing comparability between studies.

Abstract [en]

Treatment of mycotic aortic aneurysms (MAAs) composes a particularly difficult challenge. Open repair has been considered the gold standard, despite lack of evidence supporting its superiority compared with the emerging alternative endovascular aortic repair (EVAR). This review discusses the pros and cons of EVAR for MAAs by dissecting the three largest publications on MAAs, and concludes that there has been a paradigm shift in treatment of MAAs for the benefit of EVAR.

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.

Abstract [en]

Aortic infections are rare, life-threatening and constitute a major challenge in surgical management. This thesis aims to evaluate short – and long-term outcome of endovascular aortic repair (EVAR) for mycotic aortic aneurysms (MAA) and the subsequent risk of recurrent infections, changes in surgical practice over time for abdominal MAAs in Sweden and outcome for different treatment modalities, as well as the risk of secondary vascular infection after treatment with Open abdomen after aortic surgery.

Paper I, a retrospective single centre study of patients with MAA treated with EVAR, demonstrated a good short-term outcome, 91% survival at 30-days, and acceptable mid-term survival, 73% at 1-year.

Paper II, a retrospective international multicentre study of patients treated with EVAR for MAA, confirmed the results in paper I, and showed that EVAR is feasible and for most MAA patients a durable treatment option, 5-year survival was 55% and 10-year 41%. A total of 19% died from an infection-related complication, mostly during the first postoperative year. Non-Salmonella-positive culture was a predictor for late infection–related death.

Paper III, a population-based cohort study on all abdominal MAAs operated on between 1994-2014 in Sweden. Overall survival was 86% at 3-months, 79% at 1-year and 59% at 5-years. The survival was significantly better after endovascular compared to open repair up to 1-year without increasing recurrence of infection or reoperation, thereafter there was no difference. After 2001 EVAR constituted 60 % of all repairs, thus indicating a paradigm shift in treatment for abdominal MAAs in Sweden.

Paper IV, a prospective multicentre study of patients treated with open abdomen after aortic surgery. Infectious complications, such as graft infections, occurred after intestinal ischaemia and prolonged OA-treatment, and were often fatal.

Abstract [en]

BACKGROUND: -No reliable comparative data exist between open repair (OR) and endovascular repair (EVAR) for mycotic abdominal aortic aneurysms (MAAAs). This nationwide study assessed outcomes after OR and EVAR for MAAA in a population-based cohort.

METHODS: -All patients treated for MAAAs in Sweden between1994-2014 were identified in the Swedish vascular registry. The primary aim was to assess survival after MAAA with OR and EVAR. Secondary aims were analyses of the rate of recurrent infections and reoperations, and time-trends in surgical treatment. Survival was analyzed using Kaplan-Meier and log-rank test. A propensity score weighted correction for risk factor differences in the two groups was performed, including the operation year to account for differences in treatment and outcomes over time.

RESULTS: -132 patients were identified, (0.6% of all operated AAA in Sweden). Mean age was 70 years (SD 9.2), and 50 presented with rupture. Survival at 3-months was 86% (95% CI 80-92%), 1-year 79% (72-86%), and 5-years 59% (50-68%). The preferred operative technique shifted from OR to EVAR after 2001 (proportion EVAR 1994-2000 0%, 2001-2007 58%, 2008-2014 60%). Open repair was performed in 62 patients (47%); aortic resection and extra-anatomical bypass (n=7), in-situ reconstruction (n=50), patch plasty (n=3), and 2 patients died intraoperatively. EVAR was performed in 70 patients (53%); standard EVAR (n=55), fenestrated/branched EVAR (n=8), and visceral deviation with stent grafting (n=7); no deaths occurred intraoperatively. Survival at 3-months was lower for OR compared with EVAR (74% vs 96%, p<0.001), with a similar trend present at 1-year (73% vs 84%, p=0.054). A propensity score weighted risk-adjusted analysis confirmed the early better survival associated with EVAR. During median follow-up of 36 and 41 months for OR and EVAR, respectively, there was no difference in long-term survival (5-years 60 vs 58%, p=0.771), infection-related complications (18 vs 24%, p=0.439), or reoperation (21% vs 24%, p=0.650).

CONCLUSIONS: -This study demonstrates a paradigm shift in treatment of MAAA in Sweden, with EVAR being the preferred treatment modality. EVAR was associated with improved short-term survival compared with OR, without higher associated incidence of serious infection-related complications or reoperations.

Abstract [en]

Background-Mycotic aortic aneurysm (MAA) is a rare and life-threatening disease. The aim of this European multicenter collaboration was to study the durability of endovascular aortic repair (EVAR) of MAA, by assessing late infection-related complications and long-term survival. Methods and Results-All EVAR treated MAAs, between 1999 and 2013 at 16 European centers, were retrospectively reviewed. One hundred twenty-three patients with 130 MAAs were identified. Mean age was 69 years (range 39-86), 87 (71%) were men, 58 (47%) had immunodeficiency, and 47 (38%) presented with rupture. Anatomic locations were ascending/arch (n=4), descending (n=34), paravisceral (n=15), infrarenal aorta (n=63), and multiple (n=7). Treatments were thoracic EVAR (n=43), fenestrated/branched EVAR (n=9), and infrarenal EVAR (n=71). Antibiotic was administered for mean 30 weeks. Mean follow-up was 35 months (range 1 week to 149 months). Six patients (5%) were converted to open repair during follow-up. Survival was 91% (95% confidence interval, 86% to 96%), 75% (67% to 83%), 55% (44% to 66%), and 41% (28% to 54%) after 1, 12, 60, and 120 months, respectively. Infection-related death occurred in 23 patients (19%), 9 after discontinuation of antibiotic treatment. A Cox regression analysis demonstrated non-Salmonella-positive culture as predictors for late infection-related death. Conclusions-Endovascular treatment of MAA is feasible and for most patients a durable treatment option. Late infections do occur, are often lethal, and warrant long-term antibiotic treatment and follow-up. Patients with non-Salmonellapositive blood cultures were more likely to die from late infection.

Abstract [en]

This report presents a case of secondary aortoenteric fistula after endovascular aortic repair in a fragile patient: The fistula developed due to aneurysm shrinkage and remodeling of the stent graft, resulting in a kink eroding through the aneurysm wall into the duodenum. The aortoenteric fistula was successfully treated with a hybrid procedure with endovascular aortic repair, followed by open enteroraphy and omental flap coverage of the stent graft and local antibiotic irrigation. Despite the presence of the stent graft in a previously infected field, the patient has recovered from the acute event with no septic recurrence or hemorrhage during four years of follow-up.

Abstract [en]

OBJECTIVES:

Open abdomen (OA) treatment is sometimes necessary after surgery for aortic aneurysm (AA), to prevent or treat abdominal compartment syndrome (ACS). A multicentre study evaluating vacuum-assisted wound closure (100-150 mmHg) and mesh-mediated fascial traction (VAWCM) was performed.

METHODS:

All patients treated with OA after AA repair (2006-2009) were prospectively registered at four centres; those treated <5 days were excluded. All surviving patients underwent a 1-year follow-up, including computed tomography (CT) examination.

RESULTS:

Among 1041 patients treated with open or endovascular repair of AA, 28 (2.9%) had OA treatment with VAWCM; another two had VAWCM after hybrid operations for thoraco-abdominal AA. Eighteen (60%) were operated on for rupture and 12 (40%) electively. Eight had suprarenal or thoraco-abdominal aneurysms. Eight (27%) died within 30 days, none due to OA-related complications. Four died before abdominal closure; primary delayed fascial closure was achieved in all survivors. One-year mortality was 50%. Ten (33%) had bowel ischaemia requiring bowel resection. Late potential OA-related infectious complications occurred in five (17%), all of whom first developed intestinal ischaemia: entero-atmospheric fistulae (two), graft infections (two), aorto-enteric fistula (one). One year follow-up with clinical evaluation and CT showed no signs of graft infection. Incisional hernias occurred in 9 of 15 patients (60%); only three were symptomatic.

CONCLUSION:

VAWCM provided high fascial closure rate after AA repair and long-term OA treatment. Infectious complications occur after intestinal ischaemia and prolonged OA treatment, and are often fatal. The poor prognosis among patients needing OA after AA surgery may be improved by using VAWCM, permitting earlier closure.

PURPOSE: We report our single-center experience of early and midterm outcome after endovascular repair of mycotic aortic aneurysms (MAA). METHODS: Case records were retrospectively reviewed of 11 patients who underwent endovascular repair of 13 MAAs between 2000 and 2007. The aneurysms were localized in the aortic arch in 1 patient, descending thoracic aorta in 4, suprarenal abdominal aorta in 3, and infrarenal abdominal aorta in 5. RESULTS: Mean follow-up was 27 months. A bleeding aortoesophageal fistula resulted in one in-hospital death <or=30 days. Three patients died later: one each of sepsis, stent migration that caused intestinal ischemia, and an unknown cause. Two patients had recurrent sepsis postoperatively but no vascular complications, two had elevated inflammatory markers during follow-up but were asymptomatic, and three patients had an uneventful follow-up. CONCLUSIONS: Endovascular treatment for MAA was feasible, with acceptable perioperative mortality and midterm outcome in this single-center case series. Recurrent sepsis and late relapse with a second MAA occurred, indicating the need of long-term antibiotic therapy and follow-up, as well as the possible need for secondary open repair in selected cases. Further research is warranted to evaluate long-term outcome.
