Abstract [en]

BACKGROUND: Trauma triage based on prehospital information facilitates correct allocation of in-hospital resources. The Swedish national two-tier trauma team activation (TTA) criteria were revised in 2016. The current study aimed to evaluate the safety and efficacy of the new criteria.

METHODS: Five centres covering trauma care for 1.2 million inhabitants registered all trauma patients prospectively in the Swedish trauma registry (SweTrau) prior to and after stepwise introduction of new TTA criteria within the cohort (a prospective stepped-wedge cohort study design; period August 2016-November 2017). Evaluation of full- and limited-TTA frequency, under- and overtriage were performed at equal duration before and after this change.

RESULTS: The centres registered 1948 patients, 1882 (96.6%) of which were included in the study. With new criteria, frequency of full-TTA was unchanged, while limited-TTA decreased with 46.3% (from 988 to 531). 30-day trauma mortality was unchanged. The overtriage was 107/150 (71.3%) with former criteria, and 104/144 (72.2%) with new criteria, p = 0.866. Undertriage was 50/1037 (4.8%) versus 39/551 (7.1%), p = 0.063. Undertriage was consistently > 20% in patients with fall injury. Among patients with Injury Severity Score (ISS) > 15, 50/93 (53.8%) did not initiate full-TTA with former, vs 39/79 (49.4%) with new criteria, p = 0.565. Age > 60-years was a risk factor for undertriage (OR 2.89, p < 0.001), while low fall injuries indicated a trend (OR 2.70, p = 0.051).

CONCLUSIONS: The newly implemented Swedish TTA criteria result in a reduction in limited TTA frequency, indicating an increased efficiency in use of resources. The over- and undertriage is unchanged compared to former criteria, thus upholding patient safety.

Abstract [en]

OBJECTIVE: To evaluate trauma triage criteria in terms of compliance, undertriage, and overtriage and identify risk factors for mistriage.

METHODS: In a retrospective cohort study, all consecutive trauma patients at a University Hospital in Sweden in 2012 were included. Patients were stratified into three groups on the basis of trauma team activation (full trauma team, limited trauma team, and no trauma team). Case records were reviewed for mechanism of injury, vital signs, and injuries. Compliance with alert criteria was evaluated and injury severity score combined with the Matrix method was used for assessment of overtriage and undertriage.

RESULTS: A total of 1424 trauma patients were included in the study. Seventy-three (5.1%) patients activated a full trauma team, 732 (51.4%) a limited trauma team, and 619 (43.5%) did not activate any trauma team. Undertriage was 2.7% [95% confidence interval (CI): 1.9-3.8%] and overtriage was 34.2% (95% CI: 23.5-46.3%) in the complete cohort. Compliance with 'trauma triage criteria' was assessed by comparing actual alerts with what was estimated to be the correct alert levels on the basis of prehospital case records. Compliance with full trauma team criteria was 80% (68-88%), limited trauma team was 54% (51-58%), and no trauma team was 79% (76-82%). Assuming full compliance with trauma criteria, the Matrix method resulted in an undertriage of 2.3% (95% CI: 1.6-3.3%) and an overtriage of 42.6% (95% CI: 32.4-53.2%).

CONCLUSION: The overtriage and undertriage in this study is in line with the recommendations of the American College of Surgeons Committee on Trauma. However, better compliance with trauma alert criteria would result in fewer trauma team activations without affecting patient safety.

Abstract [en]

Fenestrated and branched endovascular aortic repair (F/B-EVAR) is associated with a high degree of technical and clinical success. Despite this, studies have also reported high reintervention rates, and these are often related to the bridging stent grafts. Often new devices appear on the market before they have been tested in the bridging stent graft position. This review aims to assess the current literature on bridging stent grafts and discuss complications, illustrated by case reports. Complications reported with bridging stem grafts include; endoleak, kink, fracture, migration, occlusion, stenosis and perforation. Some known risk factors for bridging stent occlusions are renal artery stent grafts vs. SMA and celiac artery stent grafts. Some device specific complications have also been reported such as type IIIc endoleak with the Lifestream stent graft (Bard Peripheral Vascular, Tempe, AZ, USA) fractures and type Hid endoleaks with the 1st generation of Begraft (BentleyinnoMed, Hechingen, Germany). In addition, this review also discusses some newer devices with possible relation to complications such as stenosis and target vessel perforation. In conclusion, bridging stent grafts in fenestrated and branched aortic repair have a good midterm patency. Despite this, remaining issues are often related to the bridging stent grafts. Thorough follow-up and attention are needed, especially when new devices are introduced. The endovascular community should work towards a common global feedback system.

Abstract [en]

Introduction: The use of fenestrated and branched endovascular technologies in complex aortic aneurysm repair (F/BEVAR) is increasing, with a trend toward using longer sealing zones and incorporating more target vessels. Successful aneurysm exclusion and prevention of long-term treatment failure need to be balanced against the increased complexity of more extensive procedures. The aim of this study was to analyze relationships between the number of catheterized vessels and multiple operative variables as a means for evaluating procedural complexity.

Methods: Operative data from consecutive F/BEVAR procedures performed at a single center from 2012 to 2015 were analyzed. An equal number of EVAR procedures, randomly selected, from this period were also analyzed. Only intact aneurysms were included. Complex aneurysms were grouped based on the required number of target vessel catheterization. Ten procedural variables, categorized as perioperative, postoperative, and radiologic-related, were compared. Pearson correlation analysis and regression analysis were performed. The correlation coefficients, r, were classified using Cohen boundaries, r >= 0.5 indicating a strong relationship.

Results: There were 63 EVAR, 40 FEVAR, and 22 BEVAR procedures. There was no significant difference in patient comorbidities between conventional EVAR and complex procedure groups. The complex procedures included 23 two-vessel, 20 three-vessel, and 19 four-vessel catheterizations. Strong linear relationships between the number of branch vessel catheterizations and the following variables were identified: accumulated skin dose (r = .504), contrast volume (r = .652), fluoroscopy duration (r = .598), number of angiography series (r = .650), anesthesiology duration (r = .742), procedure duration (r = .554), and total length of stay (r = .533).

Conclusion: The complexity of FEVAR and BEVAR procedures reveals strong correlations between multiple peri- and postoperative variables. These exposures and risks should be borne in mind when considering treatment of complex abdominal aortic aneurysms as well as long-term clinical outcomes.

Abstract [en]

Objective: This study aimed to determine the outcome of 65 year old men five years after carotid ultrasound screening, as well as risk factors for disease progression. Methods: All 65 year old men living in the county of Uppsala 2007-2009 were invited to an ultrasound examination of both carotid arteries and re-invited at age 70. The cohort was grouped into normal carotids, plaque without significant stenosis, moderate stenosis (50-79%), and severe stenosis (80-99%). The rate of disease progression was assessed from ultrasound data. Data on mortality, ipsilateral neurological events, risk factors, and medication were obtained from patient records and population registries. Results: Among men participating in carotid screening at age 65, 3,057 were re-screened at age 70. In those with normal carotids (n = 2,318), 23 (1.0%) progressed to a moderate stenosis, and four (0.2%) to a symptomatic severe stenosis. Among those with plaque (n = 696), 25 (3.6%) progressed to moderate stenosis, and eight (1.1%) to severe stenosis, of whom four (0.6%) had symptoms. Of 31 men with 50-79% stenosis, four (12.9%) had progressed to a severe stenosis, of whom two (6.5%) developed symptoms. Five of twelve subjects (42%) with 80-99% stenosis developed symptoms. Disease regression was present among 289/692 plaque (41.7%) and 16/33 stenosis (48.4%). In multivariable analysis, smoking, coronary artery disease and hypercholesterolemia were associated with disease progression. The proportions of antiplatelet, statin, and antihypertensive treatment in the population at age 70 were 22%, 29%, and 55%, respectively. Conclusion: Men with plaques and moderate stenosis have a good prognosis, but in those with severe stenosis there is a high risk of neurological events.

Abstract [en]

Objective: Mycotic aortic aneurysms are rare, life threatening, and complex. This nationwide study aimed to assess outcome after repair of mycotic thoracic aortic aneurysms (MTAAs).

Methods: Patients treated in Sweden for MTAAs between 2000 and 2016 were identified in the Swedish vascular registry (2010-16) and local patient registries (2000-09). Primary outcome was survival, and secondary outcomes included surgical strategy, rate of infection related complications (IRC), and re-operations.

Results: Fifty-two patients (median age 71 +/- 8.1 years; 28 [54%] men, 13 [25%] ruptured) were identified (3.6% of all thoracic aortic aneurysm repairs in Sweden). Aneurysm location was aortic arch (n = 6; 11%), descending aorta (n = 42; 81%), and multiple locations (n = 4; 8%). Twenty-nine (56%) patients had positive cultures; the most prevalent agent was Staphylococcus aureus (n = 16; 31%). Operative techniques included thoracic endovascular aortic repair (TEVAR; n = 35 [67%]), fenestrated/branched TEVAR (n = 8; 15%), hybrid repair (n = 7; 14%), and open patch repair (n = 2; 4%). Survival was 92% (95% confidence interval [CI] 88-96) at 30 days, 88% (95% CI 84-93) at three months, 78% (73-84) at one year, and 71% (64-77) at five years. The mean follow up among survivors (> 90 days) was 45 months (range 4-216 months). Antibiotics were administered for a median of 15 weeks (range 0-220 weeks). IRCs occurred in nine patients (17%): sepsis (n = 3), graft infection (n = 3), recurrent mycotic aneurysm (n = 1), aorto-oesophageal/bronchial fistula (n = 2). Six (67%) IRCs were fatal; 80% occurred within the first year. Re-operations were performed in nine patients (17%).

Conclusions: TEVAR was often used as treatment for MTAAs, with acceptable short- and long-term survival when compared with open cohorts in the literature. IRCs are of concern and warrant follow up and long-term antibiotic treatment.

Abstract [en]

Objective: The purpose of this multicentre study was to analyse the outcome of thoracic endovascular aortic repair (TEVAR) in patients with ruptured descending thoracic aortic aneurysm (rDTAA). Methods: This is a nationwide retrospective study including all patients who underwent TEVAR for rDTAA at six major vascular university centres in Sweden between January 2000 and December 2015. Outcome measures were analysed using Kaplan-Meier estimator and multivariable Cox regression. Results: There were 140 patients (age [mean +/- SD] 74.1 +/- 8.8 years; 56% men; aneurysm size 64.8 +/- 19 mm), with rDTAA. In 53 patients (37.9%), the left subclavian artery was covered, and in 25 patients (17.9%) arch vessel revascularisation was performed. In total, 61/136 patients (45%) had a major complication within 30 days post TEVAR. Stroke (n = 20; 14.7%) was the most common complication, followed by paraplegia (n = 13; 9.6%) and major bleeding (n = 13; 9.6%). TEVAR related complications during follow up included endoleaks 22.1% (30/136; 14 type 1a, six type 1b, 10 not defined). In total, re-interventions (n = 31) were required in 27/137 (19.7%) patients. The median follow up time was 17.0 months (range 0-132 months). The Kaplan-Meier estimated survival was 80.0% at one month, 71.7% at three months, 65.3% at one year, 45.9% at three years, and 31.9% at five years. Age (HR 1.03; 95% CI 1.00-1.07; p = .046), history of stroke (HR 2.35; 95% CI 1.194.63; p = .014), previous aortic surgery (HR 2.11; 95% CI 1.15-3.87; p = .016) as well as post-operative major bleeding (HR 4.40; 95% CI 2.20-8.81; p = .001), stroke (HR 2.63; 95% CI 1.37-5.03; p = .004), and renal failure (HR 8.25; 95% CI 2.69-25.35; p = .001) were all associated with mortality. Conclusions: This nationwide multicentre study of patients with rDTAA undergoing TEVAR showed acceptable short- but poor long-term survival. Adequate proximal and distal aortic sealing zones are important for technical success. High risk patients and post-operative complications need to be further addressed in an effort to improve outcome.

Abstract [en]

Objectives: To evaluate outcomes after endovascular treatment of abdominal aortic aneurysms (AAA) involving the renovisceral arteries and to compare outcomes after fenestrated/branched endovascular aortic repair (f/b-EVAR), chimney/periscope EVAR (ch-EVAR), and bailout ch-EVAR.

Methods: A retrospective multicenter study including all patients with AAA involving the renovisceral segment, treated with f/b-EVAR, ch-EVAR, or bailout ch-EVAR, between 1 January 2005 and 30 June 2015, in three Swedish vascular centers. Patient charts were reviewed for data. Renovisceral stent graft patency was assessed on follow-up CT. Mortality was cross-checked against the Swedish Population Registry. Bailout ch-EVAR was defined as a perioperative decision of renovisceral endografting, as the artery was accidentally covered, or as the aneurysm neck sealing zone was considered inadequate.

Results: Of the 99 identified patients (76 men; mean age 74 years (range 58-89 years)), 68 underwent f/b-EVAR, 18 ch-EVAR, and 13 bailout ch-EVAR. Follow-up lasted for a median of 3.2 years (Q1, Q3 (2.1, 4.7 years)). Elective surgery comprised 87.9% (n = 87) of the cases. Six patients died within 30 days, and the 30-day mortality after elective surgery was 4.6% (95% CI, 1.3%-11.4%) overall, 1.6% after f/b-EVAR (95% CI, 0.0%-11.4%), 15.4% after ch-EVAR (95% CI, 1.9%-45.4%), and 10.0% (95% CI, 0.3%-44.5%) after bailout ch-EVAR. During follow-up, there were 16 secondary interventions, of which 75% (n = 12) were performed within six months after the primary intervention. Compared with f/b-EVAR, ch-EVAR was associated with a higher degree of type 1 endoleaks (1.5% vs. 22.2%, P = 0.001) and re-interventions during follow-up (13.2% vs. 33.3%, P = 0.046). The overall assisted target vessel patency was 96.1% (95% CI, 91.7%-98.6%) at one year and 95.2% (95% CI, 89.2%-98.4%) at two years.

Conclusions: Results after EVAR involving endografting of renovisceral arteries from three centers in Sweden with medium volumes are consistent with results previously reported from centers with larger volumes.
