Objectives: To assess whether the publication of the EVAR Trial 1 (June 2005) had an impact on practice in our centre.
Methods: A retrospective study of all patients undergoing abdominal aortic aneurysm (AAA) repair in Leicester, from the year before publication of EVAR Trial 1 data to the year after (July 2004 - June 2006). Data from the study period was then compared with practice over the last six years (January 2000 - December 2006).
Results: The proportion of endovascular aneurysm repairs (EVARs) did not change significantly in the year following publication of EVAR Trial 1 data (52% VS 57%, p=0.64). The mean age of patients offered open repair (OR) fell in the year following publication (69 years +/- 6.68 vs 72 years +/- 5.71, p<0.05). Despite this, there was no significant change in their fitness (physiological POSSUM scores: 19.2 +/- 3.91 vs 18.2 +/- 3.74, P=0.30). There was an overall increase in the percentage of EVARs in the years 2000 (28%) to 2006 (57%).
Conclusion: There was no significant difference in the percentage of EVARs between the two years of study. However, over the last six years, there has been an increasing number performed in our unit and we now do more EVARs than ORs.

Purpose: Our aim was to update evidence-based and consensus-based recommendations for the inhospital endovascular management of haemorrhage and vascular lesions in patients with multiple and/or severe injuries based on current evidence. This guideline topic is part of the 2022 update of the German Guideline on the Treatment of Patients with Multiple and/or Severe Injuries.
Methods: MEDLINE and Embase were systematically searched to June 2021.

Objective: Half of re-interventions after fenestrated and branched endovascular aortic repair (FB-EVAR) are target vessel related. Regarding bridging stent choice, existing data are controversial. This meta-analysis aimed to evaluate the performance of Advanta V12/iCAST as bridging stent in FB-EVAR.

Background: Intravascular ultrasound (IVUS) use in aortic endovascular interventions, including thoracic endovascular aneurysm repair (TEVAR) and endovascular aneurysm repair (EVAR), may have similar benefits to those seen in coronary and peripheral interventions, but limited utilization and outcome data exist.
Methods: Centers for Medicare and Medicaid Services claims data were used to identify patients undergoing TEVAR and EVAR from 2016 to 2023. Utilization trends were stratified by region, urbanicity, distressed communities index, community versus academic center, Medicare versus dual enrollment status, indication, urgency, and presence of dissection with malperfusion.
A 10-Year Retrospective Comparison of Endovascular and Open Aneurysm Repair for Infective Native Abdominal Aortic Aneurysm.

Division of Vascular Surgery, Department of Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.
Background: This study compared outcomes of endovascular (EVAR) and open aneurysm repair (OAR) in patients with infective native abdominal aortic aneurysms (INAAAs), evaluating perioperative and in-hospital mortality, antibiotic treatment duration, complications, overall survival rates, and reintervention-free times at 10 years.
Methods: A retrospective cohort study of 125 INAAA patients (80 EVAR, 45 OAR) diagnosed between January 2004 and December 2019 was conducted. Patients were categorized as fit or unfit for open surgery based on cardiac, respiratory, and renal status, following the guidelines established in the EVAR-1 and EVAR-2 trials.

Objective: Comprehensive endovascular aortic programmes need optimal infrastructure and multidisciplinary teams to manage complex aortic aneurysms. This study assessed the implementation of such a programme in two centres and its impact on fenestrated or branched endovascular aortic repair (FB-EVAR) outcomes.
Methods: A retrospective review of patients treated for complex abdominal and thoraco-abdominal aortic aneurysms (TAAAs) by FB-EVAR between 2013 and 2023 was undertaken.
