Consensus statement on the interhospital transfer of patients with acute aortic syndrome: TRAVERSING Delphi study.

Background: Standardisation of referral pathways and the transfer of patients with acute aortic syndromes (AAS) to regional centres are recommended by NHS England in the Acute Aortic Dissection Toolkit. The aim of the Transfer of Thoracic Aortic Vascular Emergencies to Regional Specialist INstitutes Group study was to establish an interdisciplinary consensus on the interhospital transfer of patients with AAS to specialist high-volume aortic centres.

Methods: Consensus on the key aspects of interhospital transfer of patients with AAS was established using the Delphi method, in line with Conducting and Reporting of Delphi Studies guidelines.

Umbrella review and meta-analysis of reconstructed individual patient data of mortality following conventional endovascular and open surgical repair of infrarenal abdominal aortic aneurysm.

Objectives: This umbrella review aims to quality assess published meta-analyses, conduct a de-novo meta-analysis of the available randomized control trials (RCTs), and test the hypothesis that there is a long-term difference in mortality between OSR and EVAR.

Methods: A systematic search was conducted in MEDLINE and EMBASE's bibliographic databases (June 2022). Data were extracted using standardized extraction forms.

Fractured Sealing Rings in a Fenestrated Anaconda Stent-Graft.

An 81 year-old man presented with an asymptomatic juxtrarenal abdominal aortic aneurysm and was subsequently treated with a fenestrated endovascular Anaconda stent-graft. Surveillance imaging within the first postoperative year demonstrated a lower proximal sealing ring fracture. In the second postoperative surveillance year, the upper proximal sealing ring was also fractured with extension of the wire into the right paravertebral space.

Characterising the incidence and mode of visceral stent failure after fenestrated endovascular aneurysm repair (FEVAR).

Background: In FEVAR, visceral stents provide continuity and maintain perfusion between the main body of the stent and the respective visceral artery. The aim of this study was to characterise the incidence and mode of visceral stent failure (type Ic endoleak, type IIIa endoleak, stenosis/kink, fracture, crush and occlusion) after FEVAR in a large cohort of patients at a high-volume centre.

Methods: A retrospective review of visceral stents placed during FEVAR over 15 years (February 2003-December 2018) was performed.

Endovascular vs. Medical Management for Uncomplicated Acute and Sub-acute Type B Aortic Dissection: A Meta-analysis.

Objective: The aim was to compare peri-operative and late outcomes of patients with acute and subacute uncomplicated type B aortic dissection (uTBAD) treated by thoracic endovascular aortic repair (TEVAR) or best medical therapy (BMT).

Methods: This was a Systematic review and meta-analysis of observational studies and randomised controlled trials (RCTs). The review was undertaken according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and registered with the International Prospective Register of Systematic Reviews (number: CRD42018094607).

Total psoas area predicts medium-term mortality after lower limb revascularization.

Background: Analytic morphometry is a novel concept in perioperative risk assessment. Low core muscle mass assessed by morphometry is associated with frailty and has been demonstrated to be an independent predictor of postoperative complications and mortality in oncologic, transplant, and aneurysm surgery. We aimed to study associations between core muscle mass and complication rates, length of hospital stay, and survival after surgical lower limb revascularization.

Late Rupture of Abdominal Aortic Aneurysm After Previous Endovascular Repair: A Systematic Review and Meta-analysis.

Purpose: To report a systematic literature review of late rupture of abdominal aortic aneurysm (AAA) after endovascular aneurysm repair (EVAR) and the results of a pooled analysis of causes, treatment, and outcomes.

Methods: Electronic information sources and bibliographic reference lists were interrogated using a combination of free text and controlled vocabulary searches; 11 articles were ultimately identified that fulfilled the inclusion criteria. The articles reported a total of 190 patients who were included in the qualitative and quantitative synthesis.

Aortic Dehiscence During Endovascular Sealing for Ruptured Abdominal Aortic Aneurysms.

Purpose: To present a case of aneurysm disruption during endovascular sealing of a ruptured abdominal aortic aneurysm.

Case Report: A 91-year-old woman presented with a ruptured abdominal aortic aneurysm. Her aneurysm morphology was unsuitable for standard or fenestrated endovascular repair, whereas open repair was considered to have an increased perioperative risk owing to multiple comorbidities.

Sheath-shunt technique for avoiding lower limb ischemia during complex endovascular aneurysm repair.

Complex aortic aneurysms are now being repaired by endovascular techniques, albeit with a potentially increased risk of lower limb ischemia-reperfusion injury. We report a simple technique to maintain perfusion to the lower limb during endovascular repair, using one additional introducer sheath placed antegrade, distal to the stent graft introduction site, and connected to the side arm of the working sheath in the contralateral artery. This allows continuous perfusion of the limb distal to the main stent graft introduction site.

Total endograft replacement of aortic arch.

Total endovascular replacement of the aortic arch is a complex procedure that is often favoured when the pathology anatomy precludes a standard median sternotomy. Here we present the case of endograft repair in a 79 year old male with 6.5 cm arch aneurysm and 5.

Evaluating training for a simulated team in complex whole procedure simulations in the endovascular suite.

Introduction: Simulators supporting the development of technical skills for complex procedures are gaining prominence. Safe performance of complex procedures requires effective team interactions. Our research group creates 'whole' procedure simulations to produce the psychological fidelity of clinical settings.

Cognitive training improves clinically relevant outcomes during simulated endovascular procedures.

Objectives: Virtual reality (VR) simulation has been suggested to objectively assess endovascular skills. The aim of this study was to determine the impact of cognitive training on technical performance of inexperienced subjects on a commercially available VR simulator (VIST, Vascular Intervention Simulation Trainer, Mentice, Gothenburg, Sweden).

Methods: Forty-seven subjects treated an identical virtual iliac artery stenosis endovascularly.

Should we train the trainers? Results of a randomized trial.

Background: The development of efficient training methods in surgery is increasingly important. The effectiveness of training trainers is unclear. This study was designed to determine the effect on their trainees' performance of instructing trainers in a specific cognitive training method.

Endovascular skills training and assessment.

Objective: Evolving endovascular therapies have transformed the management of vascular disease. At the same time, the increasing use of non-invasive vascular imaging techniques has reduced the opportunities to gain the required basic wire and catheter handling skills by performing diagnostic catheterizations. This article reviews the evidence for alternative tools currently available for endovascular skills training and assessment.
