The sac evolution imaging follow-up after endovascular aortic repair: An international expert opinion-based Delphi consensus study.

Objective: Management of follow-up protocols after endovascular aortic repair (EVAR) varies significantly between centers and is not standardized according to sac regression. By designing an international expert-based Delphi consensus, the study aimed to create recommendations on follow-up after EVAR according to sac evolution.

Methods: Eight facilitators created appropriate statements regarding the study topic that were voted, using a 4-point Likert scale, by a selected panel of international experts using a three-round modified Delphi consensus process.

Editor's Choice -- European Society for Vascular Surgery (ESVS) 2024 Clinical Practice Guidelines on the Management of Abdominal Aorto-Iliac Artery Aneurysms.

Objective: The European Society for Vascular Surgery (ESVS) has developed clinical practice guidelines for the care of patients with aneurysms of the abdominal aorta and iliac arteries in succession to the 2011 and 2019 versions, with the aim of assisting physicians and patients in selecting the best management strategy.

Methods: The guideline is based on scientific evidence completed with expert opinion on the matter. By summarising and evaluating the best available evidence, recommendations for the evaluation and treatment of patients have been formulated.

Certification of Basic Skills in Endovascular Aortic Repair Through a Modular Simulation Course With Real Time Performance Assessment.

Objective: Endovascular aortic repair (EVAR) is being used increasingly for the treatment of infrarenal abdominal aortic aneurysms. Improvement in educational strategies is required to teach future vascular surgeons EVAR skills, but a comprehensive, pre-defined e-learning and simulation curriculum remains to be developed and tested. EndoVascular Aortic Repair Assessment of Technical Expertise (EVARATE), an assessment tool for simulation based education (SBE) in EVAR, has previously been designed to assess EVAR skills, and a pass limit defining mastery level has been set.

Iodine density mapping for the diagnosis of acute bowel ischemia using fast kV-switching dual-energy CT.

Purpose: To evaluate the diagnostic capabilities of a supplementary color ramped iodine density map compared to virtual monoenergetic images (VMIs) at 74 keV in the diagnosis of acute bowel ischemia (ABI).

Methods: Data for this study were prospectively gathered and retrospectively evaluated. Patients referred to the Department of Diagnostic Radiology between October 2020 and August 2022 on the suspicion of ABI and underwent surgery < 12 h following fast kV-switching venous phase abdominal dual-energy CT (DECT) were consecutively included.

Anatomical suitability for branched endovascular aortic arch repair and balloon-expandable bridging stent grafts in a cohort of patients previously treated with a hybrid approach.

Objective: We assessed the suitability of two triple branch arch devices (aBranch) (Terumo aortic and Cook Medical) and a balloon-expandable covered stent (VBX, W. L. Gore & Associates, Johnson & Johnson) to incorporate the brachiocephalic trunk (BCT) in a cohort previously treated with hybrid thoracic endovascular repair (TEVAR).

Systematic Review and Meta-Analysis of the Incidence of Rupture, Repair, and Death of Small and Large Abdominal Aortic Aneurysms under Surveillance.

Background: The ultimate goal of treating patients with abdominal aortic aneurysms (AAAs) is to repair them when the risk of rupture exceeds the risk of repair. Small AAAs demonstrate a low rupture risk, and recently, large AAAs just above the threshold (5.5-6.

Danish Nationwide Study on Surgical Treatment of Infective Native Abdominal Aortic Aneurysms.

Objective: This study aimed to describe surgical trends, survival, and infection related complications (IRC) in a Danish cohort of patients with infective native aortic aneurysms (INAAs).

Methods: A retrospective nationwide cohort study including all patients in Denmark who were surgically treated for abdominal INAA between 2000 and 2020 was conducted. Patients were identified through the Danish vascular registry, Karbase, which is a database registering all patients treated with vascular surgery in Denmark.

Single branch arch stent graft combined with laser fenestration in the treatment of a zone two penetrating thoracic aortic ulcer.

We present the case of a 75-year-old man with a symptomatic penetrating aortic ulcer located in zone 2 on the arch inner curve between the left subclavian artery and left carotid artery treated using a single branch thoracic endovascular aortic repair combined with in situ laser fenestration. The patient underwent a successful procedure with no neurologic impairment and was discharged on the second postoperative day. The postoperative follow-up showed a well-excluded penetrating aortic ulcer.

Simulation-Based Education of Endovascular Scrub Nurses Reduces Stress and Improves Team Performance.

Introduction: Endovascular procedures have become commonplace in vascular surgery. This development calls for new training strategies for future specialists. Most simulation-based education (SBE) programs have a monodisciplinary focus on physicians, although successful surgery is a multidisciplinary team effort.

T Branch Repair of Ruptured a Type IV Thoracoabdominal Aortic Aneurysm Complicated by Renal Branch Occlusion.

A 60-year male patient presented with a thoracoabdominal aortic aneurysm rupture, which was treated emergently with a modified off-the-shelf t-Branch stent-graft (COOK Medical Inc). The sole renal branch occluded 1 month after TEVAR due to branch compression, and the patient became anuric and temporarily dialysis-dependent. Despite the prolonged renal ischemia time, the occluded renal branch was successfully opened with thrombolysis and reinforced with a bare-metal stent.

Gastrointestinal Applications of Iodine Quantification Using Dual-Energy CT: A Systematic Review.

Dual-energy computed tomography (DECT) can estimate tissue vascularity and perfusion via iodine quantification. The aim of this systematic review was to outline current and emerging clinical applications of iodine quantification within the gastrointestinal tract using DECT. The search was conducted with three databases: EMBASE, Pubmed and The Cochrane Library.

New Technique for Preconditioning of the Spinal Cord Before Endovascular Repair of Descending Thoracic and Thoracoabdominal Aortic Aneurysms.

To propose a new simplified technique to occlude multiple segmental arteries for staging and preconditioning of the spinal cord to decrease the potential for spinal cord ischemia after thoracic and thoracoabdominal aortic aneurysm repair. A thoracic stent-graft that flares out to a maximum of 51 mm is deployed in a standard fashion covering all segmental arteries where graft-wall apposition occurs in the first ~20 cm of the aneurysm. The segmental arteries are always closed at their ostia in contrast to selective coil embolization, where there is a risk of more peripheral closure.
