Predicting Features of Visceral Stent Failure in Fenestrated Endovascular Aortic Aneurysm Repair.

Purpose: Visceral stents in fenestrated endovascular aortic repair (FEVAR) have a significant risk of complications and carry a considerable burden of reinterventions. The aim of this study is to identify preoperative and intraoperative predictors of visceral stent failure.

Materials: A retrospective review of 75 consecutive FEVARs in a single center from 2013 to 2021 was undertaken.

Comparison between open repair with suprarenal clamping and fenestrated endovascular repair for unruptured juxtarenal abdominal aortic aneurysms.

Background: Management of juxtarenal abdominal aortic aneurysms (JRAAA) remains challenging. Both open surgical and endovascular options are feasible, however, there is lack of level 1 evidence to support one modality over the other. Operative interventions frequently necessitate either open repair with a suprarenal clamp positioning (ORSRC) or complex endovascular repair (EVAR) with fenestrated (fEVAR) or parallel stent grafts (chEVAR).

Outcomes of Sub-threshold Abdominal Aortic Aneurysms Undergoing Surveillance in Patients Aged 85 Years or Over.

Objective: Despite an increasing elderly population there is limited evidence regarding the surveillance and management of small abdominal aortic aneurysms (AAAs) in octogenarians. This study investigated outcomes of patients aged ≥85 years undergoing AAA surveillance to identify whether discontinuation of surveillance might be safe.

Methods: This was a retrospective cohort study of all patients aged 85 years undergoing surveillance with a small (30-54 mm) AAA between January 2007 and November 2017.

A Comparison of Manual and Three-Dimensional Modalities in Predicting Nellix Polymer Volume.

Purpose: Achieving an effective seal with the Nellix endovascular aneurysm system is dependent on filling the stent bags with an appropriate volume of polymer. Calculating this volume preoperatively is essential and can be performed manually or using three-dimensional (3D) software. The aim of this project was to compare the accuracy of these two methods relative to the actual polymer volume used.

Endovascular abdominal aortic aneurysm sealing: A systematic review of early outcomes.

Objectives There has been a clear move towards endovascular repair of abdominal aortic aneurysms owing to better peri-operative outcomes compared with open surgical repair. However, follow-up has continued to reveal relatively high rates of endoleaks and re-interventions. Improvements in endovascular stent-grafts aim to decrease these complications.

Outcomes of endovascular aneurysm repair with 2 different endograft systems with suprarenal fixation in patients with hostile infrarenal aortic anatomy.

Objective: To evaluate 2 different aortic endograft systems with suprarenal fixation in patients with unfavorable neck morphology.

Methods: A prospective observational study assigning patients with abdominal aortic aneurysm with unfriendly neck anatomy treated with 2 different endograft systems (Endurant and Zenith) was conducted. The log-rank test was applied to investigate the differences in cumulative outcome parameters.

Reduction of ischemia-reperfusion injury in the rat kidney by FTY720, a synthetic derivative of sphingosine.

Background: The current shortage of organ donors has led many centers to use marginal and nonheart-beating donors (NHBDs). Recent research has implicated the infiltration of lymphocytes as an important mediator of ischemia-reperfusion injury (IRI). FTY720 is an immunosuppressant that promotes lymphocyte sequestration into lymph nodes.
