Spinal Cord Ischemia following Simultaneous EVAR and TEVAR for Concomitant Thoracic and Abdominal Aortic Aneurysms.

Background: In patients with abdominal aortic aneurysms, 10-20% has concomitant thoracic aortic pathologies. These are typically managed with staged endovascular aneurysm repair (EVAR) and thoracic endovascular aortic repair (TEVAR) due to a perceived higher risk of spinal cord ischemia from a simultaneous intervention. We aimed to determine the outcomes of patients undergoing simultaneous EVAR and TEVAR for concomitant aneurysms.

Contemporary outcomes of initial treatment strategy of endovascular intervention or bypass in patients with critical limb ischemia.

Objective: The optimal management for revascularization after critical limb ischemia (CLI) is controversial due to limited studies comparing long-term results of endovascular and open techniques. This study compares long-term outcomes after initial management of CLI via lower extremity bypass (LEB) and percutaneous vascular intervention (PVI).

Methods: This retrospective cohort study investigates outcomes of patients who underwent endovascular or open surgical management for CLI at a single institution from 2013-2018.

Background: Transcarotid artery revascularization (TCAR) has been shown to have half the rates of transient ischemic attack (TIA), stroke, and death compared with transfemoral carotid artery stenting (TFCAS). Successful outcomes of TFCAS require careful patient selection. The aim of this study was to determine the outcomes of TFCAS versus TCAR in both simple (type I) and complex (type II and III) aortic arches.

Extreme obesity is associated with angulation during inferior vena cava filter placement.

Background: Placement of inferior vena cava (IVC) filters can be complicated by venous injury, filter misplacement, angulation, insertion site injury, and procedure-related death. Currently, no studies exist evaluating the correlation between obesity and adverse outcomes of IVC filters. We aimed to assess the outcomes of IVC filter placement in the obese population using the Vascular Quality Initiative database.

Various Approaches to Open Removal of Inferior Vena Cava Filters.

Background: Inferior vena cava (IVC) filters may lead to complications of IVC filter placement including strut migration and caval erosion into adjacent organs. While percutaneous techniques for removal are preferred, in certain cases, this is not possible, and open retrieval is necessary. We present outcomes of 4 different approaches to 6 cases of open IVC filter retrieval.

Cross-clamp location affects short-term survival in patients undergoing open abdominal aortic aneurysm repair.

Introduction: Open abdominal aortic aneurysm (oAAA) repair in the era of advanced endovascular aortic techniques is used in challenging anatomy. The impact of the location of the proximal aortic cross-clamp (suprarenal [SR] vs infrarenal [IR]) on outcomes remains to be determined. The aim of this study was to analyze the effect of proximal aortic cross-clamp location on short-term and overall survival after oAAA repair in a contemporary series.

Validation of a preoperative prediction model for mortality within 1 year after endovascular aortic aneurysm repair of intact aneurysms.

Objective: Most would agree that at least 1-year survival is necessary after intact abdominal aortic aneurysm (AAA) repair to appropriately justify the cost and risk of the procedure.
