JOURNAL OF VASCULAR SURGERY. A meta-analysis of outcomes of endovascular abdominal aortic aneurysm repair in patients with hostile and friendly neck anatomy

George A. Antoniou, MD, PhD, George S. Georgiadis, MD, Stavros A. Antoniou, MD, Ganesh Kuhan, MD, FRCS, David Murray, MD, FRCS

Background: An increasing number of abdominal aortic aneurysms with unfavorable proximal neck anatomy are treated with standard endograft devices. Skepticism exists with regard to the safety and efficacy of this practice.

JOURNAL OF VASCULAR SURGERY. Results of polytetrafluoroethylene-covered nitinol stents crossing the inguinal ligament

Keith D. Calligaro, MD, Praveen Balraj, MD , Neil Moudgill, MD , Atul Rao, MD , Matthew J. Dougherty, MD , Joshua Eisenberg, MD

Objective: Placement of arterial endoprostheses across the inguinal ligament is generally thought to be contraindicated for fear of device kinking, fracture, or occlusion and possible obliteration of the deep femoral artery (DFA). We present a series of selected patients who underwent insertion of polytetrafluoroethylene-covered nitinol stents (Viabahn stent grafts. W. L. Gore and Associates Inc, Flagstaff, Ariz) crossing the middle common femoral artery (CFA) on an emergency basis or who were considered high risk for open surgery.

Objective: This study assessed the risk of left subclavian artery (LSA) coverage and the role of revascularization in a large population of patients undergoing thoracic endovascular aortic aneurysm repair.

JOURNAL OF VASCULAR SURGERY.Predicting the learning curve and failures of total percutaneous endovascular aortic aneurysm repair

Carlos F. Bechara, MD, MS, Neal R. Barshes, MD, MPH, George Pisimisis, MD, Huiting Chen, MD, Taemee Pak, BS, Peter H. Lin, MD, Panagiotis Kougias, MD

Introduction: Percutaneous endovascular aneurysm repair (PEVAR) has been shown to be feasible; however, technical success is variable, reported to be between 46.2% and 100%. The objective of this study was to quantify the learning curve of the PEVAR closure technique and identify predictors of closure failure

JOURNAL OF VASCULAR SURGERY. Differences in readmissions after open repair versus endovascular aneurysm repair

Kevin Casey, MD, Tina Hernandez-Boussard, PhD, MPH, Matthew W. Mell, MD, Jason T. Lee, MD

Objective: Reintervention rates after repair of abdominal aortic aneurysm (AAA) are higher for endovascular repair (EVAR) than for open repair, mostly due to treatment for endoleaks, whereas open surgical operations for bowel obstruction and abdominal hernias are higher after open repair. However, readmission rates after EVAR or open repair for nonoperative conditions and complications that do not require an intervention are not well documented. We sought to determine reasons for all-cause readmissions within the first year after open repair and EVAR.

JOURNAL OF VASCULAR SURGERY. Reintervention for distal stent graft-induced new entry after endovascular repair with a stainless steel-based device in aortic dissection

Shih-Hsien Weng, MD, Chi-Feng Weng, MD, Wei-Yuan Chen, MD, Chun-Yang Huang, MD, I-Ming Chen, MD, Chun-Ku Chen, MD, Chiao-Po Hsu, MD, PhD, Chun-Che Shih, MD, PhD

Objective: Stent graft-induced new entry (SINE) has been increasingly observed after thoracic endovascular aortic repair (TEVAR) for aortic dissection. We investigated the mechanism of late distal SINE, prevention strategies, proper size selection of the stent graft, and implantation sequence.

JOURNAL OF VASCULAR SURGERY. Clinical efficacy of concomitant tibial interventions associated with superficial femoral artery interventions in critical limb ischemia

Christopher J. Smolock, MD, Javier E. Anaya-Ayala, MD, Hosam F. El-Sayed, MD, Joseph J. Naoum, MD, Alan B. Lumsden, MD, Mark G. Davies, MD, PhD, MBA

Background: Combined superficial femoral artery (SFA) and tibial angioplasty (TA) are a common treatment for critical limb ischemia. Poor tibial runoff significantly compromises durability and clinical effectiveness of SFA interventions. The aim of this study is to determine clinical and anatomic outcomes of SFA interventions in patients with equally compromised runoff, with and without concomitant TA.
