Under the direction of the Association of Program Directors in Vascular Surgery, a survey was mailed to vascular surgery residents (VSRs), general surgery chief residents (GS-CRs), and fourth-year medical students (MSs) to better define reasons why trainees do and do not choose vascular surgery as a career. ⋯ These findings may help vascular surgery program directors devise strategies to attract future trainees. The importance of mentorship to general surgery junior residents and medical students in choosing vascular surgery cannot be overestimated. Endovascular capabilities of vascular surgeons have an increasingly positive role in career choice by GS-CRs and VSRs, but these residents express increasing concerns about potential loss of patients to other specialists. Lifestyle concerns are the most important reasons why medical students do not choose vascular surgery as a career.

Comparative Study
Role of prophylactic temporary inferior vena cava filters placed at the ICU bedside under intravascular ultrasound guidance in patients with multiple trauma.
Patients with multiple trauma often have injuries that preclude the use of anticoagulation therapy or sequential compression device prophylaxis. Temporary inferior vena cava (IVC) filters (IVCFs) offer protection against pulmonary embolism during the early immediate injury and perioperative period, when risk is highest, while averting potential long-term sequelae of permanent IVCFs. The objective of this study was to evaluate the efficacy of prophylactic, temporary IVCF placement at the intensive care unit bedside under real-time intravascular ultrasound (IVUS) guidance in patients with multiple trauma. ⋯ Patients with multiple trauma often have injuries that preclude the use of anticoagulation therapy or sequential compression device prophylaxis. Temporary inferior vena cava filters (IVCFs) offer protection against pulmonary embolism during the perioperative and immediate injury period, when risk is highest. Ninety-four patients with multiple trauma underwent prophylactic, temporary IVCF placement at the intensive care unit bedside under real-time intravascular ultrasound. One pulmonary embolism occurred during follow-up after filter retrieval, and 1 insertion site femoral vein deep venous thrombosis occurred. Ninety-one of 94 IVCFs (96.8%) were placed without complication. Thirty-one patients underwent uneventful retrieval of IVCFs after anticoagulation prophylaxis was initiated. Forty-four filters were not removed, because of severity of injury (n = 41) or because of trapped thrombus within the filter (n = 3). Prophylactic, temporary IVCFs placed under intravascular ultrasound guidance at the bedside in patients with multiple trauma is simple, safe, and an effective bridge to anticoagulation therapy.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Heparin-bonded Dacron or polytetrafluorethylene for femoropopliteal bypass: five-year results of a prospective randomized multicenter clinical trial.
Dacron was largely abandoned for femoropopliteal bypass 30 years ago, because better patency rates were achieved with saphenous vein. Despite the range of potential prosthetics, polytetrafluoroethylne (PTFE) clearly predominates in current femoropopliteal practice. We compared heparin-bonded Dacron (HBD) with PTFE in a randomized multicenter clinical trial. ⋯ Significantly better patency rates were achieved with HBD than with PTFE at 3 years (P < .044), but the difference was no longer statistically significant at 5 years (P < .055). The incidence of major limb amputation, however, was significantly greater (P < .025) in the PTFE group compared with the HBD group at both 3 and 5 years of follow-up.

Review Case Reports
Endoluminal repair of carotid artery pseudoaneurysms: a word of caution.
This report describes our results with covered endoluminal stents in the management of 4 patients with carotid artery pseudoaneurysms (PSAs) following carotid endarterectomy (CEA). Two patients had symptomatic embolization of thrombus from the PSA's into branches of the middle cerebral arteries (MCA) during deployment of the stents. ⋯ While endoluminal therapy of carotid PSAs in an effective method to exclude PSAs, embolization of thrombus is a potential hazard. The long-term patency of covered stents in the carotid artery is unknown.

Comparative Study
Clinical effect of abdominal aortic aneurysm endografting: 7-year concurrent comparison with open repair.
We compared the effectiveness and clinical outcome of open repair versus endovascular aortic aneurysm repair (EVAR) in achieving prevention of abdominal aortic aneurysm (AAA)-related death and graft-related complications. ⋯ Our data suggest that at a maximum follow-up of 7 years, patients who undergo EVAR show lower perioperative and late aneurysm-related mortality compared with a younger and substantially healthier group of patients with aneurysms treated with open repair. The higher need for secondary procedures in the endovascular group did not affect superiority of the overall performance of EVAR in the early and late intervals.
