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.

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.

Comparative Study
Comparison of angioplasty and stenting with cerebral protection versus endarterectomy for treatment of internal carotid artery stenosis in elderly patients.
Carotid angioplasty and stenting (CAS) is being evaluated as an alternative to carotid endarterectomy (CEA) for treatment of severe carotid artery stenosis. Because CAS does not require general anesthesia and is less traumatic, it might be especially advantageous in older patients, but data comparing these 2 treatment methods in older patients are scarce. ⋯ Despite the use of cerebral protection devices the neurologic complication rate in patients aged 75 years and older associated with CAS was significantly higher than with CEA performed by highly skilled surgeons at our academic institution. Although this finding is mainly based on a significantly higher rate of minor stroke in the CAS group, the common practice of preferentially submitting older patients to CAS is questionable, and should be abandoned until the results of further randomized trials are available.
