The type of anesthesia used during aneurysm repair affects postoperative outcomes for the patient. Although endovascular aneurysm repair (EVAR) appears to improve surgical outcomes, by convention, general anesthesia remains predominantly used. The aim of this study was to compare the impact of the type of anesthesia (ie, locoregional versus general...

This article describes a new, less invasive prosthetic graft anastomotic technique that uses self-expanding stent grafts that are "telescoped" into aortic branches. This method, the VORTEC (Viabahn Open Revascularization TEChnique), obviates the need for potentially difficult complete vessel exposure and graft anastomoses, thereby reducing the dura...

Arterial embolization is a frequently performed adjunctive maneuver prior to laparoscopic splenectomy or nephrectomy to facilitate laparoscopic dissection and reduce intraoperative bleeding. However, little is known regarding the effect of laparoscopic stapling across thrombosed vessels with imbedded embolic materials. This study analyzed the stapl...

Screening for abdominal aortic aneurysm (AAA) has been suggested for older men. Our aim was to determine the effect of participant selection on prevalence and treatment suitability. Men aged 65 to 75 years attending cardiology clinics composed the high-risk group; the control group was from the community. AAA screening was performed, with follow-up...

Ischemic preconditioning (IP) uses transient ischemia to render tissues tolerant to subsequent, prolonged ischemia. This study sought to evaluate factors that contributed to the development of cerebral ischemia during PercuSurge balloon (Medtronic, Santa Rosa, CA) occlusion in patients undergoing carotid angioplasty and stenting (CAS). The PercuSur...

Stroke is a leading cause of disability and the third leading cause of death. Landmark studies have demonstrated that carotid endarterectomy (CEA) reduced the risk of stroke among selected patients with carotid stenosis. Renal insufficiency is a known risk factor for stroke and appears to be an independent risk factor for poor outcome after CEA. St...

The aim of this study was to determine platelet activity and reactivity and the effects of unfractionated heparin (UFH) and enoxaparin on platelet function during carotid eversion endarterectomy under local anesthesia. Twenty symptomatic patients undergoing carotid endarterectomy were randomly assigned to either 5,000 units of UFH or body weight-ad...

The objective of this study was to determine whether hypertension is a risk factor for aneurysm enlargement in patients with an untreated type II endoleak after endovascular abdominal aortic aneurysm repair (EVAR). Between January 2000 and December 2005, 296 patients underwent elective EVAR using a bifurcated Zenith stent graft. Forty-nine (17%) pa...

Thrombin is a common hemostatic drug used in surgical practice for over 100 years because of its simplicity and efficacy. Thrombin converts fibrinogen to fibrin, activates platelets, and induces vascular contraction. It is available in multiple forms, including human thrombin, bovine thrombin, and, most recently, human recombinant thrombin. Over 10...

Arterial injury during treatment of varicose veins is a rare but devastating complication that can lead to leg amputation. Approximately 6,000 patients were treated by either surgery (4,800 patients treated by ligation, stripping, and stub avulsion) or ultrasound-guided foam sclerotherapy (USGS) (1,200 patients) in the last 7 years for venous insuf...
