OBJECTIVE Carotid endarterectomy (CEA) guidelines in symptomatic carotid stenosis are based on NASCET and ECST criteria with 70% or greater carotid stenosis as estimated from a catheter angiogram the major indication. This has several problems: (1) lack of reliable correlation between non-invasive imaging and catheter angiography, which has been largely(More)
PURPOSE The purpose of this study was to determine the variation in ankle-brachial pressure index (ABPI) measurements in routine clinical practice. METHODS Analysis was done of preoperative and postoperative ABPIs in 130 limbs contralateral to those undergoing femoral bypass grafting in 123 patients over a 15-month period. RESULTS The mean initial ABPI(More)
INTRODUCTION Prosthetic arteriovenous grafts (AVGs) in the lower extremity represent a useful alternative for hemodialysis vascular access when all upper limb access sites have been used or in some patients when freedom of both hands is necessary during dialysis. Reported complications include an increased risk of infection and limb ischemia. This study(More)
BACKGROUND Venous duplex ultrasound scanning (VDUS) has been shown to be an accurate non-invasive means to diagnose symptomatic deep venous thrombosis (DVT). The aim of our study was to determine whether bilateral VDUS is necessary in patients who present with symptoms of DVT. METHODS We retrospectively reviewed the results of bilateral lower extremity(More)
BACKGROUND Carotid endarterectomy is known to benefit both symptomatic and asymptomatic patients with high-grade internal carotid artery stenosis. Duplex scanning is the 'gold standard' for non-invasive preoperative investigation of carotid artery stenosis. The aim of the present study was to analyse the indications for duplex scanning and to identify other(More)
