OBJECTIVES to determine whether duplex ultrasonography alone is an adequate examination prior to carotid endarterectomy. DESIGN prospective, randomised, single centre study. MATERIAL AND METHODS all patients with carotid bifurcation stenosis greater than 70% - based on duplex scanning - were randomised to arteriography followed by carotid surgery (Group A n=96) or carotid surgery alone (Gro...

PURPOSE To demonstrate the efficacy of carotid duplex ultrasound to diagnose common carotid artery occlusion (CCAO) and to define the clinical features of CCAO. METHODS We reviewed 5400 carotid duplex ultrasonograms obtained over a 7-year period for suspected carotid artery disease. In cases of CCAO, medical records were reviewed. RESULTS Thirteen cases (0.24%) of CCAO were diagnosed by car...

Background: Erectile dysfunction (ED) is a growing common health problem that affects men of different age groups. Despite it is thought to be a para-aging disease, it affects young and middle aged men as well. Color duplex Doppler is a non-invasive tool of evaluation of the vascular mechanism of erection in patients suspected to have an organic cause of ED. Objective: To demonstrate the color ...

Duplex ultrasound is currently used both for screening and for preoperative assessment of the carotid arteries and has completely replaced carotid angiography for the latter purpose in many institutions. The study aimed to identify resistivity index abnormalities in the common carotid arteries in patients with occluded or severely stenosed internal carotid arteries. Sixteen patients with severe...

INTRODUCTION Although intervention in patients with symptomatic carotid disease is generally accepted as beneficial, the management of asymptomatic disease is still controversial. We wanted to introduce and discuss treatment options in a patient with asymptomatic carotid stenosis and high embolic potential lesions of common and internal carotid artery detected by multidetector computed tomograp...

PURPOSE Effective treatment of abdominal aortic aneurysm (AAA) requires both early detection and timely repair to reduce aneurysm-related mortality. The purpose of this prospective study was to evaluate the utility of a hand-held ultrasonography (US) device in AAA screening in a Veterans Affairs vascular surgical service. METHODS During a 16-month period, patients with risk factors for AAA we...

The advantages and inadequacies of the currently available techniques to measure regional blood flow in the lower limbs are being reviewed. Thermodilution technique and local 133xenon washout technique have the advantage of allowing determination of blood flow during exercise, while venous occlusion plethysmography and pulsed-Doppler duplex ultrasonography only allow determination of blood flow...
