Hypogastric artery embolization (HAE) is often performed in endovascular aortoiliac aneurysm repair to prevent potential endoleak, and this can be associated with pelvic ischemic sequelae. This prospective study was performed to evaluate the clinical outcome of HAE in patients who underwent endovascular aortoiliac aneurysm repair. During a 15-month period, 12 ...

Concerns over penile size and a desire for a longer penis are common in the male population. The number of male patients seeking an andrological consultation for the problem of 'short penis' is increasing. We looked at the numbers of patients presenting to a University andrology clinic over a 2-y ...

The burden of clinically relevant noncoronary atherosclerotic occlusive disease in patients with abdominal aortic aneurysms (AAAs) is poorly defined. Furthermore, the cost-effectiveness of routine versus selective preoperative noninvasive examination of the carotid and lower extremity arterial beds has not been established in patients who undergo elective AAA repair. Diagnostic vascular ...

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 ...
Qureshi A I - - 2001
BACKGROUND AND PURPOSE: Previous studies have suggested that patients with carotid stenosis who are candidates for endarterectomy can be effectively identified on the basis of carotid Doppler ultrasound alone. Before widespread acceptance of this policy, the accuracy of carotid Doppler ultrasound outside selected centers and clinical trials needs to be ...
