BACKGROUND Atherosclerotic lesions of the carotid and lower extremity arteries may be associated with renal artery stenosis and influence the management of patients with renal artery disease. OBJECTIVE To document the prevalence and clinical features of carotid and lower extremity arterial disease in patients with renal artery atherosclerosis. METHODS An analysis of baseline data on 149 pat...

After nearly 40 years, carotid endarterectomy has been shown to be of benefit to patients with symptomatic carotid territory ischaemia and greater than 70% stenosis of the relevant internal carotid artery. Cerebral angiography is performed before surgery and is not without risk. These risks must be added to those of surgery before recommending the procedure to patients. The study evaluated the ...

BACKGROUND AND PURPOSE Compared with the single-detector technique, multi-detector row CT angiography permits larger anatomic coverage that includes both the epiaortic and entire carotid circulations. We evaluated the accuracy of multi-detector row CT angiography by using multiplanar reformation (MPR) for measuring carotid artery diameters compared with that of rotational angiography. We also e...

PURPOSE To evaluate power Doppler imaging as a possible screening examination for carotid artery stenosis. MATERIALS AND METHODS In the principal pilot study, a prospective, blinded comparison of power Doppler imaging with duplex Doppler imaging, the reference-standard method, was conducted in 100 consecutive patients routinely referred for carotid artery imaging at a large, private multispec...

OBJECTIVE To assess the relationship between breast arterial calcification (BAC) detected on screening mammography and atherosclerosis of carotid arteries considering the most likely involved layer of the arterial wall. MATERIALS AND METHODS A total of 537 consecutive women who underwent screening mammography were enrolled in this study. Seventy-nine subjects having BAC, aged 46-75 years, and...

To determine whether systematic differences exist between hypertensive children referred for evaluation by primary care providers and children identified through community-based screening, cardiovascular risk factors and surrogate markers of hypertensive injury were compared based on subject source (referral versus screening). Children referred to a hypertension clinic for persistently elevated...

Directional continuous wave Doppler ultrasonography has been used to assess the extracranial carotid arteries of over 500 patients, 90 of whom have had angiography performed. The angiographic and Doppler findings are compared, showing that this simple ultrasound technique is able to detect carotid stenosis and occlusion, but is unreliable in the detection of mild atheromatous change. In this se...

Results are presented from a two year prospective study using a Doppler ultrasound technique for the detection of carotid disease. The patients studied presented with transient cerebral ischaemic attacks or small strokes in the carotid territory. No other form of patient selection was used. Results were compared with those from carotid and arch aortography. 86% of normal vessels and 78% of dise...

Opacity Pulse Propagation Measuremen ts in Humans: Atraumatic Screening for Carotid Arterial Occlusion • Opacity pulse propagation times to areas of facial skin supplied by internal carotid (medial supraorbital area) and external carotid arteries (lateral supraorbital areas, cheeks, etc.) were carried out in 27 patients with cerebrovascular symptoms, 16 of whom had normal four-vessel angiograph...

One hundred twenty two patients ahd carotid compression tonography (CCT) followed by bilateral carotid arteriogaraphy. Inthe group (82 patients) which was felt to have significant occlusive disease of internal carotid at the level of carotid bifurcation (smaller than 50 percent stenosis), the CCT showed a 92 per cent correlation with arteriography. Of the group (48 patients) that underwent enda...
