BACKGROUND AND PURPOSE Despite improvements in noninvasive imaging, some patients with contraindications to iodine-based contrast material still require angiography for the evaluation of carotid stenosis. Our aim was to assess the utility of gadopentetate dimeglumine as an intraarterial contrast agent in common carotid angiography. METHODS Twelve patients with suspected carotid artery stenosi...

BACKGROUND AND PURPOSE Patients with a carotid artery stenosis, including those with an asymptomatic or moderate stenosis, have a considerable risk of ischemic stroke. Identification of risk factors for cerebrovascular disease in these patients may improve risk profiling and guide new treatment strategies. We cross-sectionally investigated whether carotid stiffness is associated with previous i...

Using Doppler ultrasonography, we evaluated the frequency and severity of carotid artery stenosis in 261 patients with carotid ischemic strokes, 813 patients with carotid transient ischemic attacks, 500 patients with asymptomatic neck bruits, and 500 controls. Most patients with strokes and transient ischemic attacks had no associated carotid artery disease (55% and 64%, respectively), and such...

i) a case of bilateral stenosis of the internal carotid artery with aneurysm of basilar trunk is reported. 2) via femoral angiography confirmed the diagnosis which is strongly recommended in diagnosing such cases. 3) no surgica l treatment is considered. 4) no similar case has been reported in literature.

BACKGROUND AND PURPOSE The aim of this study was to determine the potential value of carotid artery calcification observed on plain radiographs in patients referred for carotid angiogram in the diagnosis of carotid artery stenosis. METHODS One hundred sixty consecutive patients with suspected carotid artery stenosis underwent both plain radiographs of the carotid arteries and digital subtract...

Background and Purpose: The aim of this study was to determine the potential value of carotid artery calcification observed on plain radiographs in patients referred for carotid angiogram in the diagnosis of carotid artery stenosis. Methods: One hundred sixty consecutive patients with suspected carotid artery stenosis underwent both plain radiographs of the carotid arteries and digital subtract...

Background and Purpose Three different methods for estimating the percentage of reduction in the diameter of the internal carotid artery (ie, stenosis) have been proposed in the literature. Further comparisons of the methods were carried out with the intent of recommending a current standard for determining the percentage of stenosis from angiograms. Methods Angiograms from 112 patients were ob...

Carotid artery stenting (CAS) is a widely used method in prevention of stroke for carotid artery stenosis as an alternative to surgical treatment. Initial studies reveal higher morbidity and mortality rates for CAS than acceptable standards for carotid endarterectomy (CEA). The aim of this study was to compare results in a series of CAS with concurrent risk-matched group of CEA patients. The st...
