A 78-year-old man presented with recurrent left hemispheric transient ischaemic attacks. Angiography-wise and intraoperatively extreme internal carotid artery (ICA) coiling was noted with critical stenosis (Figs 1 and 2A). ICA bulb was transected, plaquebearing segment resected and ICA reimplanted onto endarterecomized carotid bifurcation (Fig. 2B). At 1-year follow-up, he is symptom-free with ...

PURPOSE To assess the accuracy of MR angiography alone in screening for vascular stenosis of the common carotid bifurcation. METHODS Two hundred two common carotid bifurcations in 101 patients were evaluated with MR angiography and selective contrast arteriography. A two-dimensional time-of-flight pulse sequence was used to obtain sequential transverse images through the common carotid bifurc...

BACKGROUND AND PURPOSE Conventionally, carotid ultrasonography has been performed with a 7.5-MHz linear probe to evaluate the extracranial internal carotid artery (ICA). However, usually only the carotid bulb or proximal portion of the ICA can be evaluated. We attempted to evaluate the distal extracranial ICA with a 3.5-MHz convex probe. METHODS The subjects were 17 consecutive patients with ...

INTRODUCTION The geometry of the carotid bifurcation has been proposed as a possible risk factor for atherosclerosis, by virtue of the purported role of local hemodynamics in early stages of atherosclerotic plaque development [1]. In this context it is of interest to study asymptomatic subjects with mild carotid artery disease. Instead, investigations of carotid bifurcation geometry and hemodyn...

Contrast-bolus tracking in the carotid bifurcation was accomplished using an MR angiographic technique with a 3D turbo field-echo readout (TR/TE = 6/3, flip angle = 50 degrees) modified by a keyhole scheme. Optimal visibility of the contrast bolus was achieved by digital subtraction from a reference volume. This technique reliably time-resolves the carotid arteries from the jugular veins.

A 32 year old female with hyperprolactinaemia-galactorrhoea-amenorrhoea due to a right internal carotid artery aneurysm just before its bifurcation is described. She had two episodes of subarachnoid haemorrhage necessitating an emergency internal carotid artery ligation. She responded to bromocriptine treatment with restoration of her menses, normalization of circulating prolactin and disappear...

We report a case of a 79-year-old man presenting with left cervical carotid artery stenosis associated with non-bifurcating cervical carotid artery, a very rare congenital anatomical variation supplying different branches of the external carotid artery directly from a common trunk without a bifurcation. We performed carotid endarterectomy for this symptomatic carotid artery atherosclerotic sten...

Correspondence To the Editor: Carotid body tumor (CBT) is a highly vascular neoplasm of neural crest origin arising in paraganglial cells of the carotid bifurcation. Branches from external carotid artery or glomic artery arising at the bifurcation of common carotid artery dominate in the blood supply mode. Only very few cases with supplementary blood supply from an internal carotid artery (ICA)...
