Common Carotid Artery Occlusion Presenting with Recurrent Syncopal Episodes
نویسندگان
چکیده
Symptomatic common carotid artery (CCA) occlusion is an uncommon occurrence that may require surgical intervention. We aim to describe a case of CCA occlusion that presented with the unusual symptom of recurrent syncope. A 69-year-old lady presented with a history of recurrent syncopal episodes and amaurosis fugax associated with left leg weakness. She was found to have a right CCA occlusion on duplex ultrasound and angiography. She underwent a right common carotid endarterectomy and intraoperative findings revealed a heavily calcified plaque in the CCA just proximal to the bifurcation with organised thrombus filling the CCA proximally. CCA occlusion can rarely present with recurrent syncopal episodes. Surgery may be curative.

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...

BACKGROUND Syncope is commonly worked up for carotid stenosis, but only rarely attributed to it. Considering paucity of such cases in literature, we report a case and discuss the pathophysiology. DESIGN/METHODS We report a patient with high-grade bilateral severe internal carotid artery (ICA) stenosis who presented with syncopal episodes in the absence of stroke, orthostatic hypotension, sign...
