Multiple Variations in Carotid Arteries: Lower Common Carotid Bifurcation, Hypoplastic and Tortuous Internal Carotid Artery

Carotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion

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...

A Penetrating Pellet Jeopardizing Internal Carotid Artery

Catheterization of tortuous carotid arteries.

Not uncommonly, when cerebral angiography is performed via the femoral route , a long flexible-tip guide wire may be introduced into the appropriate vessel , but because of tortuosity of the carotid artery the catheter does not follow the guide wire. During attempts to maneuver the catheter into the carotid artery, the catheter and guide wire are displaced into the aortic arch . To overcome thi...

Carotid artery thrombosis and cerebral infarction after multiple traumas

Carotid artery thrombosis and concomitant brain infarction after blunt trauma are rare conditions. We report a 34-year-old woman with multiple traumas due to pedestrian car accident. At the time of initial visiting, she was somnolent and her Glasgow coma scale (GCS) score was 14. Initial vital signs (V/S) and brain computed tomography (CT) scan were normal. One day after admission to the emerge...

Anatomical variations of the common carotid artery bifurcation.

BACKGROUND The correlation of the common carotid artery (CCA) bifurcation and its surrounding structures is poorly described. The aim of this study was to describe the anatomy of the CCA bifurcation relative to its surrounding structures. METHOD We dissected a total of 67 carotid specimens from 36 embalmed cadavers. CCA bifurcation occurred at the superior border of thyroid cartilage in 39% a...
