A case of mild internal carotid artery obstruction diagnosed by frontal-artery sign and external carotid carotid-artery sign.

A Penetrating Pellet Jeopardizing Internal Carotid Artery

A case of internal carotid artery occlusion complicating embolization of the external carotid artery system.

A case of visual disturbance by embolization through the external carotid artery (ECA) after internal carotid artery (ICA) occlusion is reported. A 65-year-old female presented left ICA occlusion 14 years ago. She was admitted with acute deterioration of left visual acuity. Ophthalmologically, the retinal central artery was occluded. Cerebral angiography disclosed an irregular wall at the left ...

CT perfusion of the neck: internal carotid artery versus external carotid artery as the reference artery.

Arterial selection for reference time-enhancement curve generation in deconvolution-based perfusion CT (PCT) studies of the head and neck is under-evaluated. This study of 11 patients with confirmed head and neck squamous cell carcinoma demonstrates significant correlation (range, r = 0.85-0.95) between perfusion parameter values derived with internal carotid artery (ICA) as compared to an exte...

Report of a Variation of the Right Common Carotid Artery

Carotid artery is the most important artery that carries the major part of the blood supply to the head and neck. The branching of the common carotid artery usually occurs at the upper edge of the thyroid cartilage. The placement of carotid sinus has also increased its importance in this area. Considering the clinical importance of knowledge about carotid artery variations, this case is reporte...

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...
