EXTERNAL CAROTID ARTERY PLAQUE INDEPENDENTLY PREDICTS MORTALITY IN PATIENTS WITHOUT INTERNAL CAROTID ARTERY ATHEROSCLEROSIS

A Penetrating Pellet Jeopardizing Internal Carotid Artery

Amount of smoking independently predicts carotid artery atherosclerosis severity.

BACKGROUND AND PURPOSE Cigarette smoking is correlated with extracranial carotid artery plaque thickness. Our aim in the present study was to determine whether the level of prior cigarette use is a significant predictor of carotid artery plaque thickness when age, history of hypertension, and history of diabetes are controlled. METHODS We studied a continuous sample of 790 patients with a his...

Anomalous External Carotid Artery-Internal Carotid Artery Anastomosis in Two Patients with Proximal Internal Carotid Arterial Remnants

Two angiographic instances of anomalous external carotid artery (ECA) and internal carotid artery (ICA) anastomosis are described, each occurring at the C2-3 level and bearing remnants of proximal ICA. The ICA remnant of one patient (identifiable immediately upon bifurcation of the common carotid artery) was hypoplastic, and that of the other patient was an occluded arterial stump. These featur...

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...

External carotid artery in internal carotid artery occlusion. Angiographic, therapeutic, and prognostic considerations.

Twenty-three instances of internal carotid artery occlusion occurring with minimal neurological deficit in 22 patients are described. Although each of these patients was referred to the neurosurgical service for evaluation for an extracranial-intracranial microvascular bypass procedure, complete arteriographic evaluations of their cerebrovasculature suggested that alternative methods should be ...
