Stroke from an External Carotid: Lesion Pattern and Mechanisms

Annals of Vascular Surgery
Kagan NicolasMartinez Robert

Abstract

Traditionally, patients with symptomatic external carotid stenosis present with neck or face pain, retinal ischemic symptoms or jaw claudication and rarely as ipsilateral cerebrovascular events. In this present case, our patient suffered a stroke from a paradoxical embolism from the external carotid, without involvement of the internal carotid artery. A plaque ulceration of the external carotid's origin was the cause of this cerebral emboli. Duplex ultrasound showed a pathologic left external carotid, with a floating thrombus in the internal carotid. The diagnostic was confirmed by a computerized tomography scan. An external carotid thromboendarterectomy was performed 6 days after symptom onset, and intraoperative findings confirmed the plaque rupture with an extensive clot in the carotid bifurcation.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
