ABSTRACT

Occlusion of internal carotid artery is not uncommon; its progression frequently hinders endarterectomy because the thrombus extends into the origin of the ophthalmic artery, making the carotid artery inadequate for reconstruction. The internal carotid only emits intracranial branches, but exceptionally, there is an extracranial branch of the internal carotid that keeps the distal flow to the occlusion and makes the revascularization viable as it occurs in the case described here. This is a 67 years old Caucasian male patient, heavy smoker with a history of dyslipidemia. He went to the doctors because of decreased vision in his left eye and dizzy changes. Vascular US and angiotomography showed occlusion of left internal carotid artery, with distal recanalization and presence of collateral anomalous vessel. The treatment consisted of carotid endarterectomy and reestablishment of the flow to the left internal carotid with preservation of the anomalous collateral vessel with satisfactory recovery. The knowledge of the anatomical variations and a careful surgical technique allow reaching good results in carotid occlusion surgery.
