title: Duplication of the internal carotid artery presenting with severe atherosclerotic stenosis.
abstract: Duplication of the extracranial internal carotid artery is a rare anatomic variant. We present the first patient with unilateral duplication of the cervical internal carotid artery with severe stenosis. Stent-assisted percutaneous transluminal angioplasty was successfully performed to restore blood flow. We discuss the angiographic findings and endovascular treatment.
