title: Bypass surgery for occluded internal carotid artery revascularized by vasa vasorum--case report.
abstract: A 47-year-old woman presented with two transient ischemic attacks due to occlusion of the left internal carotid artery. The affected artery was revascularized by vasa vasorum. Angiography showed occlusion of the left common carotid artery including the origin of the internal carotid artery. The distal internal carotid artery was revascularized by vasa vasorum at the level of the second cervical vertebral body. Left subclavian artery-internal carotid artery bypass surgery using a saphenous vein graft was performed successfully, during which the narrowed but patent lumen of the internal carotid artery was confirmed. Follow-up angiography showed enlargement of the left internal carotid artery distal to the patent bypass. Reconstructive bypass surgery is a possible treatment for patients with occluded internal carotid artery revascularized by vasa vasorum. Angiographic detection of the lumen of the internal carotid artery is important for surgical consideration.
