title: Contralateral external carotid-middle cerebral artery bypass for carotid artery resection.
abstract: Resection of the common carotid or internal carotid artery is occasionally unavoidable in cases of advanced head and neck carcinoma with carotid artery involvement. To prevent the consequent decrease in cerebral perfusion, we have developed a contralateral external carotid-middle cerebral artery bypass grafting technique. From 1990 through 1995, six patients with advanced head and neck cancer involving the carotid artery underwent total tumor resection combined with vascular reconstruction using the contralateral external carotid- middle cerebral artery bypass grafting. No bypass-related complications occurred in any patient postoperatively. Cerebral hemodynamics after surgery indicated that this bypass graft worked steadily over a long term and supplied sufficient volume of blood to the cerebral cortex on the opposite side in every case.
