title: Improvement of global cerebral blood flow after STA-MCA bypass in a patient with bilateral occlusion of the internal carotid artery: effect of surgery or natural course?
abstract: A xenon-CT examination was performed on a patient who had received a STA-MCA bypass. Evaluation of cerebral blood flow (CBF) pre- and postoperatively shows a post-operative increase of about 60%. During manual compression of STA, a decrease of 20% was observed so that one third of the total CBF increase could be attributed to anastomosis. The remaining two thirds may originate from the natural collateral circulation.
