Abstract

Cerebral hemodynamics associated with ischemic stroke and hemodynamic changes due to reconstructive cerebral vascular surgery were evaluated using positron emission tomography (PET) on 20 ischemia patients who showed symptoms of internal carotid artery territory and five who had reconstructive surgery. Two cases had STA-MCA anastomosis and three had carotid endarterectomy. In patients with chronic ischemia, hemodynamic disturbance appeared in the border-zone areas. On the three carotid endarterectomy cases, the hemodynamic factors showed improvement postoperatively, though no remarkable improvement was found on two cases of STA-MCA anastomosis.
