Abstract

Information concerning the effectiveness of superficial temporal artery to middle cerebral artery (STA-MCA) anastomosis on cerebral blood flow (CBF) and its CO2 reactivity is still limited and incomplete, and an objective assessment of the postoperative effects on cerebral hemodynamics of the procedure in inaccessible occlusive carotid artery disease is needed. In this study, our initial experience concerning the pre- and postoperative CBF measurements, together with CO2 reactivity in patients undergoing STA-MCA anastomosis, is reported.
