Transient neurological deterioration is relatively common after superficial temporal artery-middle cerebral artery bypass surgery for the treatment of moyamoya disease. Evaluation of postoperative cerebral blood flow (CBF) indicated that these symptoms could be associated with hemodynamic alteration. To prevent permanent neurological damage, timely and adequate management of this status is required. However, there is currently no intraoperative evaluation system to predict transient neurological deterioration in the postoperative period. Therefore, in this preliminary study, we evaluated quantitative cortical blood flow using indocyanine green videoangiography, ultrasonic blood flowmeter, and a dedicated software in a case of moyamoya disease. As a result, substantial increase of focal cortical blood flow was calculated by the software. However, no postoperative neurological deterioration was observed, and the postoperative CBF evaluation showed no hyperemia or ischemic status. This system might be useful; however, further evaluation is essential.
