Temporal and Spatial Changes in Cerebral Blood Flow during Management for Preventing Delayed Cerebral Ischemia after Aneurysmal Subarachnoid Hemorrhage: Serial Semiquantitative Analysis

Cerebral perfusion may change temporally and spatially during the management for preventing the delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage. Regional hypoperfusion refractory to the management might exist, which could impact on the clinical outcome. An additional therapeutic approach targeting on such regions may be required.
