Review of aneurysmal subarachnoid hemorrhage--focus on treatment, anesthesia, cerebral vasospasm prophylaxis, and therapy.

Aneurysmal subarachnoid hemorrhage (aSAH) is a serious and debilitating condition that leads to the development of many complications, which are followed by mortality and morbidity. As anesthesiologists, we may require to manage aSAH at various settings such as in the perioperative period or in a nonoperative setting such as the neuroradiology suite for diagnostic and therapeutic interventions. Therefore, it is important to understand the pathophysiology of aSAH and anesthetic management for operations and interventions. For decades, early brain injury and cerebral vasospasm have played major roles in the outcome following aSAH. The purpose of this article is to review recent advances and future perspectives in the treatment of aSAH, early brain injury, and cerebral vasospasm.
