During the past half century, major developments in surgical techniques, diagnostic methods, anesthesia, and adjunctive treatments in the care of patients with subarachnoid hemorrhage (SAH) have been achieved. For instance, the microsurgical techniques by the use of an operating microscope has greatly increased the ease and safety of the direct attack to a ruptured aneurysm. The recent invention of computed tomography (CT) scan has greatly contributed to evaluation of amount and distribution of subarachnoid blood, brain damage due to intra-cranial hematoma, brain edema, infarction, hydrocephalus, and so on, thus enabling an exact judgement as to the feasibility of operative interventions and the prognosis of patients. The use of hypertonic solutions and neuroleptic drugs combined with advanced cardiorespiratory controls during anesthesia markedly decreased the hazards encountered in aneurysm operations.
