The timing of surgery in patients suffering from subarachnoid hemorrhage grade IV and V according to Hunt and Hess, is still controversial. Several authors advocate early surgery for patients in poor clinical condition. Improved outcome and decreased mortality rates were reported. Others exclude patients in poor condition from early aneurysm surgery. ⋯ Our results favor an aggressive treatment of grade IV aneurysm patients by means of ventricular drainage, early surgery and triple-H therapy.

Intracranial subdural hematoma is an exceptionally rare complication of spinal anesthesia. We report a case of this infrequent event and consider the influence of cerebral atrophy as a predisposing factor. ⋯ Persistence of headache and gradual progression despite treatment must be regarded as a sign of intracranial complication following spinal anesthesia. In this case, cerebral atrophy is considered to be a contributory factor for the development of subdural hematoma following dural puncture.

From 1987-92 in Izumo City, Japan, we diagnosed 123 patients as having subarachnoid hemorrhage (SAH) by computed tomography, autopsy, or surgery (proven SAH); the crude incidence rate was 25/100,000/year for all ages. However, to estimate the actual incidence and mortality rates, we should take into account the decedents who died without confirmation by these methods but were presumed to have died of SAH. ⋯ When including the patients who may have died of SAH, the actual incidence rate of SAH is much higher than that which has been reported to date, and the actual mortality rate is still very high.
