title: A review of 102 consecutive patients with intracranial aneurysms in a community hospital in Japan.
abstract: One hundred and two consecutive non selected patients with intracranial aneurysms were reviewed. The incidence of ruptured aneurysm was 17.5 per population of 100,000 per year. The patients were divided into two groups, according to a change of policy that reversed the timing of operations from delayed to early surgery. The overall mortality and occurrence rate of neurological deficits due to vasospasm in patients in Hunt and Kosnik grades I through III were found to be lower during the period with a policy of early surgery. Elderly patients over 70 years old constituted 19% of the cases and those in poor condition (grade IV and V) 31%. These figures in this study are high, which may reflect the fact that these are common problems inherent in the treatment of ruptured aneurysms without patient selection at most community hospitals in the forefront of primary medical care.
