Intracranial aneurysms in the neurosurgical clinics in Japan

Abstract

✓ To study the current state of intracranial aneurysms in the neurosurgical clinics in Japan, simple questionnaires were sent to 112 institutions in December, 1969, and answers were obtained from 111. The following questions were asked: The total number of cases and aneurysms; the age and sex; the site and side; and the anesthesia and treatment used. These statistical studies have been compared with those of the cooperative study on subarachnoid hemorrhage in the United States.
