The cumulative recurrence rate of SAH, calculated using the Kaplan-Meier method, was 2.2% at 10 years and 9.0% at 20 years after the original treatment.Ĭonclusions-The recurrence rate was considerably higher than the previously reported risk of SAH in the normal population, and the rate increased with time. In addition, 2 patients were found to have regrowth of the originally operated aneurysms.
Results-Six patients (2.7%) had recurrent SAH, each with an interval ranging from 3 to 17 years (mean, 11 years) since the original treatment. The mean follow-up period was 9.9 (range, 3 to 21) years. All patients were traced until January 1998 for recurrent SAH or death. Methods-Of 425 patients with SAH surgically treated in Aizu Chuou Hospital from 1976 to 1994, 220 cases meeting the following criteria were studied: (1) all aneurysms detected by 3- or 4-vessel cerebral angiography were clipped, (2) complete obliteration of aneurysm(s) was confirmed by postoperative angiography, and (3) the patient survived >3 years. However, it is still unclear how great a risk of recurrence patients with a successfully treated aneurysm carry over a long-term period.
