title: Surgical management of unruptured asymptomatic aneurysms.
abstract: The natural history of unruptured asymptomatic aneurysms in nuclear. Because of this uncertainty regarding risk of ultimate enlargement  and/or hemorrhage, and in view of the significant mortality and morbidity traditionally involved in aneurysm surgery, clinicans have varied in their advocacy of surgical management of such lesions. Forty-nine consecutive patients harboring 52 such aneurysms were treated surgically over a 57-month period. There were no surgical deaths and morbidity was within acceptable limits. Patient population characteristic and surgical technique are discussed.
