[Surgery of aneurysms of the cerebral arteries--results and problems]

Surgery has been performed on 100 intracranial aneurysms during the past seven years. Of these, 96 involved the application of microsurgical techniques and could definitely be clipped. Lethality was 8%. Post-surgical deterioration of the clinical neurological status was observed in another 20 patients, but vanished subsequently in 16 of them. Immediate surgery within 48 hours of the subarachnoidal hemorrhage is recommended to avoid subsequent hemorrhage and prevent severe vasospasmic phenomena. Only patients whose general status is good (Hunt and Hess degree 1 or 2) are suitable for immediate surgery.
