[Temporary arterial clipping in surgery for cerebral aneurysms in acute subarachnoidal hemorrhage].

Temporary clipping was used during operations in 69 patients. Of them, 51 patients underwent temporary arterial clipping, forced temporary arterial clipping was used in 18 patients. A total of 104 patients were operated on with preventive temporary clipping. Aneurysmal rupture occurred in 18 (17.3%) patients of them. The bioelectrical activity of the brain was intraoperatively monitored by using EEG and ECG in 12 patients of whom 11 felt rather well on discharge. The temporarily arterial clipping technique using EEG and ECG makes it possible to monitor the allowable time of temporary arterial clipping, which is in turn associated with a less risk for postoperative ischemic complications.
