Microsurgery for ruptured intracranial aneurysms in anterior circulation.

Objective: To improve curative effects of microsurgery on the ruptured intracranial aneurysms in the anterior circulation. Methods: Clinical data of 56 patients with ruptured intracranial aneurysms in the anterior circulation, who underwent microsurgery after the rupture, were analyzed retrospectively. Results: There were 61 aneurysms in 56 patients. Of 61 aneurysms, 45 were treated by clipping the neck of aneurysms,6 by resection of aneurysmal body after clipping the neck, and 10 by wrapping. There were hemiplegia in 1 patient because vascular occlusion after the operation 3 day. The following up for 1 month to 5 years showed that of 25 patients,17 were recovered well,2 mildly and severely disabled, 2 dead. Conclusions: The rerupture of aneurysms may be prevented by microsurgery after the rupture which is helpful to preventing and treating cerebraovsascular spasms, in the patients with ruptured intracranial aneurysms in the anterior circulation. Expanding blood volume, elevating blood pressure, dilating vessel with drugs have good effects on cerebrovascular spasms.
