[Method of total removal of cerebral arteriovenous aneurysms].

In an attempt to improve the results of total removal of arteriovenous aneurysms from the brain the authors have been using an operation microscope and microsurgical technique for the recent 5 years. This permitted to leave the minimal number of clips on the main afferent arteries and large drainage veins of the aneurysm, thus decreasing the risk of the development of gross connective tissue capsules around the silver clips, and of the inherent disorders in the brain function. In 20 patients 2 to 8 clips were left in the brain after surgery. Nineteen patients were discharged from the clinic with improvement, or without any changes in their preoperative neurological symptoms. Two patients died. Rare epyleptic fits were observed only in one patient.
