[Microsurgical treatment of cerebral arteriovenous aneurysm]

The authors describe a group of 9 patients with arteriovenous malformations of the brain operated upon using the microsurgical technique and controlled arterial hypotension. In all cases the malformations were radically removed. In one patient the neck of a coexistent aneurysm of the pericallosal artery was clamped with a clip. Disability in one patient was the effect of haemorrhage, another patient with hemiparesis is being rehabilitated. The remaining patients are feeling well and in only one of them epileptic seizures remained after the operation, they had, been however, present before the operation. The use of the microsurgical technique makes possible reduction of the surgical trauma to the brain tissue and opens greater possibilities of intraoperative evaluation of radical performance of the operation.
