Abstract
A series of 162 arteriovenous malformations (AVM) surgically removed is reported. All patients had a post operative control angiogram showing that the lesion was totally excised. Supra and infra tentorial AVM are included in the series as well as conscious and comatous patients. The overall mortality was 11.1% and the mortality in conscious patients was 6.9%. Mortality is higher when the volume of AVM is over 60 cm3 and when a rupture has occurred. The influence of the operation on epileptic seizures, motor, speech or visual fields deficits was reviewed in 109 patients who answered to the survey. Morbidity was higher in patients with a cerebral hemorrhage, an operation in these patients before the rupture when, for instance, seizures represents the only clinical picture. C.A.T. (computed axial tomography) scan in these epileptic patients is a useful way to track down AVM.
