Abstract

We have reviewed 37 non-surgical cases of arteriovenous malformation (AVM), and analyzed several factors affecting bleeding and outcome. The risk of re-bleeding was higher in the cases with bleeding than in the cases without bleeding. Deep-seated AVM's seemed to have a somewhat greater tendency to bleed than those located superficially. Bleeding and location of the nidus seemed to be responsible for the mortality. The outlook for a patients with an infra-tentorial AVM was worse than for a supratentorial AVM. The outlook for a patients with a deep-seated AVM was worse than for a superficially located AVM. Spetzler grade of the AVM was not significantly related to the outcome of the non-surgical cases.
