Abstract

A retrospective clinical study was performed in 41 patients with intracranial AVM during the period from January 1985 to December 1989. 12 patients managed conservatively and 29 patients surgically were followed for an average of 15 months. The results were as follows ; 1) The age range of presentation of intracranial AVM was 5 years to 48 years, with peak incidence from second to third decade. 2) The presenting symptoms and signs were intracranial hemorrhage(75.6%), seizure(12.5%), and headache(9.7%) in order of frequency. 3) In intracranial hemorrhage, intracerebral hematoma was the most frequent. 4) In small intracranial AVM, 84.2% was presented with hemorrhage, and large intracranial AVM, 37.5% with seizure. 5) There was a correlation between AVM grade of Spetzler & Martin and the incidence of postoperative neurological complication. 6) The clinical outcome for patients managed surgically was more favorable than that for patients managed conversatively.
