Abstract

Arteriovenous malformation of the brain is a congenital abnormal communication between arterial and venous channels without the interposition of the capillary system. A retrospective clinical study was performed on 20 patients with supratentorial arteriovenous malformation during the period from September 1984 to December 1986. The 20 patients were underwent surgical treatment using the operating microscope. Followings are the results: 1) The age range of presentation of supratentorial AVM(arteriovenous malformation) was to be from 30 months to 64 years, with peak incidence of fourth decade. 2) The presenting symptoms were hemorrhage, change of consciousness, seizure, headache in order of frequency. In hemorrhage, intracerebral hematoma was the most common type. 3) The most common sites of supratentorial AVM were frontal and parietal lobe. Most of the supratentorial AVM were fed by branches of the middle cerebral artery. 4) Computerized tomographical findings of AVM were intracerebral hemorrhage and mass effect. And after injection of contrast medium, 13 out of 20 AVM showed strong enhancement. 5) After operation, 13 patients were regained nearly total function.
