| ABSTRACT |
|
Among 51 intractanial AVM patients, 30 patients(58.8%) with AVM supplied mainly with PCA were studied for the relationship with feeding vessels, location and the size of AVM in connection with hemorrhage and also results in 20 surgical patients were analyzed. On cerebral angiogram, 56.7% accounted for AVM supplied only by PCA, 16.7% together with MCA and 26.6% with MCA and ACA. By location, 36.7% were for subcortical AVM and 63.3% were for deeply located paraventricular. 53.3% were large AVM and of them, 6.5% bleeded 30.0% accounted for small AVM, of which 88.9% bleeded. The total bleeding rate was high at 73.3%. Complete removal by surgery was available for 90.0%, and post operative improvement was at 75.0% with a mortality rate of 10.0%. 50.0% showed disappearance of seizure following total removal and 33.3% improved. 5.0%, however, had seizure for the first time following the surgery. |
