ABSTRACT
Objective To study the angiographic characteristics of congenital intracranial dural and cerebral arteriovenous malformations, and their relationship to the structural characteristics and clinical feature. Methods The clinical histories, cerebral angiograms, and endovascular treatment of 52 cases of the dural and cerebral arteriovenous malformations were analyzed. Results All 52 patients were treated successfully with interventional therapy with introduction of intravascular emboli through microcatheters. In 2 patients, surgical excision was performed after embolism. In another 4 patients, X-ray knife treatment was carried out. Seventeen patients resumed their work, comprising 44.7% of all patients, and in 16 patients symptoms of epilepsy or head ache were markely improved, comprising 42.1% of the group. Conclusion It is important to study structural characteristics with angiograms for successful treatment of congenital artero-venous anomalies of the brain. [HS(1*2/3]
