Abstract: Objective: To explore the relationship between angioarchitectures of cerebral arteriovenous malformations(AVM) and hemorrhage and to reveal the risks of bleeding. Methods: Aortocranial angiography was taken for 200 patients by digital subtraction angiography（DSA）, and then the feeding artery of AVM, the malformation vessel corps, and the draining veins were searched. Bleeding ratios of patients with different angioarchitectures were compared. Results: AVMs feeded by perforators, located in the basal ganglia and post cranial fossa, with small size, exclusively deep drainage, venous stenoses and complicated aneurysms were more likely to present with hemorrhage. Conclusion:　The hemorrhage of AVM is significantly concerned with many factors, such as the type of feeding artery, size and location of the AVM, the draining vein and complicated aneurysms or not.

Key words: Cerebral arteriovenous malformation, Hemorrhage, Angio-architecture
