Methods Two hundred and seventy-one patients with cerebral arteriovenous malformations were followed up. There were 2 81 clinical follow-up cases, 91 cerebral angiography findings and 1 90 MR or CT examinations. Results A total of 2 81 cases were followed up and cured, with 21 cases being improved and 2 cases relapses. Cerebral angiography was performed in 91 patients. Totally 86 deformities disappeared completely. Three embolisms were over 90%. Two patients relapsed and were cured after γ knife radiotherapy. 1 90 cases of MR or CT examination, no recurrence. Conclusion Endovascular embolization is a safe and effective treatment for cerebral arteriovenous malformations
