The most serious and frequent complication of intracranial arteriovenous malformations(AVMs) is intracranial hemorrhage. To identify clinical and angiographic characteristics of AVM which positively correlates with hemorrhagic presentation, we retrospectively analyzed 61 consecutive cases with intracranial AVMs. The following charateristics correlated positively with hemorrhagic presentation of AVMs male sexuality(P=0.059, borderline significance), history of hypertension(p<0.05), nidal dimeter<3cm(p<0.05), deep venous drainage(p<0.05), presence of intranidal aneurysm(P<0.05). Detailed analysis of the clinical and angiographic factors associated with risk of bleeding from AVMs may be the important prognostic implications for the treatment of patients with these leions.
