    Journal: Eur J Radiol; 2012 Apr; 81(4):780-3. PubMed ID: 21334838.
    Abstract:
    OBJECTIVE: To explore angioarchitectural features of brain arteriovenous malformations (BAVMs) in ages. METHODS: 302 Consecutive patients with BAVMs between 1999 and 2008 were retrospectively reviewed. Univariate analysis was used to test initial presentation and BAVM characteristics in different ages. RESULTS: Patients ranged in age from 5 to 65 years (mean±SD, 28.3±12.8). One hundred and eighty-eight were male and 113 female. Clinical presentations were hemorrhage (52.6%), seizure (24.5% of patients), headache (12.6%), focal neurological deficit (6.3%), or other clinical events, including incidental BAVM diagnoses (4.0%). Increasing age correlated positively with coexisting arterial aneurysms (P=0.044). No differences were found for sex, initial presentation, BAVM size, BAVM location, arterial feeders and venous drainage pattern between each age groups. CONCLUSION: Increasing age correlated positively with coexisting arterial aneurysms. No statistical significance was observed for clinical presentations, and BAVM characteristics among age groups.
