Objective: To explore angioarchitectural features of brain arteriovenous malformations (AVMs) manifesting with hemorrhage and without hemorrhage. Methods: During the period 1999–2008, 302 consecutive patients with AVMs were retrospectively reviewed. Univariate and multivariate logistic analysis was used to assess AVM characteristics in patients who presented with hemorrhage and patients who presented without hemorrhage. Annual and cumulative incidence rates of AVM rupture were analyzed using Kaplan-Meier life-table analyses. Results: The annual risk of hemorrhage from AVMs in this study was 1.9%. In the comparison of 159 patients with AVM with hemorrhage at initial presentation with 143 patients who did not experience hemorrhage initially (total 302 patients), deep…
