Purpose : To evaluate the different angio-architectures of brain arteriovenour malformatigns (AVMs) according to the presence of non-hemorrhagic symptoms or intracerebral (ICH) and/or intraventricular hemorrhage(IVH).Materials and Methods : The results of complete cerebral angiography obtained in 215 patients with AVM between1989 and 1994 were retrospectively reviewed. The M:F ratio was 136:78 and their mean age was 29 (ranged 4 - 66)years. On the based of clincal presentation, CT and/or MR images, they were divided into hemorrhagic and non-hemorrhagic groups. Angiograms were analyzed by two radiologists for the size and location of nidus; the number of feeding arteries and the extent of aneurysm, stenosis, dural supply, and angiomatous change; the number of draining veins and the extent of deep or superficial drainage, stenosis, ectasia, kinking, and stasis. The standard chi-square test was used for statistical analysis.Results : Hemorrhage was noted in 140 patients(65%),and no hemorrhage in 75(35%). Hemorrhage was more common in AVM with deep-seated and callosal locations, a nidus of less than 2cm, single feeder and single venous drainage, and deep venous drainage only (p < 0.05 - 0.001).Non-hemorrhagic presentations were more common in AVM with cortical and subcortical location, a nidus of more than5cm, angiomatous change, dural supply, both superficial and deep venous drainage, kinking, and stasis (p <0.05-0.001). Conclusion : The angio-architechture of AVM with hemorrhage correlated with clinical symptomatic presentation. Analysis of the patterns of angioarchitectures useful for prognosis and in deciding the direction of treatment.
