Abstract:
PURPOSE: To analyze angiearchitecture of arteriovenous malformations(AV malformation) in order to clarify the angiegraphic risk factors for intracerebral hemorrhage and other nonhemorrhagic symptoms. MATERIALS AND METHODS: Eighty-five patients with angiegraphically-proved brain arteriovenous malformation were included in this study. Retrospective review of clinical history and angiography was done. Topographic analysis and evaluation of 17 angiearchitectural characteristics were conducted. RESULTS: Deep-seated and cortico-callosal type, small nidus size, intranidal pouch, one draining vein, deep venous drainage only venous stenosis and venous aneurysm were the most discriminating or predictive characteristics of hemorrhage in brain arteriovenous malformation. And those with large nidus size, dural supply and venous hypertension were correlated with nonhemorrhagic symptoms such as seizure, headache and neurologic deficit. CONCLUSION: Detailed analysis of the angiearchitecture of brain arteriovenous malformations is needed to identify the features that are correlated with prognostic implications for the treatment of patients with ^V malformations.
