Angiearchitecture of Brain Arteriovenous Malformation and its Clinial Correlation
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.
