ABSTRACT

PURPOSE:

To evaluate the different angio-architectures of brain arteriovenour malformatigns (AVMs) accordingto 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 MF ratio was 13678 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 andnon-hemorrhagic groups. Angiograms were analyzed by two radiologists for the size and location of nidus; thenumber of feeding arteries and the extent of aneurysm, stenosis, dural supply, and angiomatous change; the numberof draining veins and the extent of deep or superficial drainage, stenosis, ectasia, kinking, and stasis. Thestandard 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 nidusof 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 symptomaticpresentation. Analysis of the patterns of angioarchitectureis useful for prognosis and in deeiding the direetionof freatment.
