ABSTRACT

Objective To analyze the relevantly risk factors of cerebral arteriovenous malformation (AVM ) with hemorrhage . Methods The clinical data of 127 patients with cerebral arteriovenous malformation were retrospectively analyzed .71 patients with hemorrhage were divided into the hemorrhage group while 56 patients without hemorrhage were divided into the control group .The clinical data of the two groups were compared and analyzed .Results Univariate analysis indicated that the differences of location and size of the AVM masses ,location of the feeding arteries ,direction of the draining vein ,combining with aneurysms and size of aneurysms were statistically significant (P1) .Conclusion The patients with deep AVM masses ,small-sized AVM masses(<3 cm) ,deep draining veins and combining with aneurysms should be operated as soon as possible to avoid hemorrhage .
