Risk factors of hemorrhagic brain arteriovenous malformation / 中国介入影像与治疗学

ABSTRACT

Objective To analyze risk factors of hemorrhagic brain arteriovenous malformation (BAVM).Methods Totally 105 BAVM patients confirmed with DSA were collected,and corresponding risk factors were analyzed.Results Univariate analysis suggested that factors were correlated to hemorrhagic presentation including the site and size of the lesions,the type and number of feeding arteries,the number,type and form of draining veins and co-existing arteriovenous fistula.Multiple factors Logistic analysis showed that the location,size,the type and amount of supplying arteries,the number of the draining vein and combined with arteriovenous fistula were the risk factors for hemorrhagic presentation,and drainage vein dilation might be a protective factor.Conclusion Infratentorial and deep cerebral lesions,arteriovenous malformation with diameter ＜3 cm,single draining vein,pure perforating artery,multiple feeding arteries and combined with arteriovenous fistula are risk factors for hemorrhagic BAVM.
