Abstract:
The authors studied angiographic features in relation to risk of hemorrhage in 102 cerebral arteriovenous malformations(AVM;s). Statistical analysis demonstrated that AVM's with following characteristics had high risk of hemorrhage : 1) small nidus ; 2) deep, posterior fossa, cortico-callosal, cortico-ventricular location ; 3) one or two draining veins ; 4) deep venous drainage ; 5) high grade stenosis of major venous drainage. The authors suggest that as the venous drainage system is significantly associated with the risk of hemorrhage in AVM's, careful preoperative angiographic evaluation of the venous drainage system is mandatory for decision making in the management of patients with AVM's.
