[Primitive trigeminal artery combined with arteriovenous malformation of the brain].

Analysis of the brain circulation and consequences of the intravascular surgery in a woman of 22 with a combined pathology--a primitive trifacial artery with an arteriovenous brain malformation--are presented. The arteriovenous malformation was cured surgically with the use of polystyrene emboli some of which penetrated through the primitive trifacial artery into the branches of carotis interna. The possibilities of the above combinations should be taken into consideration when the method of the intra-vascular surgery is to be chosen.
