title: [Intra operative embolization of unresectable cerebral arterio-venous malformations. Occlusion attempt by means of a delayed polymerization mixture. Report of two cases (author's transl)].
abstract: Two cases of unresectable intra-cranial arterio-venous malformation (AVM) are reported, treated by direct intra-operative embolization. A 50% mixture of Butyl-2-Cyano-Acrylate and Mono-Iodo-Stearate of Ethyle (Duroliopaque) was used after catheterization of some of the feeding cortical arteries. No intra-operative angiography was performed. The first patient, admitted after subarachnoid hemorrhage and presenting with a mild transient right hemiparesia and aphasia, showed evidence of a left temporal AVM with a left middle cerebral artery supply and contribution from the left cerebral posterior artery. The AVM was embolized with 3 cc of the mixture. A mild aphasia occurred after surgery and completely recovered after two weeks. Roughly half of the AVM was occluded on the postoperative angiograms. The second patient suffering from a long history of seizures had a huge right frontal AVM, with a right middle cerebral artery and right anterior cerebral artery supply, and contribution from a right lenticulostriate artery, the left anterior cerebral artery and the right posterior cerebral artery. The AVM was embolized with 7 cc of the mixture. A complete palsy of the left upper limb occurred after surgery, with complete recovery after two weeks. On the post-operative angiograms, more than three fourth of the AVM was occluded.
