[Super-selective angiography: analysis of angio-architecture and embolization of cerebral arterio-venous malformation].
The angiograms of cerebral arterio-venous malformation (AVM) were analysed through 198 super-selective procedures. The AVM nidus as a whole can be classified as: single supply artery and multi-drainage veins; multi-supply arteries and single drainage vein; multi-supply arteries and multi-drainage veins. Angioarchitecture was divided into five types: terminal supply, penetrating supply, A-V shunt, combined with aneurysm and with anomalous venous structure. Supper-selective angiography was also used for regional functional test and A-V circulation time calculation, as a correct guidance for embolization treatment.
