Abstract

The endovascular approach is the standard treatment of vein of Galen malformations (VOGMs,) however the morbidity and mortality rates of VOGMs treated by embolization are still significant. Embolization with ethylene vinyl alcohol copolymer (EVOH) by a dual-lumen balloon (DLB) is a promising. In the present case we demonstrated two strategies of transarterial (TA) embolization of a mural type VOGM presenting with two direct shunts. The first shunt was embolized using coils to reduce the flow through the shunt, following by an EVOH injection which resulted in the complete occlusion of that shunt. The second shunt was embolized also with EVOH but through a DLB. In the second embolization a very precise cast of EVOH could be created resulting in a complete occlusion of the VOGM. This case demonstrated the advantages of DLB compared to other embolization techniques
