Hydrodynamic calculations for embolization strategy of cerebral arteriovenous malformations with fistulous component

Various scenarios of cerebral arteriovenous malformation (AVM) embolization were considered by using a locally developed mathematic model of vascular malformation as a set of different diameter tubes. It was demonstrated that the least pressure drop at the AVM inlet could be achieved by embolizing the widest fistula first and then large and small compartments of AVM. A comparison of model calculations with the results of AVM embolization in 15 patients was performed.
