Classification of arteriovenous malformation and therapeutic implication

Abstract

Classifications of high-flow arteriovenous malformations (AVM5) have been published in the neurovascular literature and in the peripheral vascular literature. These two classification systems are essentially the same in their angioarchitecture analysis. We propose a new Yakes AVM classification system that includes all AVM angioarchitecture types and those that have not been previously reported in the world's literature. This all-encompassing AVM classification system also recommends endovascular treatment strategies that are curative in that specific AVM classification type. Thus, by analyzing the angioarchitecture of the AVM, the practicing physician can then be guided to specific treatment strategies to permanently treat that AVM type. We describe AVMs as Yakes Type I, Yakes Type II, Yakes Type llla, Yakes Type IlIb, and Yakes Type IV.
