Classification of Spontaneous Dural Arteriovenous Fistulas with Regard to Their Pathogenesis

Abstract

The morphological development of DAVFs seems to depend on the flow volume of the venous recipient. A pronounced development of pathological AV shunts takes place at the level of the large basal dural sinuses. A delayed development of pathological AV shunts with a low shunt volume occurs in a venous recipient with a low AV pressure gradient.
