Abstract

Cerebral arteriovenous malformations (AVMs) are vascular abnormalities that result in an excessive shunt of blood from the arterial to the venous system. Although there is brain parenchyma between the vascular channels of an AVM, it is often scarred and abnormal. The purpose of this study is to measure the elasticity of feeding vessels from AVMs obtained at the time of surgical resection. Pressure measurements of feeding arteries and draining veins of AVMs made prior to surgical resection and reported in the literature are reviewed. By combining the results of the in vivo experiments with published observations of pressure in vivo, a theory of how AVM hemodynamics can change over time is proposed.
