Early Draining Vein Occlusion After Gamma Knife Surgery for Arteriovenous Malformations

Abstract

Although venous structures are considered more radioresistant, endothelial damage accompanied by venous flow stasis might cause early venous thrombosis and premature venous occlusion after radiosurgery for AVMs. In our series, all patients had a favorable outcome except 1 with a fatal hemorrhage.
