Liquid Biopsies for Detecting Somatic Mutations in Sporadic Cerebral Arteriovenous Malformations.

"This research aims to evaluate the genetic mutations identified by liquid biopsies on the drainage vein of AVMs, and the prevalence of each mutation.~These liquid biopsies will be performed during the embolisation procedure by sampling the drainage vein of the malformation and peripheral venous blood (no additional procedures compared to standard care)."
