Risk of Hemorrhage and Obliteration Rates of LINAC-Based Radiosurgery for Cerebral Arteriovenous Malformations Treated After Prior Partial Embolization

Conclusions: The rate of obliteration after RS in AVM treated after prior partial embolization depends on size as well as Spetzler-Martin grade. The risk of intracranial hemorrhage is not increased after RS and depends on AVM score, size, and volume, as well as on applied single dose.
