AVMs smaller than 3cm in diameter with deep draining veins throughout the eloquent cortex are perfect for stereotactic radiosurgery because the morbidity and mortality of open surgical resection of those lesions are the very best. Stereotactic radiosurgery (SRS) can obtain a 70% to 90% obliteration rate in correctly selected people.
