PURPOSE To evaluate patients with high-risk cerebral arteriovenous malformations (AVMs), based on eloquent brain location or large size, who underwent planned two-fraction proton stereotactic radiosurgery (PSRS). METHODS AND MATERIALS From 1991 to 2009, 59 patients with high-risk cerebral AVMs received two-fraction PSRS. Median nidus volume was 23 cc (range, 1.4-58.1 cc), 70% of cases had nidus volume ≥ 14 cc, and 34% were in critical locations (brainstem, basal ganglia). Median AVM score… CONTINUE READING
