Clinical outcomes following cyberknife radiosurgery for cerebral arteriovenous malformations: A systematic review and meta-analysis.

The median time to achieve complete obliteration was 36 months.

The pooled rate of post-CKRS hemorrhage was 5% (95% CI: 0.01 _ 0.09), whereas the incidence of post-CKRS neurological deficits was 17% (95% CI: 0.09 _ 0.26).

Subgroup analysis for 5 studies based on Spetzler-Martin (Spetzler-Martin) grade revealed a significantly higher obliteration rate for grades I-III (69.92%, 95% CI 64.3-75.5%) than for grades IV-VI (34.3%, 95% CI 25.1-43.5%).
