Outcomes of single-session gamma knife radiosurgery for deep-seated arteriovenous malformations.

Background: Deep-seated arteriovenous malformations (AVMs) pose unique surgical challenges due to their proximity to critical structures. Gamma knife radiosurgery (GKRS) thus serves a promising alternative that may reduce treatment-related morbidity of deep-seated AVMs. However, the efficacy of GKRS in achieving obliteration in deep AVMs is not established.
