Conclusion:

We conclude that Linac-based stereotactic radiosurgery is safe and effective noninvasive treatment modality for AVM. Factors such as age, fraction size, PTV volume and AVM score has an impact on achieving better obliteration rate with minimal toxicity.

Keywords: AVM grading score, Linac based radiosurgery, AVM
