Video Summary

Dr. Stark from the University of Miami discusses the changes and outcomes of stereotactic radiosurgery (SRS) for arteriovenous malformations (AVMs) over time. The study analyzed data from the International Gamma Knife Research Foundation from 1988 to 2014. It found that there was a decrease in the margin dose, an increase in the maximum dose, and an increase in the number of isocenters used over time. Overall, there was a decrease in obliteration rates and favorable outcomes due to changes in patient selection and treatment parameters, particularly in treating larger AVMs. The study concludes that improvements in patient selection and dose planning are needed to optimize outcomes.
