Video Summary

In this video, neurosurgery resident Jeffrey Appelbaum discusses the results of a comparison of grading scales for radiosurgery in pediatric patients with arteriovenous malformations (AVM). AVM is a rare disease with potential disastrous outcomes due to bleeding, volume, location, and age. The treatment modalities include endovascular treatment, microsurgery resection, and radiosurgery. The study compares different grading scales for AVM and evaluates their predictive ability for obliteration, functional outcome, and composite outcome. The Pollock-Flickinger and PARAS scales were found to be better at predicting obliteration and excellent outcome. Appelbaum suggests that more studies are needed, especially in the pediatric population, and that the scales should consider factors like volume and depth.
