E-039 Comparison of predictive grading systems for procedural risk in endovascular treatment of brain arteriovenous malformations - analysis of 104 consecutive patients

Conclusion Our independent analysis of 104 patients with brain AVMs treated with endovascular embolization validates the predictive capacity of the Buffalo score, but not AVMN or SM grades, for endovascular embolization procedural risk. This will allow for better stratification of brain AVM patients by procedural risk, and will ultimately result in safer care of these patients.
