Spetzler-Martin Grading System

The Spetzler-Martin Grading System is a method used to classify brain arteriovenous malformations (AVMs), which are abnormal tangles of blood vessels in the brain. This system assesses three key factors: the size of the AVM, its location in the brain, and the presence or absence of associated neurological deficits. Each factor is assigned a score, helping doctors determine the risk of surgery and the likelihood of successful treatment. The grading helps guide decisions about managing AVMs effectively, optimizing patient outcomes while minimizing risks during potential interventions.
