Spetzler-Martin grading scale

The Spetzler-Martin grading scale is a system used by doctors to evaluate brain arteriovenous malformations (AVMs), which are abnormal tangles of blood vessels in the brain. This scale assesses three key factors: the size of the AVM, its location in the brain, and whether it has caused any neurological deficits. Each factor scores points, and the total score helps classify the AVM as low, moderate, or high risk for treatment. This grading helps guide doctors in deciding the best approach for management and treatment, balancing risks and benefits for the patient.
