Brain AVM classification

Brain AVMs (arteriovenous malformations) are abnormal tangleings of blood vessels in the brain, classified based on their size, flow, and structure. The Spetzler-Martin system is commonly used, considering three factors: the size of the AVM (small, medium, large), its location (eloquent brain areas responsible for critical functions or not), and its venous drainage pattern (deep or superficial). This classification helps doctors assess the AVM’s risk of bleeding and guides treatment options. Overall, it provides a structured way to evaluate the complexity of the AVM and predict potential complications.
