middle meningeal artery embolization
Middle meningeal artery (MMA) embolization is a minimally invasive endovascular procedure designed to treat chronic subdural hematomas by blocking blood flow to the MMA, preventing recurrent bleeding. Under local or general anesthesia, a catheter is inserted through a micro-puncture in the femoral or radial artery and navigated up to the external carotid system into the MMA under real-time fluoroscopic (X-ray) guidance. Angiography is performed to map the arterial anatomy and identify any dangerous anastomoses with the ophthalmic or internal carotid arteries. Once positioned safely, an embolic agent such as liquid embolic systems (e.g., Onyx, n-BCA), liquid-suspended microparticles (PVA), or microcoils is injected into the anterior and posterior branches of the MMA. This occludes the fragile, hypervascular membranes driving the hematoma, allowing the body to naturally reabsorb the collected blood and reducing the need for open surgical evacuation.
