Chronic Subdural Hematoma (cSDH) is a condition where there is a slow buildup of blood on the surface of the brain, under its outer covering (the dura). Sometimes, usually after a small bump or fall, tiny vessels that connect the brain to its outer covering can leak a small amount of blood.
Common symptoms can include a headache that slowly gets worse, confusion or memory problems, weakness on one side of the body, trouble walking or balance problems, sleepiness or changes in personality. It’s more common in older adults, especially those taking blood thinners.
Treatment depends on how big it is and how severe the symptoms are. Small ones might be watched and can sometimes go away on their own. Larger ones may need embolization to decrease the likelihood of recurrent hemorrhage, hemorrhage growth or future surgery to drain the blood.
Middle Meningeal Artery (MMA) Embolization for Chronic Subdural Hematoma
MMA embolization is a minimally invasive, image-guided procedure used to treat chronic subdural hematomas (cSDH). By selectively blocking small branches of the middle meningeal artery that supply the membranes fueling hematoma recurrence, the procedure promotes hematoma resolution and reduces the risk of reaccumulation. Performed through a small catheter inserted via the wrist or groin, MMA embolization offers a safer, less invasive alternative or adjunct to surgical evacuation, particularly for patients at high surgical risk or with recurrent cSDH.
