Embolization of the Middle Meningeal Artery for Refractory Chronic Subdural Haematoma. Usefulness for Patients under Anticoagulant Therapy.
Endovascular embolization of the middle meningeal artery was performed in two cases of refractory chronic subdural haematoma (CSDH) after repeated burr hole and irrigation surgeries. The embolization prevented expansion of the CSDH in both cases, and the haematoma disappeared completely in one case. The expansion of CSDH is considered to result from repeated bleeding from the macrocapillaries on the haematoma capsule. Embolization of the middle meningeal artery appears to be useful to eliminate the blood supply to this structure.
