2 Information about the procedure

2.1

Middle meningeal artery embolisation (MMAE) involves restricting the blood supply to a non-acute subdural haematoma with an embolic agent injected into the middle meningeal artery. The procedure can be done for new or recurrent haematomas, and can be done on its own or with surgery to remove the haematoma.

2.2

The procedure is done by a trained interventional neuroradiologist, using general or local anaesthesia, under fluoroscopic guidance. A catheter is inserted into the common femoral or radial artery (or in certain rare cases, the temporal artery). A microcatheter is then guided into the middle meningeal artery. Angiography is used to select branches for embolisation. The target branches are then blocked using an embolic agent such as liquid agents, particle agents or coils. Once there is no flow in the target branches on angiography, the catheters are removed.
