    What the procedure involves

    This procedure is done using general or local anaesthesia, under fluoroscopic guidance. A catheter is inserted into the common femoral or radial artery, and a microcatheter is then guided into the MMA. Angiography is used to select MMA branches for embolisation and to detect collateral vessels.

    If there are no significant collateral vessels, target branches are embolised. If there are significant collateral vessels, they are either occluded using coils before embolisation, or the microcatheter is advanced more distally to avoid them. Once there is no flow in the MMA target branches on angiography, the catheters are removed.

    This procedure aims to eliminate the blood supply from the MMA to the membrane around the haematoma and to allow the eventual spontaneous resolution of the haematoma.
