Middle meningeal artery embolisation for chronic subdural haematomas
Closed for comments This consultation ended on at Request commenting lead permission
Description
A subdural haematoma is an abnormal collection of blood (haematoma) in the space between the membrane surrounding the brain and the brain itself (subdural space). It is usually caused by a head injury. The blood collection puts pressure on the brain, which interferes with its functioning.
Under a general or local anaesthetic, a tube (catheter) is inserted through an artery in the thigh or forearm. A microcatheter is then put through it into an artery that supplies the membrane (middle meningeal artery). Particles are then injected to block (embolise) the middle meningeal artery. The aim is to cut off the blood supply to the membrane around the haematoma, after which the haematoma should go away on its own.
