Guidance assessment consultation for HTG10869 Middle meningeal artery embolisation for non-acute subdural haematomas

The brain is surrounded by a membrane called the dura. A subdural haematoma is a collection of blood in the space between the dura and the brain, usually caused by a head injury. This puts pressure on the brain and affects how it works. When the blood has been present for some time, often weeks or months, and there have been some changes in normal biological processes, it is called a non-acute subdural hematoma.

The aim of the procedure is to stop the bleeding and reduce pressure on the brain. Parts of the artery that supplies the dura with blood (the middle meningeal artery) are blocked (embolisation) under general or local anaesthesia. To reach the brain, a small tube (catheter) is inserted into an artery, usually in the thigh or forearm. A second, smaller catheter is then put through it to reach the middle meningeal artery. A blocking agent is then injected to block the artery.

NICE interventional procedures guidance applies to the NHS in England, Wales and Northern Ireland.
