What is extradural hemorrhage?

Extradural hematoma (EDH), also known as an epidural hematoma, is a collection of blood that forms between the inner surface of the skull and outer layer of the dura, which is called the endosteal layer. They are usually associated with a history of head trauma and frequently associated skull fracture.

What causes Extradural haemorrhage?

How is an extradural hematoma treated?

In most cases, your doctor will recommend surgery to remove an epidural hematoma. It usually involves a craniotomy. In this procedure, your surgeon will open up part of your skull so they can remove the hematoma and reduce the pressure on your brain. In other cases, your doctor may recommend aspiration.

What is the prognosis for an extradural hemorrhage?

Treatment and prognosis. Prognosis, even with a relatively large hematoma, is in general quite good, as long as the clot is evacuated promptly. A smaller hematoma without mass effect or swirl sign can be treated conservatively 2, sometimes resulting in calcification of the dura.
