What is the treatment for subdural hematoma?

Depends on size: It really depends on the size of the bleed, how long it has been there, and whether the bleeding is causing pressure effects. Small bleeds with no pressure effects are managed with rest and avoidance of a second impact. Larger bleeds may require decompression via a burr hole or craniotomy with evacuation of the bleed. Blood thinner medications may be discontinued to prevent ongoing bleeding.

Subdural hematoma: If small and not causing a shift of brain structures in the skull, observation may be all that is necessary. If there is indication that the subdural hematoma is growing or causing symptoms due to increased pressure in the head, surgical drainage is the treatment.

SDH: A subdural hematoma typically occurs from bridging cortical veins being torn causing blood to accumulate on the surface of the brain under the dural covering of the brain. Trauma is the most common cause. In the elderly, even relatively minor head trauma can cause a sdh. Surgery is often used to evacuate the hematoma.
