What exactly is a subdural hematoma?

Blod clot. Blod clot or collection under the dura on the surface of the brain.
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.
Bleed next to brain. Subdural hematoma is bleeding between the inner and middle layers of the tissues wrapping the brain. It can be secondary to trauma or occur spontaneously, especially in patients with significant brain atrophy. Depending on size and rate of growth they can often be managed conservatively, but sometimes require neurosurgical drainage.

What exactly is chronic subdural hematoma?

Blood around brain. There are three layers of tissue that surround the brain, known collectively as the "meninges." the outermost layer is the dura mater, the middle layer the arachnoid mater, and the layer closest to the brain the pia mater. When veins that go between these layers rupture - often because of trauma - blood can start to pool between the dura mater and arachnoid mater causing a subdural hematoma.
Subdural hematoma. A chronic subdural hematoma typical occurs after a head injury but does not present with symptoms until days to weeks after the event. It is a collection of fluid that develops between a membrane over the brain called the dura and the brain itself. If symptomatic these often need to be drained.

What exactly is subdural hematoma?

Rupture of vessel. Blood clot on the surface of the brain caused by rupture of vein. Rupture of an artery on the surface would cause epidural bleed.
Intracranial blood. A subdural hematoma is a blood clot that forms between the brain and the fibrous membrane covering the brain (subdural space). It is usually a result of trauma with the stretching and tearing of a vein in the subdural space as the brain deforms during an acceleration, deceleration situation..
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.

What's a subdural hematoma?

Blood clot. A subdural hematoma is a blood clot that has formed on top of the brain and underneath the covering of the brain. It is usually due to a traumatic event or if the patient's blood is being thinned. It can be nonsurgical or surgical depending on how large it is and what the patient's neurological status is.

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.

What is a subdural hematoma?

Blood inside skull. Subdural hematomas are collections, usually venous blood, from a torn vein between the brain and the fibrous membrane surrounding the brain called the Dura Mater.

Can you tell me about subdural hematoma?

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.

What are the tests for subdural hematoma?

Ct/ MRI. In this day, usually a ct or MRI of the brain is done to rule out a subdural hematoma.
CT of the head. A ct scan of the head is the preferred study to rule out a subdural hematoma following a head trauma. In the subacute setting, a MRI of the brain can also be helpful.

What's the definition of subdural hematoma?

Brain bleed. A bleed that occurs in between the dura and arachnoid layers of the brain. This type of bleed occurs "outside" the brain, not within.
Brain hemorrhage. A subdural hematoma is often associated with traumatic brain injury. It usually occurs when a bridging vein between the dura and the brain is torn. It bleeds and fills the subdural space leading to pressure on the brain. These are effectively treated with surgery done by a neurosurgeon.

Coma in 50% Acute: 50% coma; others may have headache, vomiting, unsteady walking chronic or 15 days or more after onset: headaches, dizziness, memory loss, sleepiness, occasional seizures.
