Subdural Hematoma A subdural hematoma occurs when a blood vessel near the surface of the brain bursts. Blood builds up between the brain and the brain's tough outer lining. The condition is also called a subdural hemorrhage. In a subdural hematoma, blood collects immediately beneath the dura mater. The dura mater is the outermost layer of the meninges. The meninges is the three-layer protective covering of the brain. A subdural hematoma is a life-threatening problem because it can compress the brain.

What are the types of hematomas? Subdural hematomas also occur because of trauma but the injury is usually to the veins in the brain. This causes a slower leak of blood, which enters the 'subdural' space below the dura. Bleeding into the subdural space may be very slow, gradually stop, and not cause acute symptoms.ubdural hematomas also occur because of trauma but the injury is usually to the veins in the brain.

What Happens When a Brain Bleeds? Now, to answer your question, a subdural hematoma is basically bleeding into the space between the brain cover (dura mater) and the brain itself. More specifically, there are blood vessels running through the brain and in the spaces between the outside of the brain and the inside of the skull. During a brain injury, any of these vessels can tear and bleed. Ruptured vessels running in the subdural space — typically veins — cause subdural hematomas. Ruptured vessels running through the epidural space — typically arteries — cause epidural hematomas.

Traumatic Subarachnoid Hemorrhage Bleeding into this fluid-filled space can be caused by injury or rupture of the blood vessels that supply blood to the brain. Traumatic subarachnoid hemorrhage is the most common cause of SAH overall. A large percentage of traumatic brain injuries involve some component of this type of bleeding. However, SAH can occur from other causes as well.

Hematoma What are the causes of hematoma? The most common cause of a hematoma is injury or trauma to blood vessels. This can happen as a result of any damage to blood vessels that can disrupt the integrity of the blood vessel wall. Even minimal damage to a small blood vessel can result in a hematoma.

Subdural Hematoma A subdural hematoma occurs when blood collects on your brain’s surface beneath the skull. Subdural hematomas can be life-threatening. They usually result from a head injury. Subdural hematomas are either acute or chronic. Acute subdural hematomas commonly form because of a severe head injury. Chronic subdural hematomas develop due to a minor head injury. A blood clot on the surface of the brain is also called a subdural hematoma.

History Chronic subdural hematoma. One quarter to one half of patients with chronic subdural hematoma have no identifiable history of head trauma. If a patient does have a history of head trauma, it is usually mild. Of patients who have sustained head injury, symptoms develop after 1-4 weeks in 25%.

subdural hematoma This enlargement can compress the brain itself, possibly leading to death if the blood is not drained. The time between the injury and the appearance of symptoms can vary from less than 48 hours to several weeks, or more. Symptoms appearing in less than 48 hours are due to an acute subdural hematoma.

Intracranial Hematomas Pockets of Blood in the Brain. A head injury can cause bleeding in the brain. It can result in a pocket of blood between the skull and the outer layer of tissue covering the brain. This pocket of blood is called an epidural hematoma. Or a pocket of blood may form between the outer and middle layers of tissue. This pocket of blood is called a subdural hematoma.

Chronic Subdural Hematoma Subdural hemorrhage - chronic; Subdural hematoma - chronic; Subdural hygroma. A subdural hematoma develops when the tiny veins that run between the dura and surface of the brain (bridging veins) tear and leak blood. This is usually the result of a mild head injury.

- Subdural hematomas are almost always caused by head trauma, although in rare cases, they can occur spontaneously. Serious head injuries can cause acute subdural hematomas, in which the torn veins bleed rapidly into the subdural space, and pressure on the brain builds quickly.

Introduction A subdural haematoma occurs when a blood vessel in the space between the skull and the brain (the subdural space) is damaged. Blood escapes from the blood vessel, leading to the formation of a blood clot (haematoma) that places pressure on the brain and damages it.
