What is a hyperacute subdural hematoma?

A chronic subdural hematoma (SDH) is an old clot of blood on the surface of the brain beneath its outer covering. These liquefied clots most often occur in patients age 60 and older who have brain atrophy, a shrinking or wasting away of brain tissue due to age or disease.

What causes an acute subdural hematoma?

The most common cause for a subdural hematoma is head injury. This can be from a car crash, fall, or violent attack. This sudden impact can strain the blood vessels within the dura, causing them to rip and bleed. Sometimes small arteries also break within the subdural space.

What is the difference between subdural hematoma and subdural hemorrhage?

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.

How is subdural hematoma measured?

Volume of a subdural hematoma (gray area) can be approximated by halving the difference in volume between a large outer ellipsoid (solid line) and a small inner ellipsoid (dashed line).

Is a subdural haematoma a stroke?

If a subdural hemorrhage involves significant amounts of blood, it can cause a stroke, due to the pressure.

Is there a cure for a subdural hematoma?

For chronic subdural hematomas or when an acute hematoma is smaller than 1 cm in diameter, a surgeon may use burr hole surgery . During this procedure, the surgeon drills a small hole into the person’s skull and inserts a rubber tube to drain the blood. After surgery, a doctor will usually prescribe anti-seizure medication .

What to know about subdural hemorrhages?

A subdural hemorrhage describes a type of bleeding that causes irritation and pressure to the brain. A subdural hemorrhage is given that name because it is located in a region called the subdural space.

What to know about subdural hematoma?

ANSWER. A subdural hematoma is a collection of blood outside the brain. Subdural hematomas are usually caused by severe head injuries. The bleeding and increased pressure on the brain from a subdural hematoma can be life-threatening. Some subdural hematomas stop and resolve spontaneously; others require surgical drainage.

What causes subdural hematoma?

Causes of Subdural Hematoma. Subdural hematoma is usually caused by a head injury, such as from a fall, motor vehicle collision, or an assault. The sudden blow to the head tears blood vessels that run along the surface of the brain. This is referred to as an acute subdural hematoma.
