What is a chronic subdural hematoma?


What is a chronic subdural hematoma? General Information. 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.

Can you recover from chronic subdural hematoma? Chronic subdural hematomas that cause symptoms usually do not heal on their own over time. They often require surgery, especially when there are neurologic problems, seizures, or chronic headaches.

How is chronic subdural hematoma treated? Treatment options for chronic subdural hematoma

Drugs known as corticosteroids relieve inflammation and are sometimes used to ease swelling in the brain. Chronic SDH can be treated surgically. The procedure involves making tiny holes in the skull so blood can flow out. This gets rid of pressure on the brain.

What is the difference between acute and chronic subdural hematoma? Generally, acute subdural hematomas are less than 72 hours old and are hyperdense compared with the brain on computed tomography scans. The subacute phase begins 3-7 days after acute injury. Chronic subdural hematomas develop over the course of weeks and are hypodense compared with the brain.

What is a chronic subdural hematoma? – Related Questions

Can chronic subdural hematoma cause death?

Yes, a subdural hematoma can be a serious event. Occasionally, the bleed is slow and the body is able to absorb the pooled blood. However, if the hematoma is severe, the buildup of blood can cause pressure on the brain. This pressure can lead to breathing problems, paralysis and death if not treated.

What happens if subdural haematoma is left untreated?

If left untreated, a subdural haematoma can grow and press on the brain. Pressure on the brain can be harmful. This pressure forces the brain against the skull, causing damage to the brain, as well as hindering the brain’s ability to function properly.

What are the long term effects of a subdural hematoma?

Many people are left with some long-lasting problems after treatment for a subdural haematoma. These can include changes to your mood, concentration or memory problems, fits (seizures), speech problems, and weakness in your limbs. There’s also a risk the haematoma could come back after treatment.

Is chronic subdural hematoma an emergency?

A subdural hematoma may happen after a severe head injury. Doctors often treat subdural hematomas with surgery to ease pressure on the brain. If you have a subdural hematoma, you need emergency treatment. Symptoms may happen right away or develop over weeks.

How long can you live with a subdural hematoma?

Favorable outcome rates after acute subdural hematoma range from 14-40%. Several series have shown an increase in favorable outcome in younger patients. Age younger than 40 years was associated with a mortality rate of 20%, whereas age 40-80 years was associated with a mortality rate of 65%.

Can a subdural hematoma be treated without surgery?

Chronic subdural hematoma can be treated with tranexamic acid without concomitant surgery. Tranexamic acid might simultaneously inhibit the fibrinolytic and inflammatory (kinin-kallikrein) systems, which might consequently resolve CSDH.

How serious is subdural hematoma?

A subdural haematoma is a serious condition that carries a high risk of death, particularly in older people and those whose brain was severely damaged. Acute subdural haematomas are the most serious type because they’re often associated with significant damage to the brain.

Is a subdural haematoma a stroke?

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

Can subdural hematoma heal itself?

This type of subdural hematoma typically goes away on its own over the span of a few weeks.

Can a subdural hematoma cause dementia?

Chronic subdural hematoma (cSDH) is a common intracranial pathology, and a leading cause of reversible dementia.

What happens if you hit your head while on blood thinners?

“For people on blood thinners, any head injury — even a fall from ground level — can be dangerous. A non-event head injury in someone taking a blood thinner can cause a brain bleed causing blood to collect on the outside or inside of the brain in a hematoma.”

What does a hematoma look like?

Hematomas can be seen under the skin or nails as purplish bruises of different sizes. Skin bruises can also be called contusions. Hematomas can also happen deep inside the body where they may not be visible. Hematomas may sometimes form a mass or lump that can be felt.

How do you know if your brain is bleeding after hitting your head?

Confusion. Unequal pupil size. Slurred speech. Loss of movement (paralysis) on the opposite side of the body from the head injury.

What does a subdural hematoma look like on CT?

On noncontrast CT scan, an acute subdural hematoma appears as a hyperdense (white), crescent-shaped mass between the inner table of the skull and the surface of the cerebral hemisphere (see the images below).

What is the surgery for a subdural hematoma?

Craniotomy. A craniotomy is the main treatment for subdural haematomas that develop soon after a severe head injury (acute subdural haematomas). During the procedure, the surgeon creates a temporary flap in the skull. The haematoma is gently removed using suction and irrigation, where it’s washed away with fluid.

Can you drive after a subdural Haematoma?

A period off driving will normally be recommended and you may be required to notify DVLA about your medical condition. Following minor head injury, patients are advised not to drive for at least 24 hours post-injury; refraining from driving until completely recovered is recommended.

What is the mortality rate of subdural hematoma?

Since 1981, it has been strongly held that the critical factor in overall outcome from acute subdural hematoma is timing of operative intervention for clot removal; those operated on within 4 hours of injury may have mortality rates as low as 30% with functional survival rates as high as 65%.

Can you have a subdural hematoma without trauma?

Some subdural hematomas occur without cause (spontaneously). The following increase the risk for a subdural hematoma: Medicines that thin the blood (such as warfarin or aspirin)

How long does it take a subdural hematoma to reabsorb?

A hematoma is not a bruise. Depending on the cause, it can take anywhere from 1 to 4 weeks for a hematoma to go away.

Can a hematoma last for years?

Occasionally a haematoma remains serous and persists indefinitely as an intramuscular ‘cyst’.

How does a brain bleed cause death?

A lack of oxygen in the brain can lead to swelling, or cerebral edema. Pooled blood from a bleed can also collect into a mass known as a hematoma. The extra pressure of this can prevent oxygen from reaching brain cells, which can result in their death.
