How can subdural hematoma lead to death?
How can subdural hematoma lead to death?
A subdural hematoma is most often the result of a severe head injury. This type of subdural hematoma is among the deadliest of all head injuries. The bleeding fills the brain area very rapidly, compressing brain tissue. This often results in brain injury and may lead to death.
What is the mortality rate of a 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%.

What are the prognostic factors for subdural hematoma?
No clear prognostic factors are associated with chronic subdural hematoma. While some authors have found an association with preoperative level of neurological function and outcome, others have not. Early diagnosis before significant neurologic deterioration may correlate with a more favorable prognosis.
Can a subdural hematoma be a complication of craniotomy?
Acute subdural hematoma (SDH) as complication of craniotomy. Note significant mass effect with midline shift. Contraindications for surgery are determined on a case-by-case basis, depending on factors that relate to the patient’s neurologic and medical condition.
When does a subacute hematoma appear after a concussion?
Subacute: Symptoms usually appear hours to days or even weeks after the head injury. A subacute subdural hematoma can occur with a concussion. Chronic: This type of hematoma is more common in older people. Bleeding occurs slowly and symptoms may not appear for weeks or months.
Is it possible to remove a hematoma from the brain?
Although surgical intervention may be able to successfully remove the hematoma itself, patients with acute SDHs are often difficult to treat and may have a poor outcome due to underlying brain injury. The medical issues, especially in older patients with SDHs, may be complex.
Who is most likely to develop a subdural hematoma?
People with a bleeding disorder and people who take blood thinners are more likely to develop a subdural hematoma. A relatively minor head injury can cause a subdural hematoma in people with a bleeding tendency.
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 is the mortality rate for subdural hematoma (SDH)?
The mortality rate for patients with an acute SDH ranges from 50 percent to 90 percent. A significant percentage of these deaths result from the underlying brain injury and pressure on the brain that develops in the days after injury. Approximately 20 percent to 30 percent of patients will recover full or partial brain function.
What are the differential diagnoses for subdural hematoma?
The differential diagnosis of an acute traumatic subdural hematoma is the same as that for any traumatic, intracranial mass lesion. This includes intracerebral hematoma and contusion.

Acute subdural hematoma (ASD) is seen in 12% to 29% of severe TBI and and has a mortality rate of 40% to 60%. Some ASDs are caused by blood from hemorrhagic contusions and traumatic subarachnoid hemorrhage that extends to the subdural space due to tears of the arachnoid membrane.
When does a subdural hemorrhage cause severe brain injury?
This is more likely if there has been a fall or minor trauma to the head. An acute subdural hemorrhage develops over minutes to hours. If not diagnosed and treated promptly, it can cause severe brain injury and sometimes death. A chronic subdural hemorrhage develops over many days to weeks.
Why is the meninges called the subdural hematoma?
The purpose of the meninges is to cover and protect the brain. If you have a subdural hematoma, you have experienced a tear in a blood vessel, most commonly a vein, and blood is leaking out of the torn vessel into the space below the dura mater membrane layer. This space is called the subdural space because it is below the dura.
