Difference Between Epidural and Subdural

An epidural hematoma lies outside (on top) of the dura mater (epi is Greek for upon), while a subdural hematoma lies inside (beneath) the dura mater (sub is Greek for below) and outside the arachnoid mater.

Is subdural hematoma worse than epidural?

Because of associated brain injuries and complications of secondary injury, the outcome of subdural hematoma is worse than that of epidural hematoma in children. Surgical intervention may be necessary, especially with large subdural hematomas causing a mass effect.

How do you tell the difference between SDH and EDH?

Extradual hematoma (EDH) is the collection of blood between the inner skull table and dura, and appears as a biconvex-lens shape on imaging. In comparison to EDH, the subdural hematoma (SDH) is a collection of blood between the dura and arachnoid membrane and it has a biconcave-lens shape on imaging.

What is the difference between a subdural hematoma and an epidural hematoma quizlet?

Epidural hematoma treatment: surgically remove the mass and reduce the pressure it puts on the brain. Subdural cause: rupture of bridging vein that connect to the dural venous sinuses, resulting from acceleration-deceleration forces applied to the head from blunt trauma or whiplash.

What is the difference between a subdural and subarachnoid hemorrhage?

If the blood vessels are damaged, they bleed into the subdural space. Subarachnoid hemorrhage most commonly occurs after trauma where cortical surface vessels are injured and bleed into the subarachnoid space. Non-traumatic subarachnoid hemorrhage is most commonly due to the rupture of a cerebral aneurysm.

How long can you live with an epidural hematoma?

In adults, most recovery occurs in the first 6 months. Usually there is some improvement over 2 years. If there is brain damage, full recovery isn't likely.

How serious is an epidural hematoma?

An epidural hematoma is a potentially life-threatening complication of a head injury. If left untreated, a person can face serious consequences, including death. Even after prompt treatment, someone may have permanent brain damage or disability.

What is lucid period?

The lucid period is the time required for the clot to grow to proportions great enough to produce compression of the brain. The percentage of patients with epidural hematoma who have lucid intervals varies in different reports from 10%¹ to 72%.

Does epidural hematoma cross suture lines?

Epidural hematomas occur when an artery is injured and arterial blood accumulates between the dura and the calvarium. Do not cross suture lines because of the tight adherence of the dura to the calvarium and thus have a biconvex or elliptical appearance.

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 are the differences in signs and symptoms of an epidural and subdural hemorrhage?

Patients with an epidural hematoma can remain conscious with minimal symptoms, can become drowsy, or can progress to a coma immediately following their injury based on the size of the hematoma. A subdural hematoma occurs when the bleeding exists inside the dura, but still outside the brain.

What is a subdural hematoma quizlet?

Subdural Hematoma, a collection of blood trapped in the space beneath the dura mater, between the dura and arachnoid layers of the meninges.
