Explain the Difference Between Epidural and Subdural Hematomas

Below the dura is the arachnoid separated by the subdural space. Diffuse crescent shaped collection of blood in the subdural space.

Anatomy Epidural Vs Subdural Hematoma Image

Thats going to kill you much more quickly.

. Localized lenticular biconvex disk lens-shaped collection of blood in the epidural space. In a subdural hematoma the veins of your brain run in the space between the. The delicate inner layer is the pia mater the middle layer is the arachnoid filled with fluid to cushion the brain and the final outer layer is called the dura mater.

These three layers are called the meninges. Epidural bleeding occurs between the skull and dura. Bleeding into the space between the dura the brain cover and the brain itself.

Unlike epidural hematomas which cannot expand past the sutures of the skull subdural hematomas can expand along the inside of the skull creating a concave shape that follows the curve of the brain stopping only at dural reflections like the tentorium cerebelli and falx cerebri. Skull fracture from blunt trauma causes laceration of arterial vessels most commonly the middle meningeal artery. So you will die from that kind of an epidural hematoma really very quickly but its a very rare form and not recognized very often.

Whereas subdural bleeding occurs between the dura and arachnoid. Because this is an arterial hemorrhage the hematoma develops rapidly. INTRACRANIAL subdural hematoma is an infrequent but well-documented neurologic complication of epidural catheter placement that is typically associated with obvious dural puncture at the time of insertion15This complication is also associated with spinal anesthesia in which dural puncture is intrinsic to the procedure as well as other instances of frank.

If you have a subdural hematoma blood is leaking out of a torn vessel into a space below the dura mater a membrane between the brain and the skull. 1An early theory about the formation of CSDH was of a traumatic injury causing tearing of the bridging veins traversing from the brain to the draining. This space is called the subdural space.

Venous epidural hematomas are common in pediatric patients. Epidural hematomas edh or subdural hematomas sdh can definitely occur after a fall. Anytime one strikes their head on the ground a fracture can occur that can lead to tearing of an epidural artery that can lead to edh.

- Symptoms strong and felt very rapidly. Unconsciousness followed by a lucid interval. Epidural hematomas edh or subdural hematomas sdh can definitely occur after a fall.

Epidural hematomas are usually caused by bleeding from an artery that nourishes the meninges known as the middle meningeal artery while subdural hematomas are usually due to bleeding from veins that drain blood away from the surface of the brain. Subdural Hematoma Subdural hemorrhage occurs when blood enters the subdural space which is anatomically the arachnoid space. Symptoms include ongoing headache confusion and drowsiness nausea and vomiting slurred speech and changes in vision.

- Usually a damaged artery. Yet another difference between epidural. Hemorrhage occurs into the epidural space which lies between the dura and inner surface of the skull Fig.

Subdural hematomas can be serious. - Blood pools between skull bone and dura mater. In the skull this space doesnt exist because the dura is attached to the bone.

The outermost and thickest the dura mater is separated from the bone by the epidural space. 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. Epidural and subdural hematomas are produced by ruptures of different blood vessels.

A pool of blood trapped within the skull and the dura. Click card to see definition. A subdural hematoma occurs when the bleeding exists inside the dura but still outside the brain.

The features of a subdural vs an epidural hematoma differ based on CT findings symptoms location within the. Or the movement of the brain with a fall can tear a bridging subdural vein-thus a sdh. If the hematoma puts increased pressure on the brain neurological abnormalities including slurred speech impaired gait and dizziness may result and progress to coma and.

A venous epidural hematoma occurs when there is a skull fracture and the venous bleeding from the skull fracture fills the epidural space. Minutes to hours later signs of intracranial compression begin. Subdural hematomas can either be acute occurring and.

Chronic subdural haematoma CSDH is an encapsulated collection of fluid blood and blood degradation products layered between the arachnoid and dura mater coverings on the brains surface Fig. However it does exist in the spinal cord where the veins and fat are. The middle meningeal artery lying under the temporal bone is often torn.

Arterial bleeding secondary to a tear of the middle menigeal artery or its branches. This space is called the subdural space. They are the result of an intracranial hemorrhage that can then form into a subdural or epidural hematoma depending on the location.

Subdural and epidural hematomas are abnormal collections of blood within the meninges surrounding the brain. Death within hours if hematoma is not drained talk and die syndrome Subdural CT findings. Or the movement of the brain with a fall can tear a bridging subdural vein-thus a sdh.
