A Guide to Brain Injury and Subdural Hematoma

SUBDURAL НЕМАТОМAS A GUIDE TO BRAIN INJURY A subdural hematoma is a collection of blood on the surface of the brain. As a subdural hematoma expands in the subdural space, it raises the intracranial pressure as it deforms and displaces the brain. Subdural hematomas are usually the result of a serious head injury. The bleeding fills the brain area very rapidly, compressing brain tissue. This often results in brain injury and may lead to death. Subdural hematoma is the most View of brain from above with the top of the skull removed common type of traumatic intracranial mass lesion. A CT Scan or MRI is done to evaluate a head injury and to determine the presence of a hematoma.

FORCEFUL IMPACT Subdural hematomas are almost always caused by head trauma.

Emergency surgery may be needed to reduce pressure within the brain. This may involve drilling a small hole in the skull, which allows blood to drain and relieves pressure on the brain. 911 Large hematomas or solid blood clots may need to be removed through a procedure called a craniotomy, the surgical opening of the skull. Once the skull is removed a surgeon then opens the dura, removes the blood clot with suction Craniotomy Procedure Incision is made on the side of the head or irrigation, and identifies and controls sites of bleeding. The skull flap is then put back or reapproximated. Postoperative Result Hematoma was removed, relieving the Hematoma Skull flap is removed and dura opened, exposing the hematoma on the brain pressure on the brain Hematoma is 3 evacuated and the bleeding vessel are cauterized Skull flap After the bleeding vessel is repaired, the dura covering the brain is repaired and the skull flap is reapproximated Mount 02012 The Mount Sinai Medical Center, New York Sinai You are free to copy, distribute and transmit this content, but you must attribute the work to Mount Sinai Medical Center, New York Some information in the above graphic has been referenced from: http://www.ncbi.nim.nih govipubmedhealth PMHO001732

Subdural hematoma (SDH) is a collection of blood outside the brain, most often caused by traumatic head injury.
