Treatment of a subdural hematoma depends on its size and rate of growth. Some small subdural hematomas can be managed by careful monitoring as the blood clot is eventually resorbed naturally. Others can be treated by inserting a small catheter through a hole drilled through the skull and sucking out the hematoma. [citation needed]
Subdural hemorrhage (SDH) results from tearing of the bridging veins in the subdural space between the dura and arachnoid mater. It can cross the suture lines, but not across dural reflections such as falx cerebri or tentorium cerebelli. [4] Therefore, subdural hematoma always limited to one side of the brain. [3]
A subdural hematoma occurs when there is an abnormal collection of blood between the dura and the arachnoid, usually as a result of torn bridging veins secondary to head trauma. An epidural hematoma is a collection of blood between the dura and the inner surface of the skull, and is usually due to arterial bleeding.
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
Epidural hematoma involves bleeding into the area between the skull and the dura mater, the outermost of the three membranes surrounding the brain. [11] In subdural hematoma, bleeding occurs between the dura and the arachnoid mater. [23] Subarachnoid hemorrhage involves bleeding into the space between the arachnoid membrane and the pia mater. [23]
The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or major disability than ischemic stroke or subarachnoid hemorrhage, and therefore constitutes an immediate medical emergency.
George Gershwin died after emergency surgery of a large brain tumour, believed to have been a glioblastoma.The fact that he had suddenly collapsed and become comatose when he stood up on his last day of life, has been interpreted as brain herniation and Duret haemorrhages.
Controlling of hemorrhage as discussed above is the most important step in this phase. Eviscerating the intra-abdominal small bowel and packing all four abdominal quadrants usually helps surgeons establish initial hemorrhagic control. Depending up on the source of hemorrhage a number of different maneuvers might need to be performed allowing ...
