What is the subdural space?
The subdural space, also called the subdural cavity, is a fluid filled with an anatomical gap between the arachnoid and the dura mater. The space is created by trauma or pathological conditions and can penetrate the cerebrospinal fluid and blood and create physiological problems. Creating subdural space alone is not a problem, as layers can move back together after the end of the trauma. The side effects of trauma, such as subdural hematoma, are what can cause problems in the region. In addition, doctors can injections in this area due to an unexpected gap of error.
The brain and spine are protected by mening with layers called maternal. The PIA mater is closest to the brain and spine, the arachnoid mater is in the middle and the dura mater is the farthest layer. Subdural space is a potential gap that can open between the outer two layers.
Potential physiological space is possible, but only through some pathological change of some kind.The gold and the arachnoid layers are compressed firmly together. There are no nerves or tendrils of physically connecting layers. When the head or spine trauma occurs, these unconnected layers can move apart and create a subdural space.
The fluid can penetrate the gaping area. Cerebrospinal fluid is a sprung liquid that is commonly found between PIA and arachnoid maternal. The space between PIA layers and arachnoid layers are also potential. Trauma can cause division between them, allowing fluid to penetrate, or in the dead body, the dehydration of fluid may cause subdural space.
Studies suggest that the leakage of cerebrospinal fluid can also increase the chances of subdural hematoma. Blood can gather in subdural space due to injury, aneurysm or pathological bleeding. Blood can be clotted in space and causes a hematoma who is who pressure on the brain. AndThe hematomas will usually be absorbed back into the body, although serious cases may require surgery.
doctors must carefully carefully when injected into the subarachnoid layer. Injections are usually performed in this area for radiation or anesthetic purposes. If you do not notice that there is a present gap, it can lead to the release of the injection material into the space instead of the membrane layer. This can lead to insufficient concentration of injection material before the procedure.
