Final answer:
Possible complications associated with an intracranial haemorrhage and a rise in volume in this fixed space include loss of function, compromised blood flow, and implications for the movement of cerebrospinal fluid.
Step-by-step explanation:
A rise in volume in a fixed space, such as the cranial vault, can lead to complications associated with an intracranial haemorrhage. The accumulated blood fills the space, causing physical pressure on the brain, which can result in the loss of function. As the blood pools in the nervous tissue, the blood-brain barrier can break down, allowing additional fluid to accumulate in the region, leading to edema.
In addition to the physical pressure, the rise in volume can also cause compromised blood flow beyond the site of hemorrhage. The local arteries may become squeezed, restricting the blood flow to other areas of the brain.
Furthermore, a rise in volume can lead to constricted blood flow in the cerebrospinal fluid, which can affect the movement of CSF and intracranial blood flow. This can have implications for the neuronal and glial vulnerabilities and may result in further complications.
