Intracranial hypertension (IH), also called increased ICP (IICP) or raised intracranial pressure (RICP), refers to elevated pressure in the cranium. 20–25 mmHg is the upper limit of normal at which treatment is necessary, though it is common to use 15 mmHg as the threshold for beginning treatment.
EBP is also used to treat spontaneous intracranial hypotension (SIH). [5] [9] EBP has been used to treat pseudomeningoceles and leaks around intrathecal pumps. [14] For SIH, the same administration technique is used but at a different location with a different amount of blood injected. [15]
Spontaneous CSF rhinorrhoea is the most common acquired defect in the skull base bones (anterior cranial fossa) causing spontaneous nasal liquorrhea. Defects are often localized in the sphenoid bone and the ethmoid bone. [1] Congenital CSF rhinorrhoea is the least common type of CSF rhinorrhoea. [1]
Dural ectasia is defined as a ballooning or outpouching of the dura with a dural volume greater than two standard deviations above the mean value in controls. [9] It is usually identified by MRI or CT Scan, [7] which can be used to distinguish it from tumors. [16]
