Patient's question:
Your friend's baby has just been born for one or two months, and then peripheral hydrocephalus appeared. The friends are terrified and don't know what to do. What should be done about peripheral hydrocephalus?Doctor's answer:
Extradural hydrocephalus refers to the accumulation of excessive fluid in the subarachnoid space within the cranial cavity, which is the space between the skull and the brain tissue. Under normal conditions, the subarachnoid space contains a small amount of fluid, and its quantity is maintained at a constant level due to a dynamic balance between secretion and excretion. However, in pathological conditions such as meningitis, inflammation and bleeding within the subarachnoid space, there may be an increase in cerebrospinal fluid secretion or impaired excretion, leading to fluid retention in the subarachnoid space. Additionally, in cases of frontal lobe atrophy or dysplasia, the increased space between the brain and the skull in the subarachnoid space, commonly referred to as congenital or inflammatory hydrocephalus, results in an increase in intraventricular fluid accumulation. As a consequence, the accumulation of fluid compresses the brain tissue, leading to brain atrophy, poor prognosis, and often requiring surgical treatment.
