Patient's question:
The child has undergone brain surgery more than three years ago, but the effect is not very good; fainting occurs frequently, usually once a month. During fainting, the lips and skin turn purple for 2-3 seconds and then recover. The child is often drowsy.Doctor's answer:
Hydrocephalus is caused by excessive cerebrospinal fluid secretion or (and) circulation due to intracranial diseases, and the accumulation of cerebrospinal fluid in the intracranial cavity is caused by ventricular dysfunction. There are many causes of persistent hydrocephalus, and the three common reasons are as follows: congenital malformations, such as aqueductal stenosis of the midbrain, ependymal formation or occlusion, and infection: intrauterine infections such as various viruses, protozoa, and syphilis spirochetes meningitis that are not controlled in a timely manner.
