Obstructive hydrocephalus: depending on the situation, neuroendoscopic triple ventriculostomy is preferred, with minimal trauma and quick recovery, without subcutaneous placement of a tube and with the incision hidden in the hair. Traffic hydrocephalus: ventriculo-abdominal shunt is the most classic procedure, in which small openings are made in the head and abdomen to connect the ventricles and the abdominal cavity respectively, and a subcutaneous tunnel is formed in the middle to open a bypass to introduce the excess “fluid” into the abdominal cavity for absorption. The ventriculo-atrial shunt is used when the abdomen is not available (multiple abdominal surgeries, when the possibility of blockage and infection is very high), and a small opening is made in the neck to introduce the excess fluid into the large jugular vein near the right atrium. Not all hydrocephalus needs to be treated. If the fluid is stable and there are no symptoms associated with it, it can be followed up and observed without active intervention; if the symptoms caused by hydrocephalus are obvious, early intervention is also indicated. The technology of hydrocephalus treatment is mature, the complications are small and the results are obvious. If the infant’s head circumference increases significantly and the bulge of fontanel is obvious, hydrocephalus is the first consideration and needs to be examined as early as possible; once the cerebral cortex is pressurized for a longer time and thinned, it will affect the brain development.
