The water in hydrocephalus is not the water we normally use, but the cerebrospinal fluid that circulates between the brain and spinal cord, a colorless, clear liquid. The cerebrospinal fluid is important for the protection of the brain and spinal cord, but if the circulation of cerebrospinal fluid is abnormal due to craniosynostosis or other factors, the amount of cerebrospinal fluid increases and hydrocephalus forms. If hydrocephalus is formed, it means that the brain is in a pathological state, and if it is not treated and controlled in time, the development of hydrocephalus can be serious and cause more damage. Therefore, once hydrocephalus appears, we must actively take treatment measures. At present, the treatment of hydrocephalus is mainly surgery, and the conventional surgical method is hydrocephalus shunt surgery. Is hydrocephalus surgery a major operation? Many patients are worried about the risk of surgery is too big, so they hesitate to go to the hospital surgery, as a result, their condition aggravates their own more pain, not to say, to the later treatment also increased the difficulty. In fact, hydrocephalus shunt surgery is not a major surgery and the procedure is not complicated. However, conventional hydrocephalus shunts have a high incidence of postoperative complications, such as infection and blockage of the tube.
