The formation of hydrocephalus is greatly related to excessive cerebrospinal fluid, a colorless and transparent liquid in the human skull and brain. Hydrocephalus is one of the most prevalent conditions that can lead to a series of neurological dysfunctions, and it is important to treat it in a timely manner. Hydrocephalus shunt is a feasible means of treating hydrocephalus, however, many patients may not know much about this procedure. Here we first explain how hydrocephalus bypass surgery is performed. Ventriculoperitoneal shunt is a major procedure that is widely used in clinical practice. It mainly involves using a tube to shunt excess cerebrospinal fluid from the skull to the abdominal area to absorb it, and the procedure is relatively simple. Ventriculothoracic and ventriculoatrial shunts operate on the same principle, but with different shunting sites. It is important to remind that the above-mentioned conventional shunts are prone to various postoperative complications, and blockage is a major problem that often plagues patients, and may be life-threatening if not properly handled by local hospitals or if not handled properly. There is also a very high chance of infection, which can easily cause more harm to the patient. Therefore, it is necessary to be cautious in treating hydrocephalus and not to take any chances to avoid bringing more trouble to yourself and causing more financial burden to your family. This technique, which starts with long-range cerebrospinal fluid drainage and cerebrospinal fluid purification until the cerebrospinal fluid reaches the standard and then a modified ventriculoperitoneal shunt is performed, achieves ideal results in the treatment of various types of hydrocephalus, and has a small chance of postoperative complications and high safety.
