Hydrocephalus is a disease that plagues many people today, as it can cause great harm to intelligence, limbs, vision and other aspects of a person’s life. Hydrocephalus is certainly a cause for concern, but with the rapid development of medical treatment today, once hydrocephalus is diagnosed, going to a regular hospital as soon as possible to take effective measures to intervene can not only effectively prevent further aggravation of the disease, but also get rid of the disease as soon as possible. When it comes to the treatment options for hydrocephalus, we have to talk about shunt surgery in detail here. It is reasonable to say that bypass, as a classical procedure with a long history in clinical practice, should be considered perfect in terms of preoperative preparation, intraoperative operation and postoperative complication management. However, this is not the case, and there are still many shortcomings in conventional shunts because of the small orifice size of the shunts, and shunt blockage may occur during the process of penetrating the brain tissue into the ventricles with a drainage tube or during the postoperative drainage process. What are the chances of hydrocephalus shunt blockage? The clinical incidence of hydrocephalus shunt blockage is about 20-40% or more. If a blockage occurs, it may be life-threatening if the local hospital is unable to handle it properly or if it is not handled properly. Many people may still hold on to the idea that they can’t have a blockage before surgery, but when the problem really occurs after surgery, they will regret it too late. Here to remind the majority of hydrocephalus patients, do not joke with their own health, to avoid the time to bring greater adverse consequences to themselves, to bring a heavier economic burden on the family. So what should be done if a patient is unfortunate enough to have a blocked tube after a shunt? In this case, patients should go to a specialized hospital to receive regular specialist treatment for cerebrospinal fluid in a timely manner.
