After patients with hydrocephalus undergo shunt surgery, the incidence of shunt blockage is 30-40% in the first year after surgery, and increases by 5% each year thereafter. According to incomplete statistics, the incidence of post-shunt infection in some large hospitals can be as high as 30%, and most of the deaths of patients with hydrocephalus are caused by systemic multi-organ failure due to uncontrolled infection. In addition, a variety of complications can occur after shunt surgery such as excessive drainage, lacunar ventricular syndrome, cranial thickening, blindness, hearing loss, and persistent constipation. Some patients have repeatedly experienced postoperative shunt blockage and have undergone shunt surgery again and again, even 30 times. Even if the patient’s condition is stable or improves after shunt surgery, it is a complication called shunt dependency, which means that the patient’s condition is always dependent on the shunt to stay open, and if the shunt has excessive or too little drainage, there will be problems. It is an unattainable dream for shunt patients to be free from the curse of a lifetime tube and to resume a life of freedom. The advent of neuroendoscopic technology has gradually made the dream of freedom from shunt dependence a reality. By using neuroendoscopic surgery to treat post-shunt hydrocephalus, we can avoid the complications associated with the long-term use of ventriculoperitoneal shunts, free patients from the threat to their health caused by shunts, and enable them to “live freely.
