Hydrocephalus is a general term for an increase in cranial pressure and ventricular enlargement secondary to an excess of cerebrospinal fluid and an increase in pressure due to a disorder in the production or circulation and absorption of cerebrospinal fluid, which enlarges the space occupied by normal cerebrospinal fluid. Hydrocephalus is a general term for an increase in cranial pressure and ventricular enlargement secondary to a disorder in the production or absorption of cerebrospinal fluid that results in excessive cerebrospinal fluid and increased pressure, which enlarges the space occupied by normal cerebrospinal fluid. There are many causes of hydrocephalus, such as congenital malformations, obstructive hydrocephalus caused by tumors, etc. However, the most common clinical condition is hydrocephalus caused by subarachnoid hemorrhage, cerebral hemorrhage, and impaired absorption of cerebrospinal fluid by arachnoid granules after craniocerebral trauma. The diagnosis is not difficult. Once hydrocephalus is diagnosed, surgery should be performed as soon as possible. For obstructive hydrocephalus caused by tumor, surgical removal of the tumor is the most important, while for patients with impaired absorption of cerebrospinal fluid, the main treatment is ventriculoperitoneal shunt surgery (see below for the surgical approach), which aims to drain excessive cerebrospinal fluid from the ventricles into the abdominal cavity for absorption by establishing a channel connection between the ventricles and the abdominal cavity. Our department is one of the first medical units in China to perform minimally invasive laparoscopic-assisted direct vision ventriculoperitoneal shunt surgery, with advanced technology and extensive experience. The surgical procedure takes about 1.5 hours, bleeding about 30ml, and the surgical incisions are two 3-cm incisions in the head and two 1-cm incisions in the abdomen, respectively. The shunt material adopts adjustable pressure tubes, and the pressure of the drainage tube opening can still be adjusted non-invasively after the operation, avoiding the risk of excessive drainage (which can lead to cerebral hemorrhage) or insufficient drainage (no relief of clinical symptoms), and at present we have more than 100 cases of shunt surgery every year, and through This technique has not resulted in a single case of excessive drainage (which can lead to cerebral hemorrhage) or insufficient drainage (no relief of clinical symptoms). The related cases have been noticed and reported by many domestic mainstream media such as Sohu.com, Netease.com and Yanzhao City News.
