Target population: patients 18 years of age or older who require surgical treatment with lumboperitoneal shunt surgery for traffic hydrocephalus Estimated sample size: 30 cases. Study design: this study is a multicenter prospective observational study, with lumbar puncture pressure measurement before and during surgery, and shunt valve setting pressure set according to the requirements of clinical practice in the hospital where it is performed, and the collection of relevant data, including preoperative lumbar puncture pressure, intraoperative lumbar puncture pressure after anesthesia, shunt valve initial pressure, shunt valve pressure at 6 months pressure, length of the intravertebral shunt, and length of the intraperitoneal shunt. Complications, shunt effects, and the number of shunt valve adjustments during the 6-month period were also observed and recorded.
