A Prospective Observational Study of Perioperative Lumbar Puncture Pressure and Shunt Valve Pressure Management in Patients with Communicating Hydrocephalus Undergoing Lumboperitoneal Shunt Surgery

Lumboperitoneal shunt (LPS) involves connecting the subarachnoid space of the lumbar spine to the peritoneal cavity through a pressure-adjustable unidirectional valve to shunt the appropriate amount of cerebrospinal fluid from the ventricles to the peritoneal cavity via the spinal canal, where it is absorbed through the peritoneum, to alleviate the increased intracranial pressure caused by the communicating hydrocephalus and the corresponding clinical symptoms.
