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

RenJi Hospital30 enrolled

Overview

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.

Conditions

Hydrocephalus, Communicating

Interventions

surgery (any volume) and / or pharmaceuticals treatment initiated or planned or only dynamic observation, in accordance with current clinical guidelines

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.

Inclusion Criteria: 1. Age of 18 years or older; 2. Confirmed diagnosis of communicating hydrocephalus; 3. Signed informed consent for surgery and informed consent for research. Exclusion Criteria: 1. Pregnant women; 2. Inappropriate for lumboperitoneal shunt surgery despite the diagnosis of communicating hydrocephalus.

Outcomes

Primary Outcomes

primary outcome

1. Measurement of preoperative bedside lumbar puncture pressure(cmH2O); 2. Measurement of lumbar puncture pressure after anesthesia during lumboperitoneal shunt surgery(cmH2O) ; 3. Initial setting of shunt valve; 4. Setting of shunt valve at 6 months after lumboperitoneal shunt surgery

Time frame: preoperation to 6 months after surgery

Secondary Outcomes

secondary outcome

The numbers of complications related to the lumboperitoneal shunt at 6 months after the shunt operation, including: subdural hemorrhage, ventricular hemorrhage, intracerebral hemorrhage, subdural effusion, shunt obstruction, resetting the shunt, intracranial infection, and epilepsy.
