Functional Outcomes After LumbOpenitoneal Shunt Placement UndeR Local Anesthesia for Patients With Idiopathic Normal preSsure Hydrocephalus (FLOURISH) Trial

Sponsor: Institute for Clinical Effectiveness, Japan

View on ClinicalTrials.gov

Summary

This study is a prospective observational registry study that enrolls all patients aged 60 years or older suspected of having idiopathic normal pressure hydrocephalus based on the Third Edition of the Guidelines for the Diagnosis and Treatment of Idiopathic Normal Pressure Hydrocephalus. From the cohort registered, patients judged to be candidates for surgery based on the 3rd Edition of the Guidelines for the Diagnosis and Treatment of Idiopathic Normal Pressure Hydrocephalus. These patients will be randomized 1:1 to undergo either ventriculoperitoneal shunt surgery under general anesthesia or lumbar peritoneal shunt surgery under local anesthesia. A randomized clinical trial would attest the non-inferiority of lumbar peritoneal shunt surgery under local anesthesia compared to ventriculoperitoneal shunt surgery under general anesthesia regarding the improvement in timed up-and-go test scores at 3 months post-surgery relative to pre-surgery levels.

PROCEDURE

ventriculoperitoneal shunt surgery under general anesthesia

ventriculoperitoneal shunt procedure was performed via right posterior horn puncture under general anesthesia
