ETV Versus Shunt Surgery in Normal Pressure Hydrocephalus

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00946127
Recruitment Status : Terminated (Unable to recruit patients and lack of efficacy in ETV arm)
First Posted : July 24, 2009
Last Update Posted : October 3, 2012

Daniele Rigamonti, Johns Hopkins University

Brief Summary:
The purpose of this study is to test and compare the efficacy of Endoscopic Third Ventriculostomy with shunting of Cerebrospinal fluid (CSF)for treatment for patients of Normal pressure Hydrocephalus.

Condition or disease Intervention/treatment
Hydrocephalus Procedure: Ventriculoperitoneal Shunt Placement Procedure: Endoscopic Third Ventriculostomy(ETV)

Detailed Description:
Normal pressure Hydrocephalus is a reversible disorder of cognition and gait disorder.Currently the shunting of CSF is the recommended treatment of these patients. Even though shunts are known to be beneficial treatment of Hydrocephalus they often need treatment or revision for infection or malfunction. Endoscopic Third Ventriculostomy is a treatment without complications of shunt and is known to benefit obstructive forms of hydrocephalus.Few studies have also shown that it may be efficacious treatment Normal pressure Hydrocephalus.

Group/Cohort Intervention/treatment
Shunt Arm
Ventriculoperitoneal Shunt
Procedure: Ventriculoperitoneal Shunt Placement
In the subjects who choose this arm, at the start of study- CSF (Cerebrospinal fluid ) will be shunted to peritoneum by placing a ventriculoperitoneal shunt catheter with or without shunt valves or anti-siphon device.

ETV arm
Endoscopic Third Ventriculostomy
Procedure: Endoscopic Third Ventriculostomy(ETV)
Patients who choose to undergo ETV arm would undergo a ventriculostomy at the start of study.

Primary Outcome Measures :
  1. Efficacy: Cognitive outcomes using RAVLT scale. Gait Outcomes evaluated based on Tinneti Gait and Balance Test. Functional Independence evaluated using Barthel index. [ Time Frame: 1, 3, 6, 12 months after surgery ]
  2. Safety [ Time Frame: 0 through 12 months from Surgery ]
    Incidence of operative complications related to insertion of a shunt or performing ETV Intra-operative hemorrhage Post Operative amnesia Post Operative hemorrhage Infections Others Incidence of complications related to either of the two procedure over long term follow-up Infection Shunt malfunction ETV closure Others

Secondary Outcome Measures :
  1. Efficacy: Cognitive changes using Trails A& B. Gait changes based upon Timed Up and Go task and Gait Rite analysis. [ Time Frame: 1 months, 3 months, 6 months and 1 year ]
