Guided Application of Ventricular Catheters (GAVCA)

This study has been completed.

Aesculap AG Identifier:
First received: March 13, 2013
Last updated: January 26, 2015
Last verified: January 2015
Failure of ventricular catheters remains a significant problem in patients with hydrocephalus. The purpose of this study is to determine whether the use of a simple instrument assisted by a smart phone application software can achieve a more precise placement of ventricular catheters than the standard free-hand placement technique.

Condition Intervention
Hydrocephalus Device: Thomale-Guide Other: Free-hand

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Randomized Controlled Multi-center Trial Comparing the Ventricular Catheter Location Between Instrument Guided and Freehand Placement.

Primary Outcome Measures:
  • Rate of he primary successful ventricular catheter placement with a Grade I or Grade I b and location in the ipsilateral ventricle [ Time Frame: Within the first 40 days ]

Enrollment: 144
Study Start Date: May 2013
Study Completion Date: January 2015
Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Thomale-Guide
Positioning of ventricular catheter with the Thomale-Guide instrument
Device: Thomale-Guide
Ventricular catheter placement with the Thomale-Guide instrument
Ventricular catheter placement without a guidance (free-hand)
Other: Free-hand
Ventricular catheter placement without a guidance (free-hand)

Detailed Description:

Free-hand placement of ventricular catheters (VC) is reported to be inaccurate in 10-40%. Furthermore, there is evidence that the quality of VC positioning is correlating with the risk for proximal shunt obstruction. Ultrasound or neuronavigation are used in order to improve to placement. However, they are associated with significant technical efforts and increased time.

In this study a simple instrument assisted by a smart phone application software is used in order to achieve precise placement of ventricular catheters. The results are compared with the standard free-hand procedure. Patients requiring a ventricular catheter are randomized to one of the two treatments. The primary outcome parameter is a qualitative and quantitative assessment of the position of the ventricular catheter on a post-operative image. The evaluation of the primary criteria is performed by a radiologist blinded to the randomization arm.
