ShuntCheck can be used to detect CSF flow in asymptomatic hydrocephalus patients and can be used to detect no-flow in symptomatic patients with shunt obstruction.

Secondarily, the ShuntCheck test will yield the clearest results when patients are tested sitting up (or alternatively while supine)

Condition Intervention
CSF Flow Through the Shunt of a Hydrocephalus Patient
Device: ShuntCheck

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Physician Preference Study of the Utility of ShuntCheck to Detect Cerebrospinal Fluid (CSF) in Patients With Ventriculo-Peritoneal CSF Shunts

Secondary Outcome Measures:
  • ShuntCheck result of "Flow Not Confirmed" for symptomatic shunted patients with shunt obstruction [ Time Frame: Single visit ]

Estimated Enrollment: 200
Study Start Date: September 2007
Estimated Study Completion Date: September 2015
Estimated Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Diagnostic Device: ShuntCheck
Thermal dilution test for CSF flow
