BACKGROUND: The diagnosis of shunt malfunction is largely made by subjective clinical history and assessment in association with neurodiagnostic imaging. OBJECTIVE: To evaluate the use of a transcutaneous thermal convection device for the diagnosis of shunt malfunction. METHODS: We present the results of a trial of a commercially available device under an IRB approved protocol. All patients had neurodiagnostic studies that defined their shunt function at the time of transcutaneous thermal convection measurement. 37 shunts were studied in 35 patients. Criteria for inclusion were that patients were between the ages of 0 -18 years, were due within a 3-month period for routine follow-up evaluations, and had neurodiagnostic imaging (CT or MRI) as part of this visit and a shunt series. All patients were seen in routine follow-up and none had clinical symptoms of shunt malfunction. RESULTS: Three patients had fractured shunts. The remaining 32 patients all had functioning shunts as determined by clinical criteria, CT or MRI scans and, when appropriate, a shunt series. In these remaining patients, flow was initially confirmed in only 40%. After some filtering of the data, this was increased to 51%. While these results were disappointing, they outline the current issues with the technique, state of its utility and point to the need of further refinement. CONCLUSION: Our current research suggests CSF flow as detected by thermoconvection analysis is not a reliable indicator of shunt function in the pediatric population. |
