Brief Review of Reliability of the Radiopharmaceutical Shunt Study Reliability in CSF Shunt Malfunction— Quezada 2020

This is a brief audio review. In the article Reliability of the radiopharmaceutical shunt flow study for the detection of a CSF shunt malfunction in the presence of stable ventricular size published, 2020 by Quezada and Colleagues, The outcomes and key points are as noted: Radiopharmaceutical shunt studies help provide information to make operative decisions in patients with symptoms of ventricular shunt malfunction with no neuroimaging signs of ventricular change. Flow study interpretation correlated with increased rates of revision since the flow study increased the specificity of ventricular shunt malfunction 92% to 100% compared with magnetic resonance imaging, computed tomography. Odds ratio 27, P<0.0001. This was a Retrospective, [cross sectional] with 119 patients who were patients who were children admitted to Children's Hospital of Los Angeles between 2014 to 2019 whose neuroimaging (in the form of magnetic resonance imaging or computed tomography) did no show ventriculodynamic changes.
