Occlusion of a ventriculoperitoneal shunt system is potentially life-threatening complication in patients suffering from hydrocephalus. However, there no imaging established as standard approach this acute setting. In the present study, we evaluate use superb microvascular for investigation patency systems. Simulation low flow rates cerebrospinal fluid through small diameter CSF was performed dedicated phantom order to proof principle (SMI) being feasible measurement slow system. SMI able detect systems effectively and fast. Visualization Duplex ultrasound Doppler wave pattern VP after reservoir has been pressed confirms patency. an effective method evaluating diagnosing obstruction. This bears potential facilitate evaluation clinically symptomatic Further patterns granted.
