    B. S. HARHANGI, I. VOIGT, N. DAMEE, P. S. GADJRADJ. SMARTPHONE BASED THERMOGRAPHY TO DETERMINE SHUNT PATENCY IN PATIENTS WITH HYDROCEPHALUS. ACTA NEUROLOGICA BELGICA (2023). DOI: 10.107/S13760-023-02338-3. ABSTRACT BACKGROUND: WHEN SHUNT DYSFUNCTION IS SUSPECTED, RADIATION EXPOSURE DUE TO X-RAYS OR A CT-SCAN IS INEVITABLE. LESS-INVASIVE AND MORE RELIABLE METHODS ARE WARRANTED. IN THIS STUDY, WE AIMED TO ASSESS THE USABILITY OF SMARTPHONE-BASED THERMOGRAPHY TO DETECT SHUNT PATENCY IN PATIENTS WITH HYDROCEPHALUS. METHODS: THIS PROSPECTIVE OBSERVATIONAL PILOT STUDY EVALUATED THE USE OF SMARTPHONE-BASED VIDEO THERMOGRAPHY TO DETECT FLOW OF CEREBROSPINAL FLUID IN THE SHUNT OF 51 PATIENTS FROM THE DEPARTMENT OF NEUROSURGERY AT A TERTIARY REFERRAL INSTITUTE. PATIENTS WITH A SHUNT FOR HYDROCEPHALUS WITHOUT THE SUSPECT OF DYSFUNCTION WERE INCLUDED IN THE STUDY FROM DECEMBER 2021 TO MAY 2022. RESULTS: WE INCLUDED 51 PATIENTS WITH A MEAN AGE OF 53.3 YEARS. OF THESE PATIENTS 14 WERE MALE (27.5%) AND 37 WERE FEMALE (72.5%). THE MOST FREQUENT CAUSE OF THE HYDROCEPHALUS WAS THE NORMAL PRESSURE HYDROCEPHALUS FOLLOWED BY THE CONGENITAL HYDROCEPHALUS. MOST PATIENTS (96%) HAD A VENTRICULOPERITONEAL SHUNT, WHEREAS TWO HAD A VENTRICULO-ATRIAL SHUNT. IN TOTAL, 43 PATIENT (84%) HAD A SHUNT ON THE RIGHT SIDE AND 8 PATIENT (16%) HAD THE SHUNT LOCATED ON THE LEFT SIDE. IN 45 PATIENTS (88.2%), WE OBSERVED A CLEAR FLOW OF CEREBROSPINAL FLUID IN THE COOLED SHUNT TRAJECTORY. CONCLUSIONS: THE FINDINGS OF THIS STUDY INDICATE THAT IN PATIENTS WITH A SHUNT TO TREAT HYDROCEPHALUS, THE SMARTPHONE-BASED VIDEO THERMOGRAPHY MAY BE A SAFE AND SIMPLE ALTERNATIVE TO SHOW SHUNT PATENCY WITHOUT THE EXPOSURE TO RADIATION. REPORTED EVENTS: - IN 5 PATIENTS (9.8%), WE HAD SOME DOUBT ABOUT THE FLOW, AND IN ONE PATIENT (2%), THERE WAS NO FLOW VISIBLE AT ALL BUT WITHOUT SYMPTOMS OF SHUNT DYSFUNCTION.
