Isotopic Scintigraphy in Intrathecal Drug Delivery Failure: A Single ‐Institution Case Series

ConclusionsTwenty ‐two abnormalities were identified in 21 examinations, with these abnormalities consisting of leakage (n = 7), spinal catheter obstruction (n = 7), and cerebrospinal fluid flow obstruction (n = 8). Interventions (n = 19) confirmed the cause of ITDD failure. A false ‐positive finding at follow‐up (n = 1) and a false ‐negative finding (n = 1) were encountered. Sensitivity was 95% (20/21) and the specificity 93% (14/15). A significant difference (p <  0.001) was found between the accuracy of the conventical and the optimized analysis. The optimized 111In ‐DTPA SPECT‐CT examination is a powerful diagnostic tool for detecting the cause of ITDD failure.
