Abnormal Granuloma Formation in Intrathecal Pain Pump

Thursday, November 13, 2025
5:41 PM - 5:49 PM CT
Location: Griffin Hall - Screen 05
Introduction: Intrathecal pain pumps are used to deliver medications directly to the spinal intrathecal space to provide optimal analgesia1. However, the rare prevalence of granuloma formation on the catheter tip can lead to severe neurological damage such as paresthesias2. In a retrospective trial of 13 patients, the average onset of granuloma formation was 6.9 years3.

Though granuloma formation is associated with high dose opioids, research is absent on granulomas from anti-spasmodic medications or microdosed multidrug admixtures.
