The intrathecal drug delivery system (ITDDS), an effective treatment tool for intractable spasticity and pain, is associated with various complications but breakage of the catheter is rare. We report the case of a 50-yr-old man with ITDDS, in whom an intrathecal catheter was severed, resulting in a 28.6-cm-long intrathecal fragment. The catheter completely retracted into the intrathecal space from the anchor site. The catheter was severed during spine flexion, and the total distal fragment was repositioned in the intrathecal space. Although the outcome of ITDDS was associated with the length or diameter of the broken catheter, no neurologic complications occurred in our patient. Thus, we inserted another catheter instead of removing the old one. Thereafter, the patient has been regularly followed up, and no neurologic complications have developed during the 28 months.

This report describes the long term safety and efficacy of intrathecal therapy using Sufentanil for the management of chronic intractable neuropathic pain in 12 chronic pain patients. Standardized psychological screening was used to determine treatment suitability. Evaluation data included the Visual Analog Scale (VAS), Wong-Baker Faces Scale, Brief Pain Inventory (BPI), Disability of Arm, Shoulder, and Hand (DASH), McGill Quality of Life Questionnaire, and complications (granulomas, toxicity, withdrawal, or deaths). SPSS version 18 was used for data analysis. Pre- and post- treatment BPI measures and pain scale scores showed a statistically significant difference. There were no complications directly related to drug toxicity, nor drug withdrawals, granulomas, or deaths. Intrathecal therapy with Sufentanil therapy offers a good treatment alternative for those cases that have failed both surgery and standard pain treatment. Strict patient selection based on psychological screening, control of co-morbidities, a proper pain management may contribute to successful outcome.
