A Rare Intrathecal Pump Complication Caused by Prolonged Seroma Leading to a Potential Pump Pocket Fill: A Near Miss.

Intrathecal drug delivery systems have been used with increasing frequency in patients with chronic intractable pain. Common complications of intrathecal drug delivery systems include surgical bleeding, spinal cord injury, fractured or migrated catheter, meningitis, pump failure, granuloma formation, cerebral spinal fluid leak, and hygroma formation. We present a rare near-miss case that could have led to the inadvertent filling of an intrathecal pump pocket with a high concentration of narcotic and local anesthetic. This situation arose due to the discovery of a prolonged intrathecal pump pocket seroma during a routine maintenance and refill procedure.
