Sclerotherapy for Management of Intrathecal Pump Seroma Formation: A Case Series.

Background: Intrathecal drug delivery systems (ITDDS) are an option for the treatment of chronic pain syndromes or spasticity that are refractory to other conservative measures; however, they are not without complications. Seroma formation is one of the possible complications following implantation of an ITDDS.

Case report: We present 3 separate cases of patients with recalcitrant seroma formation at their IT pump sites that were successfully treated with doxycycline pleurodesis.

Conclusions: Pump site seroma formation is a possible complication following implantation of an ITDDS. Typically, these are self-limiting, but if not addressed can result in complications which include pain, infection, and difficulty filling. We propose a case series of 3 patients who suffered from recurrent seroma formation following ITDDS implantation that were successfully treated with doxycycline-based sclerotherapy.
