Disputal percutaneal palette replacement technique for medular stimulation as a treatment of refractory chronic pain patient without Schawannoma L2 left: case report

Abstract

Introduction: Spinal cord stimulation systems can use percutaneous electrodes or percutaneous (PP) paddles, unlike surgical paddles that require a surgical approach for implantation by laminotomy or laminectomy. To date, there are no reports in the world literature regarding percutaneous withdrawal of dysfunctional (PP). Materials and Methods: It is a case report, descriptive and retrospective. Who required implantation of implanted medullary neurostimulator (NEMI) with (PP) for refractory chronic neuropathic pain, who attended with dysfunction and later candidate for replacement of the (PP) with percutaneous technique. Performed in service of Pain Clinic of the National Medical Center "November 20" in September 2016. Results: A 54-year-old female with a diagnosis of Schwannoma of the left L2 root who presented dysfunction of the (PP) of the (NEMI) during an automobile accident. A percutaneous approach is performed in a fluoroscopy room using the Epiducer TM of ST. Jude Medical as a "bridge" for the removal of the dysfunctional (PP) and replacement of the new (PP) without conducting a laminotomy or laminectomy approach. Conclusions: The percutaneous approach to replacement of (PP) is an effective minimally invasive technique, with a lower probability of complications and without the need for laminectomy or laminotomy.
