BACKGROUND: Complex regional pain syndrome (CRPS) is a condition characterized by the development of spontaneous pain with features of allodynia; hyperalgesia; vasomotor, sudomotor, and trophic changes; as well as motor dysfunction. For lower extremity symptoms, the primary sympathetic intervention is the lumbar sympathetic block (LSB). There are several complications associated with the procedure including paraplegia, especially in the setting of neurolysis.
CASE REPORT: In this case, we describe a patient who underwent a successful LSB with local anesthetic resulting in 4 days of transient lower extremity paraplegia and subsequent complete resolution.
CONCLUSION: It is essential to understand that this is a potential complication of LSBs in patients with CRPS once all other explanations have been ruled out and that the symptoms will resolve with supportive care.
KEY WORDS: Complex regional pain syndrome, lumbar sympathetic block, sympathetic mediated pain, transient paraplegia, case report
