Limited evidence is available regarding the efficacy of surgical sympathectomy. Four open-label studies have reported some long-lasting benefits in treating both CRPS types I and II. [144, 145, 146, 147] The most important factor in obtaining a positive outcome is having the procedure take place within 12 months of the inciting event. [144, 146] An irreversible sympathectomy may be effective in select cases owing to the risk of developing adaptive supersensitivity, even on nociceptive neurons, and having a subsequent increase and prolongation of pain. However, these procedures should not be widely recommended. [59]
