Review Case Reports
Reflex sympathetic dystrophy treated by electroconvulsive therapy: intractable pain, depression, and bilateral electrode ECT.
An adult female patient without previous history of pain or psychiatric disorder developed reflex sympathetic dystrophy (RSD) in her left hand and arm after 2 separate injuries, and subsequent arthroscopy and arthroscopic surgery. Traditional management with systemic medications, nerve blocks, and behavioral pain management were unsuccessful. With subsequent development of depression and suicide attempt, electroconvulsive therapy (ECT) was administered using bilateral lead placement. ⋯ A review of the literature from the 1940s revealed numerous cases of chronic, intractable pain treated successfully by ECT, although none of the case series were controlled studies. More recent literature questions if 'modified' ECT, using unilateral lead placement, is less effective than bilateral lead placement, in treating pain syndromes. Resolution of the vascular changes of RSD after ECT raises questions of possible cerebral contributions to the pathophysiology of RSD.
