Case Reports
The treatment of upper extremity reflex sympathetic dystrophy with prolonged continuous stellate ganglion blockade.
Twenty-nine consecutively treated patients over a 5-year period with upper extremity reflex sympathetic dystrophy were admitted to Massachusetts General Hospital for prolonged continuous stellate ganglion blockade. Diagnosis was based on the presence of pain, decreased joint motion, trophic changes, and vasomotor disturbances. ⋯ Improvement during treatment was documented in all but two patients with regard to pain and decreased joint motion and in two-thirds with regard to trophic and vasomotor changes. Long-term follow-up demonstrated a relapse rate of 25%, but marked improvement persisted in the rest and normal status was attained in four of 26 patients at an average of 3 years later.
