[Current indications for superior dorsal sympathectomy. Apropos of 84 cases].

Results of dorsal sympathectomy in patients (67 operations) for vasomotor disorders of the upper limbs were assessed after follow-up for between 6 months and 15 years, in order to determine the best indications for surgery. Based on clinical results, sympathectomy should be performed not only when medical treatment fails, but also in the presence of a severe clinical picture of trophic disturbances or pain of the ischemic type. Two types of investigation are essential before deciding on operative therapy:--plethysmography with a hyperemia test,--arteriography of the hand. Assessment of results as a function of etiology demonstrated that they were excellent in cases of hyperhidrosis, very satisfactory in atheromatous digital arteritis or a thoracic inlet syndrome (associated with rib resection in the latter case), but only moderately good in scleroderma or post-traumatic lesions. Finally, Raynaud's disease or thromboangiitis do not appear to be indications for this operative procedure.
