Management of acute ischemia of the upper extremity.

Records of 76 patients who presented with ischemia of the upper extremity from 1966 to 1981 were reviewed. Patients were divided into three groups according to cause: Group 1, emboli from the artery; Group 2, ischemia after catheter injury; and Group 3, ischemia due to lesions of the axillary and subclavian arteries. Management varied among the three groups. Long-term anticoagulation therapy was helpful in Group 1 patients in preventing reembolization. Forty percent of patients with catheter-related trauma required angioplasty of some sort in addition to embolectomy. Management of Group 3 patients was most difficult and the results least acceptable (three patients required amputation). Management of this type of ischemia must be individualized; it should vary according to the underlying disorder.
