A new operation for revascularizing the subclavian artery has been described in detail. The procedure involves creation of a subcutaneous axillary-axillary bypass. Three cases are presented in which the operation has successfully corrected the hemodynamic defect. The major disadvantages of carotid-subclavian bypass and direct endarterectomy of the subclavian or innominate arteries are obviated by axillary-axillary bypass. The procedure has a definite place in the management of patients with symptomatic occlusive lesions of the proximal subclavian and innominate arteries.
