Axilloaxillary bypass: is it worthwhile?
To evaluate the efficacy and long-term patency results of axilloaxillary bypass, a review of 32 patients with follow-up extending to 11 years was done. Twenty-two bypasses were performed for vertebrobasilar symptoms or subclavian steal and 10 for upper extremity claudication and/or ischemia. The mean age of the operative group was 66 years, 94% of patients had more than one atherosclerotic risk factor (hypertension, diabetes, coronary artery disease, smoking), and 75% had undergone a previous arterial reconstruction operation. There were no operative deaths, and the only postoperative complication was a sterile seroma which responded to aspiration. At late follow-up extending to 11 years, three grafts had thrombosed while another became infected and had to be removed; no limb loss resulted from these graft failures and the actual late patency rate was 87%. Carotid-subclavian bypass, intrathoracic bypasses, and endarterectomy at the site of occlusion have all been suggested for the treatment of symptomatic proximal subclavian artery disease. With axilloaxillary bypass, however, the hazards associated with carotid artery manipulation, operation on the notoriously treacherous subclavian artery, and the morbidity related to thoracotomy in this older, high-risk patient population can be avoided. The axilloaxillary bypass is safe and simple, and the excellent long-term patency rates make it the procedure of choice for symptomatic subclavian artery disease.
