CAROTID-AXILLARY ARTERY BYPASS - A 10-YEAR EXPERIENCE

Purpose: The purpose of this study was to review our 10-year experienc e with carotid-axillary artery bypass in the treatment of occlusive le sions of the proximal subclavian artery. Methods: Our 10-year experien ce with 26 carotid axillary bypasses for occlusive disease of the subc lavian artery was reviewed retrospectively. The review focused on the indication for the operation, the surgical technique used, and the dev elopment of immediate and late postoperative complications. Long-term bypass graft patency and clinical success were determined on the basis of information gleaned from the office records of all patients. Only three patients were lost to follow-up at 12, 36, and 38 months. Result s: There were no operative deaths. Two patients had small cervical wou nd hematomas, and two others experienced transient symptoms of brachia l plexus irritation, which subsided spontaneously. Permanent nerve or lymphatic complications did not occur. In a mean follow-up of 47 month s, carotid-axillary bypass graft patency was 96%, and 88% of the patie nts enjoyed symptom-free sustained clinical success. Conclusions: This retrospective review demonstrates that a carotid-axillary bypass cons tructed with ringed synthetic graft material tunneled under the clavic le performs well and can be considered a reasonable alternative to the more standard carotid-subclavian bypass for the same indications.
