Reoperation for aortic coarctation: techniques, results, and indications for various approaches.
To define the safety and efficacy of operation for recurrent thoracic aortic coarctation, we reviewed the hospital records and subsequent courses of 53 patients who underwent such procedures over a 23-year period. Previous operations included end-to-end anastomosis, prosthetic patch or subclavian flap aortoplasty, and prosthetic interposition or bypass grafts, performed in patients ranging from 1 day to 44 years old. Several different reoperative procedures were used, including an ascending-descending aortic bypass graft in 4 patients who had had two previous repairs. There were no hospital or late deaths and only 3 relatively minor complications. Only 2 patients have hypertension requiring drug therapy at follow-up, which now averages 7 years. We conclude that operative management of severe, recurrent coarctation is both safe and effective, and that several techniques of reconstruction may have a place in such therapy.
