Twenty-two (32.8%) of 67 patients who had patch graft aortoplasty for aortic coarctation underwent reoperation because of aneurysm formation opposite or at the site of the patch. The mean age at primary repair was 25.3 years (standard deviation, 9.5 years). Reoperation took place 12.3 years (standard deviation, 3.7 years) later. In 19 patients, the aneurysm was resected and the aorta reconstructed with a tubular prosthesis. In 3 patients, the aneurysm was given external support. There were no hospital deaths. Recurrent nerve paralysis (36%) and bleeding necessitating repeat thoracotomy (32%) were the most common complications. Mean follow-up was 4.6 years. No aneurysms developed at the site of reoperation. Two patients died of causes not related to reoperation. Reconstruction with a tubular prosthesis gives good long-term results in patients with aneurysm formation after patch grafting for coarctation. External support offers technical advantages in select patients. Close follow-up of patients who have coarctation repair with a patch graft is essential.
