BACKGROUND: We report a series of reoperations in 23 patients who had undergone previous aortic coarctation repair. METHODS: The medical records of these patients were reviewed, and the patients were followed up by telephone interview. Mean age at reoperation was 25 years. There was a mean of 18 years between initial coarctation repair and reoperation. Indications for reoperation included recoarctation (9 patients), aortic aneurysm (8), aortobronchial fistulas with exsanguinating hemorrhage (2), subaortic stenosis (1), ruptured thoracic aneurysm (1), ruptured sinus of Valsalva aneurysm (1), and supramitral stenosing ring (1). RESULTS: There were no specific intraoperative complications. Three patients required reexploration for bleeding. An acutely ischemic lower limb developed in 1 patient secondary to a common femoral artery embolus, which necessitated embolectomy. CONCLUSIONS: Reoperation for postcoarctation repair patients can be performed with good results. Sudden life-threatening hemorrhage due to aortobronchial fistulas in patients having undergone Dacron patch aortoplasty, as well as long-term obstructive phenomena seen anywhere along the left ventricular outflow tract, make lifelong surveillance of these patients mandatory.
