Abstract
OBJECTIVE: The surgical treatment of recurrent coarctation in adults supposes a redo left thoracotomy with adhesions and high risk of bleeding and injury of adjacent nerves. The rate of paraplegia in these cases may reach 2.6%. Extra-anatomic aortic bypass avoids these complications. We present our results with ascending-to-abdominal aorta extra-anatomic bypass for recurrent aortic coarctation in adults. METHODS: Between September 1979 and November 2006 12 patients underwent ascending-to-abdominal aorta bypass. There were 10 males and 2 females. Mean age was 36.2+/-11.3 (range 21-57) years old. Mean age at primary repair was 14.3+/-4.2 years old (range 8-21). Operative technique consisted of performing an ascending-to-abdominal aorta bypass via median sternotomy extended into the epigastrium with a supra-umbilical laparotomy through the mid-line abdominal fascia. Concomitant procedures were performed in six patients: three isolated aortic valve replacements (AVR), two ascending aorta graft replacements and one AVR associated with coronary artery bypass graft (CABG). RESULTS: No postoperative mortality was observed. Mean follow-up time was 10.4+/-9.3 years (range 0.3-27.8). No patients had any graft-related complication or death and all grafts were patent at the end of the follow-up. One patient developed a dilated myocardiopathy, dying at 14 years of follow-up. Four patients had persistence of arterial hypertension controlled with one drug therapy and five patients were asymptomatic. CONCLUSIONS: Ascending-to-abdominal aorta extra-anatomic bypass is a safe, effective and less invasive technique for aortic recoarctation in adults with good results at long-term.
