    Abstract:
    BACKGROUND: Bypass grafting for complex forms of coarctation has been poorly documented as an alternative to decrease the high complication rate associated with anatomic repair. METHODS: Between mid-1980 and the end of 1994, 16 patients underwent bypass grafting for complex forms of isthmic aortic coarctation. Age ranged from 11 to 49 years (mean age, 28.4 +/- 13 years). Indications were atypical anatomic forms of coarctation (n = 12) and reoperation after multiple or complicated previous coarctation repair (n = 4). Lateroisthmic bypass grafts were performed in 14 patients and ascending aorta-descending aorta bypass grafts in 2. RESULTS: There was no hospital mortality. Morbidity consisted of postoperative paradoxical hypertension in 3 patients. There were no spinal cord complications. One death 10 years postoperatively was unrelated to the surgical technique. One patient successfully underwent ascending aorta-descending aorta bypass grafting for a false aneurysm 10 years after lateroisthmic grafting. All patients were asymptomatic and all grafts, patent after a mean follow-up of 5.7 +/- 4 years. CONCLUSIONS: On the basis of these results, bypass grafting appears to be a safe alternative in this select group of patients. The lateroisthmic bypass graft is the procedure of first choice, and the ascending aorta-descending aorta bypass graft should be reserved for failure of previous lateroisthmic bypass grafting.
