Open repair of adult aortic coarctation mostly by a resection and graft replacement technique

Abstract

We report on our experience with treatment of adults requiring de novo or redo open aortic coarctation repair mostly by a resection and interposition graft technique. We retrospectively reviewed all patients older than 16 years requiring open repair of aortic coarctation. Indications for repair, operative details, and outcomes were analyzed. Between 1996 and 2011, we treated 29 adult aortic coarctation patients with open repair. The mean age was 42 years (range, 17-69 years), and there were 15 men. Nine patients had previous repair with recurrence; the remaining 20 had native coarctation. Thoracic aortic aneurysms were present in 22 patients (76%), ranging in size from 3.0 to 9.6 cm (mean, 4.8 cm). Four patients had intercostal artery aneurysms (range, 1.0-2.5 cm), four had left subclavian artery aneurysms, and four had ascending/arch aneurysms. The most common repair was resection of aortic coarctation with interposition graft replacement (93%). Two patients without aneurysm had bypasses from the proximal descending thoracic aorta to the infrarenal aorta without aortic resection. There was no in-hospital mortality, stroke, or paraplegia. Long-term survival was 89% during a median follow-up of 81 months (interquartile range, 47-118 months), with no patient requiring reoperation on the repaired segment. Open repair of native and recurrent adult aortic coarctation has acceptable morbidity and low mortality. Especially in patients with concomitant aneurysm, resection with interposition graft replacement provides a safe and durable repair option.
