BACKGROUND: Bypass grafting for repeat operation or complex forms of descending aortic disease is an alternative approach to decrease potential complications of anatomic repair. METHODS: Between December 1985 and February 1998, 17 patients (13 men, 4 women; mean age, 47.6 +/- 18.5 years) underwent ascending aorta-to-descending aorta bypass through a median sternotomy and posterior pericardial approach. Indications for operation were coarctation or recoarctation of aorta in 8 patients, Takayasu's aortitis in 2, prosthetic aortic valve stenosis associated with coarctation of aorta, complex descending aortic arch aneurysm, reoperation for chronic descending aortic dissection, long-segment stenosis of descending aorta, acquired coarctation after repair of traumatic transection of descending aorta, severe aortic atherosclerosis, and false aneurysm of descending aorta after repair of coarctation in 1 patient each. Concomitant procedures were performed in 12 patients. RESULTS: No early or late mortality has occurred. Follow-up was 100% complete and extended to 12 years (mean, 2.7 +/- 3.3 years). No late graft-related complications have occurred; 1 patient had successful repair of perivalvular leak after mitral valve replacement, and 1 patient had replacement of lower descending and abdominal aorta. CONCLUSIONS: Exposure of the descending aorta through the posterior pericardium for ascending aorta-descending aorta bypass is a safe alternative and particularly useful when simultaneous intracardiac repair is necessary.
