We present a case of 30-year-old man with successful bypass grafting for coarctation of the aorta. Hypertension was identified during a health examination. Blood pressure difference between the upper and lower limbs was about 60 mmHg. Computed tomography( CT) revealed stenosis of the distal aortic arch and development of collateral arteries. The pressure gradient across the coarctation by catheterization was 56 mmHg. After left thoracotomy through the 4th intercostal space, a bypass graft using a 14-mm woven Dacron graft was placed between the left subclavian artery and descending aorta without the use of extracorporeal circulation. Postoperative course was satisfactory, with minimal pressure difference between the upper and lower extremities. The patient was discharged 16 days postoperatively. As of 7 years later, he remains asymptomatic, and CT has revealed no marked changes of the aorta or bypass graft.
