[Coarctation of aorta with right aortic arch and anomalous left subclavian artery].
The occurrence of coarctation in patients with right aortic arch is extremely rare. We have encountered a 21-year-old man with anomalous left subclavian artery. He was diagnosed when he was 13. On angiography he exhibited a right aortic arch. The left common carotid artery, right common carotid artery and the right subclavian artery diverged from the proximal side of the coarctation. The left subclavian artery diverged from the distal side. The right brachial arterial pressures measured 158-72 mmHg, while the left brachial arterial pressures measured 98-80 mmHg. Clinical studies revealed no vascular ring and no other anomalies were found in this patient. An attempt at treatment was made with extra anatomical bypass grafting from the ascending aorta to the descending aorta. No pressure difference due to coarctation remained after operation.
