title: Descending aorta-external iliac artery bypass for middle aortic syndrome.
abstract: We encountered a surgical case of middle aortic syndrome (MAS) in a 56-year-old man who had resistant hypertension. Computed tomography showed severe stenosis of the abdominal aorta from below the superior mesenteric artery to above the inferior mesenteric artery. Although bilateral renal artery stenosis was confirmed, renal function was within normal limits. A 10-mm vascular prosthetic graft was used to perform a descending aorta to left external iliac artery bypass. His hypertension was well controlled without medication. This extra-anatomic bypass may be a simple and useful approach for treating MAS if it is not necessary to reconstruct the renal artery or visceral artery.
