Ascending aorta-abdominal aorta bypass with the reconstruction of superior mesenteric and bilateral renal arteries for mid-aortic syndrome

Abstract

We report the surgical repair of a case of mid-aortic syndrome (MAS) in a 17-year-old female patient. She was initially diagnosed with renovascular hypertension at the age of 12 years. Aortitis syndrome was suspected, and she has been treated with antihypertensive drugs since then. Angiography revealed severe stenosis of the abdominal aorta and left renal artery and occlusion of the right renal artery and superior mesenteric artery (SMA); this confirmed the diagnosis of MAS. Due to progressive, uncontrollable hypertension, we performed an ascending aorta-abdominal aorta bypass with revascularization of SMA and both renal arteries. Her blood pressure normalized following the operation.
