Surgical management of middle aortic syndrome in an adult.

Middle aortic syndrome (MAS), a coarctation of the lower thoracic and/or abdominal aorta, is typically diagnosed and treated in the pediatric population. We present a 48-year-old patient with a long-standing history of hypertension who was lost to follow-up owing to a lack of insurance coverage. After two myocardial infarcts owing to severe hypertension, a vascular workup including a computed tomography angiogram revealed a diagnosis of MAS. He underwent open vascular reconstruction with a thoracoabdominal Dacron bypass graft. He was discharged within 1 week with no hypertension or claudication. Adult patients diagnosed with MAS should undergo open or endovascular surgical repair with close follow-up.
