A Case of Coarctation of Descending Mid-Thoracic Aorta Caused by Fibromuscular Dysplasia / 日本心臓血管外科学会雑誌

ABSTRACT

A rare case of descending thoracic aortic coarctation caused by fibromuscular dysplasia is reported. A 74-year-old woman was referred to our institution because of congestive heart failure, hypertension, acute renal failure and pressure gradient between upper and lower extremities. Aortography revealed 90% stenosis of the descending mid-thoracic aorta. Descending-descending aortic bypass was performed under femoro-femoral partial cardiopulmonary bypass. The post-operative course was uneventful and the pressure gradient across the coarctation was disappeared. The patient discharged on the 28th postoperative day without any problems. The pathohistological findings revealed fibromuscular dysplasia in the media and intima of the aortic wall.
