One-Stage Operation of Annulo Aortic Ectasia Complicated with Acute Aortic Dissection of Stanford Type B / 日本心臓血管外科学会雑誌

ABSTRACT

A 51-year-old man was admitted with symptoms of sudden back pain and abdominal pain. Echocardiography and aortagraphy demonstrated enlargement of the aortic annulus, aortic regurgitation and Stanford type B aortic dissection. Since an entry of the aortic dissection was located at the root of the left subclavian artery, a one-stage operation consisting of aortic root replacement and total arch replacement was scheduled. The aortic root replacement using Piehler's modification was first performed followed by total arch replacement combining with the closure of the entry in the distal aortic arch was followed under selective cerebral perfusion. All procedures were complished through median sternotomy. The postoperative course was uneventful and aortography showed good reconstruction of the coronary arteries and the cervical arteries and thrombo-exclusion of the false lumen in the descending aorta. This method was useful for in this case of annulo aortic ectasia with Stanford type B aortic dissection.
