Abstract
A 64-year-old woman with dyspnea on exertion was referred to our hospital. CT revealed type B aortic dissection with 7cm of aneurysm including a thrombus in the false lumen at the distal aortic arch. Four intimal tears at the distal aortic arch were closed directly during hypothermic circulatory arrest, and the descending thoracic aorta was tailored without a prosthetic graft after fixation of the dissecting adventitia to the intima at the distal portion of the false lumen. The postoperative course was uneventful and this patient was discharged on the 22nd postoperative day. Three years after surgery, the postoperative CT revealed no evidence of dilatation of the descending thoracic aorta as far as the abdominal aorta although the dissection of thoracoabdominal aorta remained. This technique is effective as an surgical option for chronic type B aortic dissection to minimize operative stress and complications.
