[Therapeutic strategies for acute type A aortic dissection].
We herein present the early and mid-term outcomes of therapeutic strategies for acute type A aortic dissection in our department. Subjects were 75 patients who were admitted to our department from January 2001 to October 2006. A total of 33 patients had thrombosed dissection: emergent surgery was indicated for cases in which the maximal ascending aortic diameter was > or =50 mm or when ulcer-like projection (ULP) was observed in the ascending aorta. Only 1 case of rupture-related death was observed, in a patient who had a maximal ascending aortic diameter of 52 mm and refused surgery. Although 8 patients were converted to surgery during the chronic phase, elective surgery was recommended in all cases. Surgery consisted of entry resection using open distal anastomosis under circulatory arrest at a bladder temperature of 25 degrees C, with antegrade cerebral perfusion into the 3 cervical branches of arch aorta based on bilateral axillary artery. In-hospital mortality of the 62 patients who underwent surgery was low (4.8%) and no dissection-related deaths were reported for the midterm outcomes. In addition, a low rate of cerebral infarction was observed among cases who had residual dissection of the brachiocephalic arteries after surgery. These findings demonstrate the validity of the therapeutic strategies in our department.
