[Up to Date for Treatment of Stanford Type A Acute Aortic Dissection]

Surgical outcomes for acute type A aortic dissection (ATAAD) have been improving, but mortality rate remains about 10% in the last decade. Based on the current literatures including American Association for Thoracic Surgery (AATS) expert consensus, we presented the latest treatments and our surgical strategies for ATAAD. This section states about cannulation strategies for cardio-pulmonary bypass, aortic root managements, aggressive arch strategies, distal anastomosis strategies and the managements of malperfusion syndrome. We recommended the ascending aorta using the Seldinger technique as the cannulation site. As the aortic root management, valve resuspension is effective, but valve-sparing aortic root repair may be an option for young patients with annulo-aortic ectasia, intimal tear located in Valsalva sinus or Valsalva sinus rupture. The tear-oriented surgery is the standard for the range of the graft replacement, however, aggressive arch repair is also good indication for young patients. Distal anastomoses are felt sandwich technique for hemi-arch replacement or partial arch replacement and frozen elephant trunk is useful to total arch replacement. Early reperfusion strategies were important to the malperfusion syndrome of coronary arteries, supra-aortic vessels and superior mesenteric artery. To the dissected common carotid arteries (CCAs), early reperfusion and direct reconstruction of CCAs were effective.
