Stanford A 型急性大動脈解離に対する基部再建術の手術成績

We evaluated retrospectively 11 consecutive patients who underwent emergent aortic root operations for acute aortic dissection from April 2012 to March 2017. We underwent Bentall operation in 6 patients and Florida Sleeve repair in 3 patients and aortic root replacement with a Freestyle stentless porcine valve in 2 patients. The 30-day mortality of emergent aortic root operations was 9.1％（1 of 11）, and the hospital mortality was 18.2％（2 of 11）. The Overall survival at 5 years was 90.0％. In conclusion, the aortic root repair can be performed safely in acute aortic dissection.
