The The Lupiae TechniqueLupiae Technique in Type A aortic dissection with in Type A aortic dissection with
complicated false lumen achieves complicated false lumen achieves 2 2 important targets:important targets:
1.1. ““Easy”Easy” replacement of dissected ascending aorta replacement of dissected ascending aorta
