Limited vs. extended repair for acute type I aortic dissection: long-term outcomes over a decade in Beijing Anzhen Hospital

To the Editor:For patients with acute DeBakey type laortic dissection,ascending aortic or hemiarch replacement can reduce the surgical time and save lives in critical situations.However,residual distal dissection increases the risk of dilatation,rupture,and death.[1] In contrast,total aortic arch replacement(TAR)with frozen elephant trunk(FET)implantation can minimize the need for re-intervention,[2] but may increase the risk of operative mortality,stroke,paraplegia,and other complications.Currently,the ques-tion of the optimal surgical strategy for acute DeBakey type I aortic dissection remains controversial owing to the scarcity of long-term follow-up data and the technical diversities among different institutions.
