Observational StudyLong-term outcomes of tear-oriented ascending/hemiarch replacements for acute type A aortic dissection.
Extended arch repair for acute type A aortic dissection remains controversial. Our strategy for acute type A aortic dissection was primary entry resection and tear-oriented ascending/hemiarch replacement for patients with the intimal tear in the ascending aorta or is not found in the ascending/aortic arch. Extended total/partial arch replacement was performed for patients with the tear located in the aortic arch. Here, we investigated the validity of our strategy from the viewpoints of long-term survival and reoperation. ⋯ We observed no significant differences in the actuarial survival or reoperation-free survival rates between the groups. These findings suggest that tear-oriented ascending/hemiarch replacement for acute type A aortic dissection does not increase the risk of long-term mortality or reoperation.
