Reconsideration and surgical technique report of root repair management of acute Stanford type A aortic dissection.

Currently, there is a lack of expert consensus and clinical guidelines about the treatment strategy for aortic roots in patients with acute Stanford type A aortic dissection with aortic sinuses less than 45 mm in diameter and without combined connective tissue disorder. The physiological aortic sinus plays a key role in the protection of the aortic valve and cardiac function. Thus, we invented a "watching without dealing with" technique of aortic root repair to preserve the aortic sinus as much as possible. This technique could simplify the operation and improve the patient's prognosis, which is worth learning and promoting.
