[Abstract]Acute type A aortic dissection is a lethal disease that requires immediate surgical intervention and lifesaving measures. The treatment of this condition primarily involves addressing the complex structure and vital role of the aortic root. Since 1968, surgical techniques for Aortic dissection type A have rapidly advanced, resulting in significantly improved patient outcomes. In recent years, various approaches to aortic root management have emerged. This article provides a comprehensive overview of these approaches.
