Abstract：Acute aortic syndrome (AAS) is a cardiovascular emergency characterized by the disruption of the integrity of the aortic wall, including aortic dissection, intramural hematoma, and penetrating aortic ulcer, which can involve any segment of the aorta. Once it occurs, the mortality rate is extremely high. Currently, emergency surgery is the preferred treatment for AAS, but patients who are about to undergo surgery or cannot undergo surgery for various reasons should also receive non-surgical treatment. Although international guidelines recommend non-surgical treatment strategies for AAS, the details are limited, especially in terms of treatment strategies when organ perfusion is impaired, and the outcomes of different treatment strategies vary significantly, resulting in limited benefits for these patients. In addition, although there are expert consensuses on the diagnosis and treatment of hypertensive emergencies in China, they do not cover the management of complications involving impaired organ perfusion. Therefore, led by the National Clinical Research Center for Cardiovascular Diseases and Beijing Anzhen Hospital, Capital Medical University, together with the Chinese Society of Cardiovascular Surgeons and the Chinese Society of Emergency Medicine, an expert working group was established. Based on the principle of multidisciplinary collaboration and comprehensive rescue, involving departments such as emergency medicine, critical care medicine, cardiac and vascular surgery, peripheral vascular surgery, neurology, gastroenterology, nephrology, and orthopedics, this consensus was developed by referring to relevant guidelines, consensuses, and literature at home and abroad, combined with China's clinical practice, to establish a standardized and normalized non-surgical intensive treatment protocol for AAS. The aim is to provide comprehensive, multi-dimensional, and precise guidance for the implementation of non-surgical treatment, thereby improving the prognosis of patients with AAS.
