[Expert consensus on diagnosis and treatment of acute aortic dissection with malperfusion syndrome (2026 edition)].

Malperfusion syndrome (MPS) is a life-threatening complication of acute aortic dissection (AAD). Current management of AAD with MPS faces challenges in early detection and revascularization strategies. To address these issues, the Thoracic Aortic Group,Vascular Surgeon Branch of Chinese Medical Doctor Association has developed this expert consensus based on the latest evidence. The consensus elaborates on the pathophysiology, epidemiology, diagnostic criteria and classifications of AAD with MPS, and proposes a stratified treatment strategy based on the ischemic organs and underlying mechanisms, aiming to standardize clinical practice and improve patient outcomes.
