Guidelines for diagnosis and treatment of aortic aneurysm and aortic dissection were revised in 2020. Among them, I would explain the part of “epidemiology, pathology, definition, diagnosis and examination,” which have changed compared with previous guidelines; 1) Terminology: Intramural hematoma (IMH), Penetrating atherosclerotic ulcer (PAU), Ulcer-like projection (ULP) have been defined again. IMH was approved as clinical term in this guideline, which was not accepted in previous one. 2) Classification of aortic dissection according to status of false lumen: Upper limit size of ULP in ULP type was defined. 3) Risk classification of saccular aortic aneurysm: sac depth/neck width >0.8 was presented as one standard of high-risk saccular aneurysm.
