BackgroundAortic intramural hematoma constitutes one of the three classifications of acute aortic syndrome (AAS). Type B intramural hematoma (IMH-B) is localized to the descending thoracic aorta and can be managed through medical, endovascular or surgical means. Data comparing contemporary management with thoracic endovascular aortic repair (TEVAR) versus traditional medical management (MM) is sparse and only moderate strength recommendations for TEVAR are provided in guidelines. This meta-analysis aimed to pool available data from comparative studies between TEVAR and MM and examine differences in outcomes.
