The changes on computed tomography angiography between admission and after thoracic endovascular aortic repair (TEVAR). a On admission: a penetrating atherosclerotic ulcer (PAU, purple arrow) located in descending aorta, the ascending aortic intramural hematoma (blue arrow) and pericardial effusion (brown arrow). b 2 weeks after TEVAR: PAU was excluded but the maximal ascending aortic diameter (MAAD) and the maximal ascending aortic hematoma thickness (MAHT, blue arrow) increased, and the pericardial effusion (brown arrow) and pleural effusion progressed. c 3 months after TEVAR: the MAAD decreased with the MAHT (blue arrow), the pericardial effusion (brown arrow) and the pleural effusion nearly disappearing. d 2 weeks after TEVAR: an aortic arch dissection (red arrow) distal to ascending aorta occurred. e 3 months after TEVAR: the aortic arch dissection (red arrow) stabilized. f 3 months after TEVAR: a dissection was confined within the aortic arch
