Supplement 3 Evolutions of Type A Intramural Hematoma
The orange arrows indicate the process of evolution, and the red arrows indicate the lesion.A) In the diabetes mellitus (DM) group, the hematoma could be completely absorbed after medical treatment; B) The development of an ulcer-like projection (ULP) was identified during the acute phase and the ULP disappeared in the chronic phase, indicating that this patient was free from receiving thoracic endovascular aortic repair (TEVAR) treatment. C) This patient received open surgery during the follow-up period because of hematoma thickening during the chronic phase (> 90 days) and ULPs appeared in different areas of the aortic wall combined with refractory back pain. D-G) In the no DM group, four patients died of a ruptured ascending aortic pseudoaneurysm (D, E and G) or retrograde type A aortic dissection (F) after receiving TEVAR in the subacute phase (15-90 days).
