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).
