B) Clinical Outcomes of Uncomplicated Type B Intramural
Hematomas
Sudden death occurred in six patients in the non-DM group (three
patients with signs of aortic rupture, one patient with aortic
pseudoaneurysm and one patient with retrograde type A aortic dissection)
and two patients died after receiving the thoracic endovascular aortic
repair (TEVAR) including one case of aortic rupture and one case of
retrograde type A aortic dissection. Only two patients underwent
conservative treatment because their symptoms were still controllable,
while the other eleven patients with uncontrollable symptoms underwent
TEVAR (one case of signs of aortic rupture, one case of aortic
pseudoaneurysm, two cases of aortic dissection and seven cases of
ulcer-like projection development). In the DM group, only one patient of
the four with disease progressions received TEVAR (one case of aortic
dissection) and other three patients with controllable symptoms received
conservative treatment
