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
