Aortic emergencies are surgically challenging and the mortality rate remains high.
Since December 2003, we have performed endovascular treatment with a stent graft（EVT）in 15 cases of aortic emergency, including 8 cases of aortic rupture or traumatic aortic disruption, 1 case of traumatic iliac artery disruption, 3 cases of aortobronchial fistula（ABF), and 3 cases of aortoenteric fistula（AEF).
In 9 cases of aortic rupture and traumatic aortic or iliac disruption, 1 patient died due to traumatic cerebral hemorrhage, but the remaining 8 patients were discharged without complications.
While hemoptysis was resolved in all 3 patients with ABF, 1 patient with primary ABF died due to pneumonia, and 1 patient with secondary ABF died due to multiple organ failure.
Furthermore, 1 patient with primary AEF progressed well without any evidence of postprocedural stent graft infection.
In 2 patients with secondary AEF, both required secondary surgical graft excision, and 1 of these died due to the recurrence of infection.
EVT has shown good results in hemostasis for aortic emergency. However, if a source of infection persists, secondary surgical intervention is required in some cases.
Commercially available endovascular stent graft make it possible to treat tortuous segments of the thoracic aorta and the abdominal aorta, therefore we expect there to be more patients with aortic emergencies who require EVT.
