AbstractA 51-year-old man was transferred to our hospital on an emergency basis complaining of a sudden onset of severe left lumbar back pain. An emergency contrasted computed tomography showed a ruptured thoracoabdominal aortic aneurysm( rTAAA:Crawford classification type III). The ruptured site was near the aortic bifurcation, and the aneurysm had a relatively narrow segment with an extensive mural thrombus just below the renal arteries. Considering the high mortality of open surgery for the rTAAA and the poor general condition of the patient, we decided to perform endovascular aneurysm repair (EVAR) as a rescue procedure using the narrowed segment by the thrombus for a proximal landing zone. The abdominal part of the thoracoabdominal aortic aneurysm (TAAA) was successfully excluded with a stent graft to obtain complete hemostasis. The postoperative course was uneventful except for the need for hemodialysis. Even though there is a risk of developing late type 1 endoleak, this procedure can be a feasible option as a rescue procedure or a bridge to radical open surgery for ruptured TAAA in a specially anatomical setting like this case.
