[Thoracic Endovascular Aortic Repair for Stanford Type B Acute Aortic Dissection with Right Leg Malperfusion:Report of a Case].

We report a case of complicated Stanford type B acute aortic dissection with malperfusion to the right leg. The patient received conservative treatment in a previous hospital. However, he complained of pain in the right leg, which had been gradually turning pale. The patient was diagnosed with complicated Stanford type B acute aortic dissection with right leg malperfusion and was transferred to our hospital for treatment. Thoracic endovascular aortic repair (TEVAR) to close the entry to the distal aortic arch was performed, and we embolized the left subclavian artery to prevent type Ⅱ endoleak and to extend the stent-graft landing zone. We implanted a bare stent into the right external iliac artery to enlarge its true lumen. The patient was discharged from our hospital 22 days postoperatively. After the operation, computed tomography( CT) scan showed an aortic false lumen remodeling.
