Lower body ischemia due to bending of a stented graft at the thoracic aorta was rare, particularly when it occurred in several days after surgery. We experienced this complication and performed the 3rd-time thoracic endovascular repair( TEVAR).A 49-year-old man with a chronic aortic dissection of Stanford type B underwent TEVER;however we failed to close the entry because of the tortuously bended distal arch of the aorta. Then it was decided the patient undergo a hybrid treatment with arch replacement and frozen elephant trunk. Seventeen days after the surgery, the blood pressure of the patient's lower limb was reduced rapidly and his renal function deteriorated. Bending of the stent was revealed by computed tomography( CT). The patient underwent the 3rd-time emergency TEVAR, and his symptoms improved.
