case_images: Contrast computed tomography image taken 32 years after artificial blood vessel replacement surgery in which a covered stent was placed inside the artificial blood vessel.. (A) An artificial vascular leg was identified in the abdominal aorta sac, and a covered stent was implanted. (B) Volume rendering image. The abdominal aorta had been replaced by an artificial covered stent.

case_images: At 80 years of age, covered stents were placed bilaterally in the graft limbs (Figure 2).
case_images: Contrast computed tomography image taken 37 years after artificial blood vessel replacement surgery in which a covered stent was placed inside the artificial blood vessel.. (A) Volume rendering image. (B) A leak from an artificial blood vessel is visible at the proximal site. (C) A leak is visible at the end of the leg of the covered stent. (D) A leak from the artificial blood vessel is visible at the end of the artificial blood vessel.

case_images: Despite this intervention, the abdominal aortic sac gradually enlarged over time (Figure 3).
case_images: Intraoperative images taken during endovascular treatment.. (A) Pre-angiography image revealing no leakage. (B) Aortic cuff placed at the proximal site (green arrow). (C) Post-angiography image revealing no leakage. The central anastomosis and distal anastomosis are covered by a stent graft.

case_images: Contrast computed tomography image taken after endovascular therapy.. (A) Volume rendering image. (B) No leak from an artificial blood vessel is visible at the proximal site. (C) Middle portion. (D) Distal site.
