Introduction:
Oversizing of a stent graft limb is one of the risk factors for limb graft occlusion after endovascular aneurysm repair (EVAR) for abdominal aortic and iliac artery aneurysms. We report a case of common iliac artery (CIA) aneurysm with a shrunken external iliac artery (EIA) treated with a Gore C3 Excluder (W. L. Gore & Associates, Flagstaff, AZ, USA) and VBX (W. L. Gore & Associates).
Case Presentation:
A 76-year-old man was incidentally diagnosed with a right CIA aneurysm (diameter = 55 mm) on CT examination. He had a history of spinal cord injury at the age of 33 years, which paralyzed the lower part of his body. Owing to disuse atrophy, his right EIA became smaller with a diameter of 5 mm. The patient was treated with a Gore Excluder C3, and to prevent oversizing of the distal landing zone, a 6-mm VBX was used as the right stent graft limb. The postoperative course was uneventful, and 1 year after EVAR, the stent graft limb was patent.
Conclusions:
This case report describes successful endovascular treatment using Excluder C3 and VBX for CIA aneurysm with a shrunken EIA. In the case of a small-caliber EIA, the use of VBX may help avoid oversizing of the stent graft limb, which may prevent stent graft limb occlusion.
