case_images: Computed tomography angiogram of the chest, abdomen, and pelvis with runoff revealed an isolated right sided saccular 2.6-cm EIA aneurysm above the inguinal ligament, with no extension proximally or distally (Fig 1, A-C).
case_images: Intraoperative angiography. (A) Preoperative aortogram. (B) Preoperative iliac angiogram. (C) Completion angiogram after stent graft deployment. (D) Reconstructed three-dimensional image of 2-week follow-up computed tomography scan showing completely excluded aneurysm with patent stent graft in suprainguinal right external iliac artery (EIA).

case_images: An aortogram was captured (Fig 2, A and B) to visualize the iliac arteries with an oblique view to visualize the right hypogastric takeoff. A widely patent bilateral iliac system was visualized, and a large 2.6-m aneurysm was identified 4 cm above the femoral bifurcation. Final angiography (Fig 2, C) demonstrated widely patent right EIA and widely patent femoral bifurcation with complete exclusion of the EIA aneurysm. Postoperative computed tomography angiography demonstrated an excluded aneurysm sac with a good apposition of the stent graft with no evidence of endoleaks or stent graft-related complications (Fig 2, D).
