(A) Coronal abdominal aortic aneurysm image shows an 18 × 9 cm Gelweave bifurcated graft (Terumo) anastomosed from the infrarenal aorta to both iliac arteries; (B) axial maximum intensity projection image reveals the ligated preaortic branch and hypertrophied retroaortic branch of the left renal vein.
