Figure 2: CT angiogram (3D reconstruction): (a) anterior; (b) lateral. The abdominal aorta is occluded at T12 (thick arrow). Both internal mammary arteries are markedly enlarged and ramify with the inferior epigastric arteries (arrowheads). The renal arteries arise from collaterals inferior to the termination of the aorta. The left renal artery (thin arrow) is small and there is decreased enhancement of the anterior half of the left kidney.
