Figure 13. (a) There is a contrast blush arising from the anterolateral aspect of the aorta on the left (curved arrow) and a small area of calcification at this level. This is the origin of the inferior mesenteric artery. This is a type 2, side branch endoleak. There is also some peri-aneurysmal fibrosis (solid arrow), which has obstructed the right ureter (open arrow). (b) There is a faint blush between the limbs of the stent-graft (curved arrow) at the level of the left L4 lumbar artery (straight arrows). This was confirmed angiographically as a Type 2 lumbar endoleak.
