Figure 4. Anteroposterior plain radiograph showing a bifurcated stent-graft. There are radio-opaque markers at the top and bottom of the short limb of this bifurcated device (solid arrows). The third pair of radio-opaque markers is at the top of the limb (open arrow), which has been introduced from the right groin to overlap this short leg, completing the bifurcated device. Embolisation coils can be seen at the origin of the inferior mesenteric artery (curved arrow).
