Explantation of aortic infrarenal stent graft

end of the stent graft is extracted from the aorta. If another graft is used, proximal anastomosis is carried out with the balloon inflated. To complete the anastomosis a second Foley catheter is passed through a limb of the new graft (Fig 2). While the original catheter is deflated and removed, the second balloon is inflated in the suprarenal aorta (Fig 3) and the anastomosis completed. ACKNOWLEDGEMENT We would like to thank James Clark for his help with the drawings. TECHNIQUE Pass a drill guide through the jig used for inserting proximal screws. Leave the drill guide in position against the limb. This can now be used to align the C-arm. Position the C-arm distally and adjust its position until it is parallel to the drill guide in its orbital and swivel axis. This will give near perfect alignment to the distal locking holes. Finer adjustments may be needed under image intensifier guidance to gain the final position. Once satisfactory alignment is achieved, insert the distal screws as usual.
