CASE 29: Transplant Renal Artery Stent Protruding Into the Iliac Artery

John S Pellerito; Ernesto P Molmenti

FIGURE 112-109

Renal artery stenosis that was treated with placement of a stent. Note that the stent protrudes into the iliac artery (arrow), raising concerns as to whether it may impede flow in the iliac artery.

FIGURE 112-111

Duplex Doppler ultrasound evaluation of the iliac artery proximal to the site of the stent protrusion (anastomosis of the renal artery to the iliac artery) shows adequate flow.

A radiograph of the iliac artery highlights the site of anastomosis. The radiograph shows waveforms that indicate normal flow.

Flow distal to the stent is also adequate. There were no long term complications. No further action was necessary.
