Transplant renal arterial pseudostenosis is uncommon. It is a lesion in the iliac artery proximal to the implantation of the transplant renal artery.
Uncommon, although as the population of renal transplant recipients has become older and more diabetic, the incidence of this disease is rising.
It is most probably caused by a clamp injury to the recipient iliac artery during transplant or by high renin output from the transplanted kidney.
Usually normal kidney, On Doppler the waveform is “parvus et tardus” with a markedly delayed systolic upstroke. This finding is indicative of a significant stenosis proximal to the implanted artery.
Usually normal, although there is usually pressure gradient between the proximal and distal iliac artery.
Treatment and prognosis
This type of lesion may respond to angioplasty; however, if there is no response to angioplasty, it should be treated with a stent.
