A 74 year old patient with a history of PCKD and kidney transplantation 15 years prior, presented with progressive kidney failure. The ultrasound showed normal size,echogenicity as well as RI values. There was a light delay in the systolic acceleration pattern of the Doppler signal in the proximal kidney arteries. Through angiographic assessment, a severe stenosis was found in the proximal iliac artery, which was treated by stenting. The patient’s Creatinine values improved after the intervention.
Even slight changes in the ultrasound Doppler pattern should raise the suspicion for hemodynamically significant changes in supplying arteries and necessitate further multidisciplinary investigation.
