Prevention of Possible Toxic Effects on the Kidney Graft with Parvus Tardus Waveform

The aim of this study was to present a patient (acute allograft dysfunction after a kidney transplantation) with previously detected minimum plaque on both iliac arteries by scintigram and afterward a pathological color doppler ultrasound (cdu) record and to point on possibility of avoiding toxic computed tomography (ct) angiography in certain renal graft recipients. ultrasound (us) findings showed normal graft size, whereas doppler signals detected parvus‑tardus waveforms pointing to arterial stenosis. isotope perfusion scintigraphy registered a slow flow on both iliac arteries and normal graft perfusion. ct angiography has not been performed because of the possible toxic effects to the graft. we believe that favorable clinical and biochemical findings along with us and isotope ratio monitoring are sufficient to avoid ct contrast angiography.
