  • Figure 1
    Doppler sonography in the first day after renal allograft transplantation

    A poorly perfused kidney graft is shown. The renal artery exhibits a tardus parvus waveform (slow systolic upstroke, rounded and diminished peak systolic velocity, and low resistivity index), indicating severe...

     
    Area of Interest: Kidney; Imaging Technique: Ultrasound-Spectral Doppler; Procedure: Diagnostic procedure; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 2
    Angiography of the iliac sector in the first posttransplantation day

    Stenosis of the external iliac artery at the vascular anastomosis site (arrows) is documented. (Ao–abdominal aorta artery; CIA-left common iliac artery; RA–renal allograft artery; EIA-left external iliac artery;...

     
    Area of Interest: Interventional vascular; Imaging Technique: Catheter arteriography; Procedure: Diagnostic procedure; Special Focus: Dissection;
     
     
  • Figure 3
    Doppler sonography in the first day after vascular surgical revision

    An intrarenal waveform spectrum with brisk systolic upstroke, low end-diastolic flow, and a high resistivity index is demonstrated. These Doppler findings are compatible with acute tubular necrosis.

A poorly perfused kidney graft is shown. The renal artery exhibits a tardus parvus waveform (slow systolic upstroke, rounded and diminished peak systolic velocity, and low resistivity index), indicating severe proximal arterial obstruction.
 
Stenosis of the external iliac artery at the vascular anastomosis site (arrows) is documented. (Ao–abdominal aorta artery; CIA-left common iliac artery; RA–renal allograft artery; EIA-left external iliac artery; IIA-left internal iliac artery)
 
An intrarenal waveform spectrum with brisk systolic upstroke, low end-diastolic flow, and a high resistivity index is demonstrated. These Doppler findings are compatible with acute tubular necrosis.
