Article Figures & Data

Figures

  • Figure 1.
    Figure 1.

    Ultrasound of the right kidney shows turbulent flow in the lower pole with abnormal waveforms, consistent with a renal arteriovenous fistula. Although resistive indices were not measured, they were subjectively low, further corroborating the presence of a renal arteriovenous fistula.

  • Figure 2.
    Figure 2.

    Computed tomography angiography shows early filling of the right renal vein in the lower pole (arrows), corresponding to the renal arteriovenous fistula.

  • Figure 3.
    Figure 3.

    (A) Right renal angiogram shows abnormal vasculature of the lower pole with early opacification of the lower pole renal vein (arrows). (B) Selection of the tertiary branch of the inferior branch of the right renal artery shows similar findings of an abnormal tangle of vessels and filling of the renal vein (arrows). (C) Postprocedure coil embolization of the small feeding artery shows no further identification of the renal arteriovenous fistula.

  • Figure 4.
    Figure 4.

    Postintervention ultrasound shows normal waveforms and resistive indices, without evidence of the previously seen turbulent abnormal flow. Echogenic material is noted in the treated renal arteriovenous fistula region, corresponding to the metallic coils used during embolization.
