Acute Bilateral Renal Vein Thrombosis Qi Qian, MD, Nathan A. Saucier, MD, Bernard F. King, MD  American Journal of Kidney Diseases  Volume 54, Issue 5, Pages 975-978 (November 2009) DOI: 10.1053/j.ajkd.2009.06.035 Copyright © 2009 National Kidney Foundation, Inc. Terms and Conditions

Figure 1 (A) Coronal reconstructed image from the patient's computed tomographic (CT) urogram shows bilateral renal vein thrombosis (RVT) extending into the inferior vena cava with a delay in venous washout and opacification of the collecting system in both kidneys. (B) Repeated CT scan of the patient after 3 months of anticoagulation therapy shows resolution of RVT. A Gunther-Tulip filter is notable in the suprarenal inferior vena cava.

Figure 2 (A) Longitudinal ultrasound image of the patient's right kidney (delineated by*) shows increased echogenicity in the cortex caused by renal vein thrombosis. (B) Transverse image of the left kidney (delineated by*). Note the Doppler gate (red arrow) was centered in the left renal artery with the Doppler waveform showing forward flow during systole (white arrows) and reverse flow during diastole (white arrow heads). (C) Arterial waveform of the right renal artery from a healthy individual shows a normal pattern of arterial peak systolic velocity (arrows) followed by a low-resistance diastolic velocity (arrowheads) with forward flow throughout systole and diastole.
