Summary:

Description
  • Radiopaedia case ID: 21159
  • Image ID: 2811122
  • Plane projection: Transverse
  • Modality: Ultrasound
  • System: Vascular
  • Findings: The proximal left renal vein (LRV) is grossly distended. There is an 8-fold decrease in the diameter of the LRV as it passes between the superior mesenteric and aorta. Aliasing is seen on color Doppler ultrasound within the stenosed area of the left renal vein. Grossly elevated peak systolic velocities (PSV) were seen within the left renal vein stenosis. There was a 12-fold increase in PSV compared to the proximal segment. Antegrade flow was demonstrated in the proximal left renal vein. The longitudinal image shows a sharp take-off of the superior mesenteric artery and suggests a 16-fold decrease in diameter of the left renal vein.
