(A) CT scan demonstrating dilated left renal vein compressed between the superior mesenteric artery and aorta with an arrow pointing to the area of compression. (B) A sagittal CT scan demonstrating an aortomesenteric angle of 18.56 . (C) A sagittal CT scan demonstrating an aortomesenteric distance of 5.45 mm.

A CT venogram demonstrated compression of the LRV between the superior mesenteric artery and the aorta with a prominent left ovarian vein (LOV) as seen in Figure 1.
(A) Phlebography demonstrating stenosis of the LRV with reflux into the LOV. (B) Venogram after stent deployment. Reflux into the left ovarian vein is no longer seen. The distal part of the stent is somewhat constrained, but the proximal part prolapses into the IVC. (C) Follow-up duplex ultrasound at 3 months. (D) Post-procedure LRV duplex velocities and assessment of velocity ratio. IVC, inferior vena cava; LRV, left renal vein; LOV, left ovarian vein.

The LRV was cannulated, and angiograms were performed, demonstrating the venous dilatation and reflux into an engorged left ovarian vein (Figure 2). Checking angiograms (Figure 2A) showed resolution of the stenosis and the absence of reflux into the ovarian vein. She was symptom-free at 3-month follow-up with a duplex ultrasound demonstrating resolution of stenosis (Figure 2C).
