What is the incidence of inferior vena cava (IVC) duplication?
The incidence of inferior vena cava duplication is reported to be ~1.5\% (range 0.2-3\%) 3. Case reports of association with ureteropelvic junction anomaly and retrocaval ureters have been described 5.
Which side of the IVC drains into the left renal vein?
Since the IVC is not a midline structure, there is asymmetric drainage of the vein. Notably, the gonadal and suprarenal veins drain directly into the IVC on the right side. However, on the left side, they first drain into the left renal vein, which subsequently empties into the IVC.
What is the difference between duplicated and transposition of the IVC?
The renal vein is an important landmark for this differential. IVC continues on both sides of the aorta, in duplicated IVC. However, in transposition of the IVC, it continues on the left side of the aorta only.
