The development of the inferior vena cava (IVC) involves three paired embryonic veins and takes place during weeks 6–10 of gestation. The posterior cardinal veins are the first to develop posteriorly and mostly regress, except for their distal aspect, which leads to the formation of the iliac bifurcation (Ureyen et al. 2013). The suprarenal IVC forms from an anastomosis between the right subcardinal and vitelline veins (Berman and Minocha 2020). Next, the subcardinal veins develop anteromedially to the posterior cardinal veins. The right subcardinal vein persists to the right of the IVC throughout normal development, whereas the left subcardinal vein completely regresses (Ureyen et al. 2013). The subcardinal veins are responsible for forming most of the infrarenal IVC (Berman and Minocha 2020). Finally, the paired supracardinal veins form dorsally to the subcardinal veins. As with the subcardinal veins, the left supracardinal vein regresses while the right persists and eventually forms the infrarenal portion of the IVC (Ureyen et al. 2013).
