Cadaveric Identification of a Left-Sided Inferior Vena Cava and Its Embryologic Basis
Manini Majithia et al.
The inferior vena cava (IVC) is the largest vein in the body and typically forms from the union of the common iliac veins, ascending along the right side of the vertebral column to return deoxygenated blood to the right atrium. Although variations in IVC anatomy are uncommon, they hold important clinical relevance for surgical procedures, radiologic interpretation, and vascular interventions. One such variation is a left-sided inferior vena cava (L-IVC), a rare anomaly reported in approximately
