Anomalies of the IVC are uncommon but are important clinical entities to vascular surgeons, radiologists, urologists and oncologists. Duplication of IVC is a rare condition, uncommon anomaly with an incidence of 0.2-3%. Duplication of IVC or double IVC results from persistence of the left supracardinal vein. The size of both the vessels is variable and attempts have been made to classify such duplications as being of equal size or, left or right side dominant. In this video case report, we see the unusual occurrence of venous thromboembolism in association with a duplicated inferior vena cava.
