Deep Venous Thrombosis and Agenesis of the Inferior Vena Cava: Typical Presentation Infrequent Anomaly

Abnormalities of the inferior vena cava (IVC) are rare. Its embryological development occurs between the sixth and eighth week of gestation, and depends on the persistence or regression of 3 pairs of veins: the posterior cardinal veins, the sub cardinal veins and the supra cardinal veins. The type of congenital alteration depends the moment that embryogenesis is altered. The most frequent clinical presentation is deep vein thrombosis, which occurs mainly in young men. Other clinical presentations are pelvic venous congestion and chronic venous insufficiency. The diagnosis requires a high diagnostic suspicion, and it is mainly through contrast-enhanced computed tomography of the abdomen and pelvis. The treatment will depend on the type of malformation and its presentation.
