“What IVC?”: Deep Vein Thrombosis in the Context of IVC Dysgenesis

Among young, otherwise healthy adults with unprovoked deep vein thrombosis (DVT), uncommon causes like variation in the normal sequential development of inferior vena cava (IVC), must be explored. Anomalous IVC conditions are estimated to occur up 9% general population, rarest anomaly being agenesis at 0.0005% - 1% population prevalence. DVTs more likely develop this due venous stasis from decreased return, even formation extensive collateral veins. Herein, authorial team presents a 22-year-old patient leg pain and swelling who was found have acute DVT, and, incidentally, absence suprarenal robust system on further imaging studies. The morbidity is very high, attention should given young patients present new-onset DVT setting coagulation studies lack personal or family history clotting disorders, as need for specialized such venograms necessary secure proper diagnosis.
