A Common Manifestation With an Uncommon Diagnosis: Intractable Deep Vein Thrombosis due to IVC Agenesis in a Young Woman

Abstract

Inferior vena cava agenesis (IVCA) is a rare entitiy wherein many patients remain clinically silent and are found incidentally on radiological imaging studiesas a result of the compensatory enlargements of many collateral veins to maintain venous return. However, IVCA may also be diagnosed following serious acute complications, particularly unprovoked proximal iliofemoral deep vein thromboses (DVT) in young individuals. Herein, we report a 25-year old postpartum female patient presented with acute swelling on the right lower extremity and diagnosed with IVCA following acute occlusive iliofemoral DVTs.We aimed to emphasize the importance of radiological evaluation and management of these patients with some considerations out of routine practice.
