Congenital Agenesia of the Inferior Vena Cava: A Diagnosis to Mention in Front of a Deep Vein Thrombosis

Congenital agenesia of the inferior vena cava (IVC) is an extremely rare morphological anomaly in the general population; found in approximately 0.0005% to 1% [1]. It is a rare cause of deep vein thrombosis (DVT) and could be responsible for less than 5% of thromboses without a contributory factor in subjects under 30 years of age [2].

We present a case of DVT agenesis, demonstrated by a CT angiography, performed as part of the etiologic assessment of extensive, bilateral and recurrent deep venous thrombosis (DVT), in a young 24-year-old man.

We discuss the mechanisms of occurrence of thrombosis associated with IVC agenesis and their possible clinical and therapeutic features.
