Atresia of the Infrarenal Inferior Vena Cava in an Adolescent Presents with Bilateral Deep Vein Thrombosis

Tushar Menon, Ameera C Mistry, Shahin Bhagwagar, Rahul Malhotra

Atresia of the Inferior Vena Cava (IVCA) is a rare congenital vascular anomaly that can predispose patients to venous stasis and thrombotic events like Deep Vein Thrombosis (DVT). Young patients with IVCA may be asymptomatic until provoked by another risk factor, such as Oral Contraceptives (OCPs) use, hypercoaguable states, surgery, trauma, and immobilization. Here we present a young female patient with a history of OCPs and marijuana use, and no other relative risk factors, which presented with signs and symptoms of a DVT. Further investigation revealed previously undiagnosed IVCA. Typically, the relative risk for thrombotic events in healthy, young patients is low when using OCPs. In young, healthy patients with new or extensive thrombotic events that have few risk factors and no personal or family history of inherited thrombophilia’s, further investigation and careful testing and imaging should be prompted, as structural anomalies like IVCA may be present.
