Endovascular reconstruction in inferior vena cava atresia in a patient with sickle cell trait

Atresia of the inferior vena cava (IVC) is a rare anomaly associated with increased risk of deep venous thrombosis and lower extremity venous stasis. A significant number of patients with caval atresia remain asymptomatic however, due to compensatory lower extremity collateral venous networks. Over time, these venous tributaries may become insufficient and lead to venous hypertension and subsequent ulcer formation. The following case report describes a 54-year-old male with sickle cell trait who presented with IVC atresia and successfully underwent a technically challenging endovascular reconstruction.
