Recurrent deep venous thrombosis in a patient with agenesis of inferior vena cava

Abstract

Background:Agenesis of the inferior vena cava (IVC) as a cause of recurrent deep vein thrombosis (DVT) is uncommon.Case:A 33-year-old male with no family history of thrombophilia, who had experienced multiple recurrent episodes of DVT over a 15-year period of unknown cause, was admitted into our hospital because of cellulitis in the right leg. Computer tomography with contrast of the abdomen showed an absence of IVC.Conclusion:Congenital absence of the IVC could be a rare risk factor for idiopathic DVT, especially in young individuals.
