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

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.
