[Vena cava inferior atresia as the cause of deep venous thrombosis].

The paper describes an 18-year-old woman with vena cava inferior atresia. She was hospitalised with deep venous thrombosis after she had taken contraceptives for two months and had been confined to bed for three weeks because of back pain. Anticoagulant treatment was successful. Vena cava inferior atresia is a rare condition, but it must be suspected in younger people with proximal bilateral deep vein thrombosis.
