Abstract
The patient was 50s woman who was treated with norgestrel drug for bleeding from the uterus due to adenomyosis. She complicated with deep vein thrombosis and thromboembolism of the pulmonary artery. After a retrievable inferior vena cava (IVC) filter (Cordis OptEaseTM) was implanted, she was performed hysterectomy. Because the thrombus had disappeared due to anticoagulant therapy with warfarin, we attempted to retrieve of the IVC filter via femoral vein. However, during the procedure, the IVC filter was markedly deformed and it became impossible to retrieve transvenously. A computed tomographic scan revealed that the strut of the IVC filer markedly oppressed the duodenum from the back side. However the patient complained no abdominal pain and had no gastrointestinal bleeding, we were afraid of the duodenal perforation in the future. After the discussion about the indication of the operation, we performed surgically removal of the IVC filter to prevent the duodenal perforation 39 days after implant of the IVC filter. The post-operative course was uneventful.
