Penetrated inferior vena cava filter retrieved by open surgery with deep hypothermic circulatory arrest.

BACKGROUND AND AIM Complications of inferior vena cava filters are relatively common, and they vary according to different filter types and designs. We aim to present a case of penetrated inferior vena cava filter into the liver. METHODS Case report. RESULTS A 42-year old man with thrombophilia (prothrombin gene mutation) required the insertion of an inferior vena cava filter because of recurrent gastrointestinal bleeding associated with oral anticoagulation. However, it penetrated through the retro-hepatic vena cava into the liver, being manifested by constant, blunt abdominal pain. Endovascular retrieval was considered of extreme risk, though a surgical approach was performed under cardiopulmonary bypass with deep hypothermic circulatory arrest. The patient has recovered uneventfully with complete symptom relief. CONCLUSIONS In symptomatic penetrated vena cava filters in which endovascular retrieval is not feasible, a surgical approach with appropriate planning is a safe and effective treatment.
