Massive deep vein thrombosis after cesarean section treated with a temporary inferior vena cava filter: a case report

A 25-year-old woman suffered a massive deep vein thrombus in her left common iliac vein extending to the inferior vena cava after an abdominal cesarean section. The massive and floating inferior vena cava thrombus was considered to pose a high risk of pulmonary thromboembolism. After placement of a temporary inferior vena cava filter via the left brachial vein, thrombolytic therapy and anticoagulation therapy were instituted. The filter successfully prevented pulmonary thromboembolism during thrombolytic therapy. This patient was confined to bed because the filter moved vertically with left shoulder joint abduction. Although a temporary inferior vena cava filter is very useful for the prevention of pulmonary thromboembolism in a patient with deep vein thrombus, the appropriate range of activity for such a patient needs careful consideration.
