Greenfield filters for prevention of pulmonary emboli may be placed in the inferior vena cava by surgical cutdown or by percutaneous insertion through the femoral or jugular veins. We evaluated the use of the percutaneous techniques 52 times in 50 patients.

In the unsuccessful case, placement was attempted via the left femoral vein; the carrier could not be advanced from the common iliac vein to the inferior vena cava. This patient required surgical occlusion of the cava. There was one major complication, a hematoma in the right side of the groin that required transfusion. This occurred in ...
