Percutaneous retrieval of Kimray-Greenfield filter from right atrium and placement in inferior vena cava.

Inadvertent placement of a Kimray-Greenfield filter into the right side of the heart occurred in the operating room. With the use of intraoperative fluoroscopy while the patient remained under general anesthesia, the filter was extracted and successfully placed in the inferior vena cava. This was accomplished with standard percutaneous catheter techniques from the femoral route.
