Abstract

Our objective was to evaluate the safety and accuracy of a bedside technique for placing vena cava filters with intravascular ultrasonography. We conducted a prospective case series of 36 patients requiring prophylactic vena cava filter placement. Intravascular ultrasound (IVUS) was used to assess the best location for inferior vena cava filter placement. Location of best filter placement was compared with a bedside technique using a fluoroscopic examination. Thirty-six patients underwent an IVUS examination. The 21 men and 15 women had a mean age of 51 years. Our bedside placement technique was successfully performed in 34 patients. Two patients did not undergo a bedside technique because of inadequate imaging. The difference between best filter placement and bedside technique was 1.22 +/- 1.24 cm. In three patients our bedside technique differed from best filter placement by more than 3 cm. Excluding these three patients the difference between best filter placement and bedside technique was 0.92 +/- 0.79 cm. This bedside IVUS technique for placement of inferior vena cava filters is established as safe and accurate; however, knowledge of the limitations involving the technique is important.
