Fig 1 An intravascular ultrasound image shows the vena cava at the lower edge of the origin of the renal veins with the right renal artery crossing posteriorly. This is the desired location to which the filter delivery sheath tip should be positioned for ideal filter placement.

Fig 2 An intravascular ultrasound image at the same level in the inferior vena cava as Fig 1 shows the decreased ultrasound penetration from the shadowing effect of the sheath and its radiopaque tip. This demonstrates that the sheath is in the desired position in the inferior vena cava for accurate delivery of the filter.
