However, when the occlusion cannot be successfully crossed, the RF wire technique has been shown to be a safe and effective option 3, 4, 5, 6. Central venography in multiple projections is essential at the beginning of the case to properly identify the correct CVO stumps, their diameters, and length of the occlusion and to plan the RF wire trajectory 3 .…”
