Figure 2 Through a 4F dilator, a stiff 0.018-in. (0.0457-cm) wire was carefully pushed into the occluded vessel in millimeter increments followed by advancement of the dilator. The wire and dilator should follow the expected course of the IFVs in both AP and lateral projections. Contrast was hand-injected into the dilator after the wire was removed, demonstrating no extravasation. Note the length of the occluded segment, which extended from the left superficial femoral vein to the midportion of the IVC just below the renal veins (arrows).
