Ultrasonography is a well‐defined and widely accepted technique in the settings of interventional procedures requiring peripheral venous access, either for the confirmation of the vein patency (with the compression test) or for guiding needle insertion. This report describes a case of unsuccessful guidewire passage through the right iliac vein in spite of successful ultrasonography‐guided puncture of the femoral vein. On repeat duplex ultrasonography, the Doppler waveform showed a continuous pattern without respiratory phasicity, which was consistent with proximal venous occlusion. Venous Doppler signal waveform analysis can be helpful for ensuring downstream patency when planning long‐distance catheterization via femoral venous access.
