    A 45-year-old man with severe postthrombotic syndrome had IVC hypoplasia, bilateral iliocaval atresia, and extensive collateral veins.

  • 2

    A previously placed stent traversed an iliolumbar collateral rather than the native iliac vein.

  • 3

    IVUS-guided iliocaval reconstruction used sharp recanalization and overlapping stents, restoring brisk inline flow.

  • 4

    After reconstruction and staged superficial venous treatment, Villalta scores fell from 15 to 7, and imaging showed patent stents.

    Persistent dilated collaterals were associated with orthostatic hypotension, which the authors attributed to gravitational blood sequestration and reduced cardiac preload.
