1 Calcified in-stent restenosis in a venous stent

2 Fig 1 Computed tomography scans showing compression of the stent at the May-Thurner point (a) and high-density (calcified) material inside the stent distal to the compression (b). Three-dimensional reconstructions of these scans show the entire stent, including the compressed outflow and the calcified material within it as well as the vena cava filter (c and d).

3 Fig 2 Digital subtraction phlebography showing the results after 48 hours of ultrasound-accelerated catheter-directed thrombolysis (UACDT, a) and after mechanical debulking with the Rotarex catheter (b).

4 Fig 3 Digital subtraction phlebography in the anteroposterior projection (a) and at the same angle of view as the three-dimensional reconstruction in Fig 1, c (b) showing the re-established venous outflow through the left iliac veins. The new stent is fully expanded and covers the entire length of the old stent, including the May-Thurner point. The residual calcified material is sandwiched between the two stents on the inferior right-hand side.
