SVS 2019: Future venous stents should fuse greater flexibility with radial force

1175


Rabih Chaer (Pittsburgh, USA) talks to Venous News at the Society for Vascular Surgery’s Vascular Annual Meeting (SVS VAM; 12–15 June 2019, Washington, DC, USA)about the “need for dedicated venous stents” in the US in anticipation of the recently US FDA approved stents becoming more widely available.

Venous disease needs “different stents based on different pathologies, including better radial force and more flexibility in other areas”, something that Chaer hopes that the new devices might deliver.

These new stents “may improve on some of the deficiencies of existing technologies” but veins may behave differently at the level of the vena cava and the common iliac vein when compared to the external iliac vein or the common femoral vein, and in these latter locations a combination of greater flexibility and radial force are needed.

Chaer adds that he would also like to see longer term follow-up to see what the rate of fracture is because this is a “concern” and also a wider range of diameter and length to allow for the treatment of “different segments of the venous anatomy”.
