Abstract

There is a growing need for dedicated endovascular devices to treat pathologies affecting the venous system. However, because of a lack of research into venous diseases and treatments, the optimal design, material, and mechanical properties of venous stents remain unknown. Development of the ideal venous stent should be based on a thorough understanding of the underlying venous pathology. There are multiple venous diseases that differ from each other depending on their location (iliocaval, superior vena cava), mechanism (thrombotic versus nonthrombotic lesions), and chronicity. Thus, it is likely that stent material, design, and features should differ according to each underlying disease. From a mechanical point of view, the success of a venous stent hinges on its ability to resist crushing (which requires high global and local radial rigidity) and to match with the compliant implant environment (which requires high flexibility). Device oversizing, textile coverage, and drug coating are additional features that should be considered in the context of venous diseases rather than directly translated from the arterial world. This review examines the unique forces affecting venous stents, the problems with using arterial devices to treat venous pathologies, preliminary results of a study comparing crush resistance of commercially available laser-cut stents with a novel braided stent design, and its applicability to venous interventions.
