BENTO, Daniela; MACHADO, Rui; MENDES, Daniel  and  ALMEIDA, Rui de. Endovascular treatment of chronic venous occlusive disease - specifications of endoprostheses and comparison of results. Angiol Cir Vasc [online]. 2019, vol.15, n.2, pp.76-85. ISSN 1646-706X.

Introduction: Chronic occlusive venous disease manifests mainly at the level of the iliofemoral vein, and its treatment has been revolutionized by the emergence of endovascular techniques. Venous system stenting has evolved from the existing treatments of arterial occlusive disease. Some arterial stents were used in the venous system with good results, however, the need to improve the characteristics of these devices led to the development of stents dedicated exclusively to venous pathology. In recent years several dedicated endoprostheses have been approved, however, there are few studies comparing their characteristics and results. Tratamento endovascular da doença venosa crónica oclusiva - especificações das endoproteses e comparação de resultados Objectives: Update on the venous stents available and comparison of their characteristics and results. Methodology: The bibliographic research was performed in database "Natural Library of Medicine PubMed - Medline". Articles from the last 20 years with language in Portuguese and English were included. Greater relevance was given to research articles, but books and review articles relevant to the topic were also included Results/Discussion: There are currently 7 devices used in iliofemoral occlusive disease Wallstent" Endoprosthesis, Zilver® Vena ", Sinus-Venous®, Sinus Obliquus®, Vici® Venous Stent, Venovo® Venous Stent, Sinus Obliquus®and Abre" Venous. The short-term outcomes show high rates of technical success, primary and secondary patency, null mortality and low rates of periprocedural complications. Conclusion: Existing stents for venous use appear to be effective and safe in the treatment of iliofemoral occlusive venous disease. None of the devices stand out in terms of effectiveness, however, dedicated stents appear to have lower complication rates. Long-term studies are needed to confirm these results.
