Stent-grafts in the superficial femoral artery

Superficial femoral artery disease is still cumbersome to treat. While percutaneous transluminal angioplasty (PTA) and stent replacement are well established treatment modalities for occlusive iliac or renal artery diseases, less favorable results are obtained with these techniques in the superficial femoral artery. Bypass surgery with the use of an autologous vein still gives the best results. A less invasive alternative is therefore desirable. The use of stent-grafts seems promising as it combines the technology of a less invasive endovascular treatment with the advantages of creating an anatomical endoprosthetic smooth conduit. This article gives an overview of the different types of stent-grafts and their clinical applications.
