Is vessel prep necessary before treating the superficial femoral artery?

The standard of care for treating symptomatic peripheral arterial disease has been percutaneous transluminal angioplasty with or without stenting over the last couple of years. This endovascular treatment of claudicants or patients with critical limb ischemia has increased in numbers and has even surpassed open surgery. Our daily practice has evolved to an endovascular-first approach, especially in the femoropopliteal region, being the most frequently treated vessel. However, neointimal hyperplasia and elastic recoil leading to target lesion restenosis or occlusion after initial successful treatment is not uncommon. In recent years, drug-eluting technologies on balloons or stents have been investigated as a potential solution for this problem with excellent results compared to plain-old balloon angioplasty. Nonetheless in the majority of those trials, the bailout stenting rate increased with lesion complexity, albeit it in long or heavily calcified lesions due to flow-limiting dissections, elastic recoil or the calcium barrier preventing adequate drug uptake. There is a need for vessel preparation in order to ameliorate drug delivery, especially in complex lesions. Multiple devices are available to prepare even the most challenging lesions for drug uptake or stenting, by achieving maximal luminal gain and by minimizing dissections. This review aims to give an overview of the most common modalities for vessel preparation in the superficial femoral artery beside plain old balloon angioplasty together with an overview of the current literature of each device in the superficial femoral artery.
