Peripheral arterial disease (PAD) is a global health problem. The risk factors for developing PAD have been clearly described in the literature, as have the medical therapies and preventative strategies for the prevention and treatment of PAD. Unfortunately, PAD patients remain undertreated with regard to guideline-directed medical therapy. During the last 2 decades, endovascular therapies for PAD have evolved such that randomized controlled trial level data are available for the treatment of lower extremity PAD at every major anatomic segment. Furthermore, endovascular therapy has evolved to the point that among experienced operators, an endovascular first strategy is reasonable for the treatment of most patients with intermittent claudication or critical limb ischemia.
