[Advanced interventional techniques and therapies in the treatment of peripheral artery disease below the knee]

Abstract

In patients with peripheral artery disease, the options for interventional therapy of critical limb ischemia have increased within the last few years. Different antegrade and retrograde techniques for vascular recanalization are used to pass even complex and long stenoses or occlusions below the knee (BTK). A variety of diverse wires, catheters and stent types allows arterial recanalization of the lower leg and increases the impact of therapeutic efforts. This review article describes indications, advanced techniques as well as materials in BTK interventions and summarizes current evidence-based study results.
