Abstract:

Femoro ⁃popliteal artery（FPA） calcification is a common disease in vascular surgery. Its incidence and diagnostic rate are increasing year by year，and it has become an important disease that endangers the mobility and life health of patients. Due to the special anatomical structure and complex mechanical characteristics of FPA，the lesions are often manifested as long segment，diffuse and severe calcification occlusion of the tube wall，which is often difficult to deal with，and the rate of postoperative reintervention is high. The severity of wall calcification is an important factor affecting the therapeutic effect. In recent years，new ideas and technologies for endovascular treatment of FPA calcification have emerged in an endless stream，which have deeply influenced the selection of clinical treatment strategies and will also determine the development direction of endovascular treatment for a long time to come. This article would briefly state some new treatment concepts on the FPA calcified lesions such as“leave nothing behind”or“vessel preparation”，“classification of dissection after balloon dilation and the new dealing strategies”，and emphatically summarized some commonly clinical used new technologies such as the emergence of some new guide wires and stents，new technology for volume reduction in cavity，special balloons，“composite”technology and“Pave⁃and⁃Crack”technology. In order to provide some references for the selection of equipment and future research ideas，and further improve the success rate of endovascular opening and postoperative patency rate of FPA with severe calcification lesions.
