＊20) When endovascular treatment performed for multiple regions, the case should be counted in each regions (If a case underwent endovascular treatment in both aorto-iliac and femoro-popliteal region, this case can be counted one in aorto-iliac, and one in femoro-popliteal region). ＊21) Counting the patients number not treated regions. When a case underwent endovascular treatment in multiple region, the case is counted as one case.
