Femoropopliteal artery disease accounts for a significant proportion of endovascular interventions (EVTs) for peripheral artery disease (PAD) in patients with disabling claudication or chronic limb ischemia. The femoropopliteal artery starts from the common femoral artery (CFA) to the superficial femoral artery (SFA) and ends at the popliteal artery. The SFA is the longest vessel, and it is hard to visualize the entire vessel in one image. However, it is the main target for endovascular works. Before EVT procedure, full evaluation by the angiography is needed. These include anatomical variation, lesion length, lesion characteristics, calcification, and stent restenosis pattern. Endovascular approach is based on these information. The benefit of revascularization is considered to correspond to the severity of ischemia. Their assessment led to optimal endovascular strategy for femoropopliteal occlusive disease. However, to keep the patency after procedure by current endovascular approach still remains unsolved.
