She returned 2 years later with debilitating short-distance right-calf claudication, and duplex and intraoperative angiography (Figure 1A and B) found distal SFA to above-knee popliteal artery 50%-70% restenosis, total of about 8 cm (Tosaka class II), and 50% restenosis of the below-knee popliteal artery. The below-knee popliteal stenosis received angioplasty with a 4x80 mm balloon, and the distal SFA to above-knee popliteal stenosis was treated with OCT-guided atherectomy (Figure 1C). Neointimal hyperplasia and atheroma material was removed (Figure 1D). The lesions received angioplasty with drug-eluting balloons (5x80 mm, LegFlow; Cardionovum, Bonn, Germany; Figure 1E).

She returned 3 years later with debilitating short-distance right-calf claudication again, and duplex and intraoperative angiography found mid-SFA to above-knee popliteal artery 50%-70% restenosis (Tosaka class II), total of about 8 cm, and 50% restenosis of the below-knee popliteal artery (Figure 2A and B). The above-knee popliteal stenosis had angioplasty with a 4x40 mm balloon (Chocolate PTA balloon catheter; Medtronic), and 5x60 mm drug-eluting balloon (In.Pact Admiral), and the mid-SFA was treated with OCT-guided atherectomy with good radiological results (Figure 2C). Neointimal hyperplasia and atheroma material was removed (Figure 2D). The lesions received angioplasty with a 5x80 mm drug-eluting balloon (In.Pact Admiral, Figure 2E).
