Fracture of Popliteal Artery Stents

抄録

In peripheral arterial obstructive disease, more than 50% of all lesions are localized in the femoropopliteal segment and surgical revascularization is the treatment of choice. Percutaneous transluminal angioplasty (PTA) is recommended for short lesions, with subsequent stent implantation if the result is sub-optimal or dissections occur after PTA or for restenosis. There are both acute and late complications with stent implantation. In the present patient, stents were placed in the left popliteal artery where the left knee joint flexes, and obstruction because of stent fracture occurred 6 months later. The patient eventually underwent left femoro-popliteal saphenous vein bypass grafting. (Circ J 2003; 67: 643 - 645)
