Minimal invasive treatment (called "endovascular") of the arteries of the lower limb remains problematic, because recurrent disease ("restenosis") frequently leads to recurrent symptoms. As yet, balloon angioplasty remains the recommended strategy to revascularize the superficial femoral artery (artery of the thigh). We investigated whether the use of a vascular endoprosthesis ("stent") improves patients´ outcome.
