[Consideration on the treatment of chronic occlusive lesions of the iliac arteries].

This study addresses the problem of the best treatment for chronic unilateral obstructive lesions of the aorto-iliac arterial axis. After making a review of the literature, some considerations are made. In recent years this disease has increasingly been treated by endovascular methods with dilation (angioplasty) and stents. However, the classic indications (short stenotic obstruction), supported by national and international guidelines, are being continually widened by operators acquiring growing skills with this method. Nevertheless, no long term studies have demonstrated a clear superiority, in severe cases, of endovascular methods over traditional surgical methods (by-pass), as regards either long term results or costs. Among the traditional methods, many surgeons prefer the femoro-femoral by-pass to the orthopic aorto-femoral by-pass, particularly because of its lesser invasiveness. However, it should be noted that comparisons of the two methods have yielded results in favour of the orthotopic procedure, above all about long term results.
