The vasculogenic erectile impotence, caused by occlusion and/or stenosis of arteries supplying the penis, is the most common cause of erectile failure in men over 40 years. The vasculogenic impotence is more found by peripheral vasculopathies like diabetes mellitus and nicotine abuse. It is important that the precise site of vascular lesion is established with selective arteriography of the hypogastric- internal pudendal axis. The specific aim of surgery is to increase the cavernosal arterial perfusion pressure and blood inflow in patients with vasculogenic erectile dysfunction secondary to pure arterial insufficiency. There have been multiple revascularization techniques described for the treatment of proximal or distal occlusion with variable results. Microsurgery is important for distal lesions and we think that the best candidates for the Michal II procedure seem to be those with localized obstruction of the internal pudendal, while venous arterialization is the preferred procedure for patients with pathological cavernous or dorsal penile arteries. In this paper the most important procedures to restore physiological erection are presented; however no single revascularization procedure has been generally accepted as a definitive answer to this problem. There is a need for further prospective studies with longer follow-up and more objective investigations.
