Abstract:
The revascularization of the lower limbs through a bypass graft from the descending thoracic aorta is one of the most uncommon surgical procedures within the scope of the so-called "extra-anatomic revascularization". It is an highly selective procedure in terms of indications and is regarded as an effective hemodynamic alternative, with acceptable long-lasting results. Two patients who underwent successfully the operation are reported, followed by a discussion on the technical aspects, indications, complications and early and late results of the procedure.
