[Revascularization of the 2 lower limbs from the descending thoracic aorta without laparotomy]

Arterial bypass of the lower limbs from the thoracic aorta approached through a thoracic or abdominal route has already been described. The technique reported here is original in that the descending thoracic aorta is exposed through thoracotomy, and the prosthesis is passed behind the left kidney, then, for the right leg bifurcation, through Retzius' space without laparotomy. Two patients were operated upon with this technique which is described in detail, together with its potential indications, advantages and disadvantages.
