Development in endovascular surgery made it possible to treat thoracic and abdominal aortic aneurysms by using catheter techniques. In 1990, Parodi performed the first unilateral stent-graft implantation, thereafter a rapid progress commenced in this field. Since middle nineties, bifurcated stent-grafts have been brought into general use. In Hungary, stent-graft implantations have been performed in certain centers since 1999. The authors demonstrate a case operated on at the Department of Vascular Surgery, University of Pecs for aneurysm of thoracic aorta with involvement of the origin of left subclavian and carotid arteries. In order to maintain the flow in left carotid artery, right to left carotico-carotid interposition was shaped, then stent-graft implantation was carried out for the thoracic aneurysm. Preoperative investigations, surgical technique and postoperative follow up are discussed in this case report.
