[Endovascular treatment of aorto-iliac aneurysms. Made-to-measure endoprotheses increase the feasibility].

Abstract

The authors describe their experience of tailoring endoprostheses for endovascular treatment of aorto-iliac aneurysms with components available on the market. Between January 1996 and December 1999, 188 aorto-iliac aneurysms were treated by tailor-made endoprostheses using self-expanding Z stents made of stainless steel compiled with polyester ligatures and covered with standard commercially available polyester prostheses. These endoprostheses were implanted with an 18 to 24 Fr (usually 20 Fr) introducer and positioned by a surgical approach. This method allows construction of tubular, bifurcated, digressive or occlusive endoprostheses associated with an extra-anatomical bypass graft. It increased the number of endovascular procedures for aorto-iliac aneurysms in the authors' department. This number has been further increased by using endoprostheses with an uncovered proximal or distal stent for cases with particularly short or angled necks and by using hybrid endoprostheses with one or more extremities without a stent, allowing surgical suture of the anastomosis. The authors' results show that tailoring endoprostheses considerably increased the feasibility of endovascular treatment of aorto-iliac aneurysms, even in unselected patients whilst providing an effectiveness and safety to justify the continuation of this experience.
