From February 1998 and March 2000 fourteen patients underwent "custom made" aortic self-expanding endoprostheses implantation (World Medical Talent Sunrise): nine of them for dilative pathology of thoracic aorta and 5 for abdominal aortic aneurysm below renal arteries. The etiology was degenerative in 8 patients, false aneurysm in 2, chronic dissection in 2 cases, acute dissection in one patient and post traumatic in the last one. All patients underwent preoperative Computed Tomography and Substraction Angiography studies. Stent-graft implantation was successful in all cases but one who required the conversion of the endovascular procedure in traditional surgery for technical problems. There were no perioperative deaths or major complications. We registered 2 cases of dissection of the femoral artery used to introduce the stent-graft, and treated with an iliac-femoral prosthetic bypass. There were no cases of paraplegia or renal failure or bowel ischemia. With the exception of one patient, died for a car accident, the others are alive and continue their scheduled follow-up controls. Our experience shows that this procedure is safe, allowing favorable results, if compared to traditional surgery, even if it requires further long-term evaluations.
