ResumoTo report a long-term experience with the Talent Endoprosthesis for the treatment of abdominal aortic aneurysm (AAA).In the period between June 1997 and June 2003, 193 patients (171 men; mean age 71.0+/-7.8 years, range 52-89) with AAA were treated with a Talent Endoprosthesis. Patients were clinically and radiologically followed in the postoperative period, at 30 days, and then annually up to 72 months. In addition to computed tomographic scans, a plain abdominal radiogram was also performed annually for structural assessment of the stent-graft.Implantation success was 99.0% (191/193). Delivery system introduction was the cause of 1 failure, and the other patient was converted to surgery for intraprocedural device migration. There were 10 (5.2%) endoleaks (3 type I, 7 type II) at 30 days; all type I and 3/7 type II endoleaks were treated (93.3% secondary clinical success). Seven (3.7%) patients died in the perioperative period, including the conversion. During follow-up, 18 (9.3%) additional deaths occurred, and 4 new endoleaks (1 type I, 2 type II, 1 type III) were encountered. In up to 6 years' follow-up, the Talent Endoprosthesis did not present signs of material fatigue, but 1 component disconnection at 42 months led to death. There was no aneurysm rupture. After an initial increase in the aortic neck (1.2+/-1.1 mm) in the postoperative period, the neck diameters continued to increase until after the third year. An average reduction of 5.6+/-4.1 mm in the aneurysm diameter at 1 year was noted; the reduction gradually reached 14.1+/-10.7 mm after 60 months.The Talent Endoprosthesis was an efficient alternative for managing AAAs, achieving low morbidity and mortality rates and a good long-term clinical outcome in this study. The Talent Endoprosthesis did not present signs of material fatigue over a 6-year follow-up.
