    Abstract:
    PURPOSE: This study was performed to evaluate the authors' experience with the endovascular treatment of abdominal aortic aneurysm (AAA) with use of a self-expanding nitinol stent covered with a polyester fabric device and to report the implant's technical features, the immediate results, and the outcome 30 days after device implantation. MATERIALS AND METHODS: From June 1997 to December 2001, we admitted 169 patients diagnosed with AAA. Of these, 134 were suitable to undergo endovascular repair with use of the Talent stent-graft. In one patient, it was technically impossible to proceed with the implantation procedure. Therefore, a total of 133 patients were treated with use of this technique (78.7%). The average age was 70.7 years (range, 52-88 y). There were 119 men and 14 women. Computed tomographic follow-up was done between the 15th and 30th postoperative days. RESULTS: The stent-grafts were successfully implanted in all 133 patients. Complications during the procedure included three type-I endoleaks (2.3%) and four iliac artery ruptures (3.0%), which were effectively treated by means of aortic or iliac extension grafts, respectively. The average surgical time was 2.92 hours (from 1.67 h to 7 h). Of the stent-grafts used, 125 were bifurcated (94.0%), two were straight tube grafts (1.5%), and six were conical aortouniiliac grafts (4.5%). Custom-made grafts were used in 62 patients (46.6%) and standard grafts were used in 71 (53.4%). Suprarenal fixation was performed in 117 patients (88%). One female patient developed a serious pulmonary embolism. Eight patients (6.0%) developed serious systemic inflammatory syndrome; two died of disseminated intravascular coagulopathy. There were two additional deaths, one from refractory shock and one suddenly from an unknown cause (total mortality rate, 3.0%). During the postoperative period, 70.3% of the patients developed mild fever (37.6 degrees C-38.9 degrees C). The average length of stay in the intensive care unit was 1.3 days (ranging from 1 d to 12 d) and the total hospitalization time was 4.2 days. Six type-II endoleaks were observed: two were corrected by video laparoscopy-assisted inferior mesenteric artery interruption and the other four were clinically followed up. CONCLUSIONS: The exclusion of AAA by endovascular techniques with use of the Talent device was possible in the majority of cases with a low incidence of complications. The most common serious postprocedural complication was systemic inflammatory syndrome.
