    Abstract:
    BACKGROUND: Although endovascular aneurysm repair has been shown to be an effective way to treat abdominal aortic aneurysm (AAA), certain anatomic characteristics such as a short aortic neck, limit its applicability. Initially, commercially available devices were approved only for the treatment of AAA with an aortic neck length ≥ 15 mm. The purpose of this study was to evaluate the outcomes of the recently approved Talent endograft for AAAs with a short aortic neck length (10-15 mm). METHOD: Data were obtained from the prospective, nonrandomized, multicenter Talent enhanced Low Profile Stent Graft System trial which enrolled patients between February 2002 and April 2003. A total of 154 patients with adequate preoperative imaging were identified for this study. Subgroup analyses were performed for AAA with 10-15 mm aortic neck and those with >15 mm neck. Safety and effectiveness endpoints were evaluated at 30 days, 1 year, and 5 years postprocedure. RESULTS: Patients treated with aortic neck lengths of 10-15 mm (n = 35) and those with >15 mm (n = 102) had similar age, gender, and risk factor profile. Both groups had similar preoperative aneurysm morphology in terms of maximum aneurysm size, degree of neck angulation, or proximal neck diameter. There were no statistically significant differences in freedom from major adverse events and mortality rates at 30 and 365 days. Similarly, there was no difference in the effectiveness endpoints at 12 months. At 5 years, there was no difference in migration rate, endoleaks, or change in aneurysm diameter from baseline. In addition, there is no difference in freedom from aneurysm-related mortality (94% vs. 99%). CONCLUSIONS: AAAs with short aortic necks (10-15 mm) and otherwise suitable anatomy for endovascular repair can be safely and effectively treated with the Talent endograft with excellent 1 and 5 year outcomes.
