Many devices are available for endovascular aneurysm repair (EVAR). Our aim was to analyze morphological effects of the Zenith and Talent systems. Patients included underwent EVAR from June 1999 to June 2005 using a Zenith or Talent stent-graft, with computed tomography follow-up. Aortic dimensions over time and clinical outcome were analyzed. Twenty-nine patients with Zenith stent-grafts and 33 with Talent devices were included. Mean preoperative age was similar (75.5+/-6.0 years vs 74.2+/-6.7 years; P=.29). Preoperative neck length was longer in the Zenith group (29.9+/-15.2 mm vs 25.5 +/- 10.8 mm; P=.10), and stent-graft oversizing was greater in the Talent patients (20.2%+/-7.9% vs 23.0% +/- 11.3%). There was proximal aortic dilatation and aneurysm sac shrinkage in each group. Complication rates were comparable, with 83% of both groups free from 10-mm migration. Although device designs differ, there is no difference in clinical outcome between Zenith and Talent stent-grafts. Migration rates were not influenced by suprarenal fixation.
