Background:
Many devices are available for endovascular aneurysm repair (EVAR). Our aim was to analyze morphological effects of the Zenith and Talent systems.
Methods:
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.
Results:
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.
Conclusion:
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.
