To investigate patency rates of balloon-expandable, self-expanding, and covered stents in patients with aortoiliac artery disease using a large international database, focusing on real-world data.
Key Findings:
58% of stents implanted were balloon-expandable stents.
No significant difference in 3-year primary patency rates among stent types (P = 0.17).
Overall technical success rate was excellent in all three stent groups (>99%).
Interpretation:
Stent selection for aortoiliac PAD interventions should prioritize cost, lesion characteristics, operator judgment, and other relevant factors rather than relying solely on long-term patency outcomes.
Limitations:
Retrospective design may introduce selection bias.
Exclusion of patients with prior interventions may limit generalizability; specific types of prior interventions excluded should be noted.
Conclusion:
Contemporary data indicate no meaningful correlation between stent type and 3-year primary patency in aortoiliac PAD interventions.
