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.
These 10 states make it more practical for physicians to participate in hospital ownership by aligning statutory structure, corporate practice of medicine rules, and population trends.
