Supplementary file 1_Comparison of aortoiliac disease stenting patency using balloon-expan

A 2012-2017 study from the Vascular Quality Initiative database compares primary patency rates for three stent types in peripheral arterial disease interventions. The analysis includes 1,886 patients with 2,673 lesions, reporting 1-year and 3-year patency outcomes. The dataset, authored by Ali A. Hasnie and shared under CC-BY-4.0, provides real-world evidence on stent performance.

Use Cases

• Compare long-term patency outcomes based on stent type (balloon-expandable, self-expanding, covered)
• Analyze patient demographic and periprocedural variables associated with stent success
• Model 1-year and 3-year primary patency rates using real-world clinical data
• Investigate the correlation between technical success rates and long-term outcomes in aortoiliac interventions

Strengths

• Includes 1,886 patients and 2,673 lesions, providing a substantial sample size for analysis
• Reports specific 1-year (98.4%, 97.1%, 96.3%) and 3-year primary patency rates for three stent types
• Uses an international database (Vascular Quality Initiative) spanning 2012 to 2017

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count for the underlying data is unknown, which may limit suitability assessment
• Data may reflect temporal bias inherent to the 2012-2017 collection period
