Study design: multicenter retrospective and prospective observational study
Study Cohort :
Baseline clinical and lesion characteristics, procedural and post-procedural data, clinical outcomes, hemodynamic, and imaging follow-up data are investigated. Primary patency and target lesion revascularization rates of the total cohort and patient subgroups are evaluated. Risk factors of restenosis and target lesion revascularization are determined.
This is an observational study. The study includes patients who underwent endovascular treatments for lower extremity artery diseases and investigates immediate and late outcomes of the treatments. The investigator does not assign any specific interventions.
