Korean Vascular Intervention Society Study on Outcomes of Endovascular Therapy for Symptomatic Lower Limb Artery Disease Retrospective and Prospective Observational Study

What this Trial Is About

Researchers are studying patients with lower extremity artery disease who have undergone or will undergo endovascular treatments. This observational study includes both retrospective and prospective groups to investigate the immediate and long-term results of these treatments. The study aims to understand treatment outcomes such as vessel patency and the need for repeat procedures, as well as risk factors for restenosis and target lesion revascularization. The study consists of two cohorts a retrospective cohort enrolling patients treated from January 2006 until IRB approval, and a prospective cohort enrolling patients treated from IRB approval until July 2018. No new treatments are assigned by the researchers, as this study observes standard endovascular treatments. Data on clinical characteristics, procedural details, imaging, and follow-up outcomes are collected for all participants. Participants are monitored through clinical and imaging evaluations to assess vessel patency and the occurrence of target lesion revascularization at 12 months. Researchers collect baseline and follow-up information including hemodynamic measurements and clinical outcomes. The total study duration includes retrospective data review and prospective follow-up of patients undergoing treatment, with ongoing assessment of risk factors and treatment effectiveness.
