Outcomes of Endovascular Therapy for Lower Limb Artery Diseases

Korean Vascular Intervention Society Multicenter Registry Study on Outcomes of Endovascular Therapy in Lower Limb Artery Diseases (K-VIS ELLA): (A Retrospective & Prospective Observational Study)

Yonsei University · NCT02748226

This study looks at how well endovascular treatments work for people with lower limb artery diseases, especially those with peripheral arterial disease, to see what helps improve their long-term outcomes.

What this trial studies

This multicenter observational study investigates the outcomes of endovascular treatments for patients with lower extremity artery diseases, specifically focusing on peripheral arterial disease (PAD). It includes both a retrospective cohort of patients treated from January 2006 until the IRB approval date and a prospective cohort of patients treated thereafter. The study evaluates clinical and lesion characteristics, procedural data, and long-term outcomes, including primary patency and revascularization rates. The goal is to identify risk factors associated with restenosis and target lesion revascularization.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20 years or older with symptomatic peripheral artery disease, including those with intermittent claudication or critical limb ischemia.

Not a fit: Patients who are pregnant, have severe cognitive impairments, or have a life expectancy of less than one year due to comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness of endovascular therapy for PAD, potentially improving treatment strategies and patient outcomes.

How similar studies have performed: Other studies have shown success with similar observational approaches in evaluating endovascular treatments for PAD, indicating that this methodology is well-established.
