Percutaneous Transluminal Angioplasty of Infrapopliteal Arteries in Patients with Intermittent Claudication:Acute and Six-Month-Results

Özet

Introduction: Critical leg ischemia represents the final stage of atherosclerotic peripheral arterial disease (PAD). Patients affected by critical leg ischemia are the most complex subset of PAD and typically have chronic pathological consequences of hypertension, hyperlipidemia, diabetes and renal failure.Methods: In this study, we evaluated the early and sixth-month outcomes of percutaneous transluminal angioplasty (PTA) in patients with stenosis or occlusion at the infrapopliteal level. Only one leg was treated in one session. None of the patients received infrapopliteal stents, and only balloon angioplasty was performed.Results: In our study, 41 vessels with a total of 48 lesions in 31 patients were treated. The primary patency rate of the vascular segments treated at follow-up was 72.9%.Discussion and Conclusion: In PTA, failure in the procedure and loss of patency are the main therapeutic challenges to be solved. Large-scale, multicenter, prospective studies that systematically evaluate existing infrapopliteal treatment methods are needed to develop contemporary, proven treatment standards.
