Abstract

Peripheral artery disease (PAD) is a common vascular condition affecting over 200 million people worldwide. It is primarily characterized by stenosis or occlusion of peripheral arteries due to atherosclerosis. The infrainguinal segment is frequently involved in PAD, making revascularization decisions for infrainguinal arterial disease (IAD) complex. Multiple factors, including the patient’s condition and anatomical characteristics, must be carefully considered when determining the optimal treatment approach. Once these factors are evaluated, the first revascularization strategy is selected from among open, endovascular, or hybrid modalities, based on high-level evidence. Endovascular therapy is widely accepted as the standard treatment for simple IAD, with balloon angioplasty and stenting being the commonly used techniques. However, advancements in endovascular techniques have enabled the treatment of increasingly complex lesions. Additionally, drug-based technologies have enhanced the durability of treatment outcomes, including improvements in primary patency rates and freedom from target lesion revascularization. Similar to surgical endarterectomy, percutaneous atherectomy has been developed to remove atherosclerotic plaques and mitigate intimal calcification. The purpose of this paper is to present an algorithm for revascularization of IAD through a comprehensive review of studies comparing the outcomes of various treatment modalities.
