Surgical Rodent Models for the Study of Peripheral Arterial Disease

Cardiovascular disease remains the leading cause of morbidity and mortality worldwide, with atherosclerosis and maladaptive vascular remodeling serving as central drivers of clinical events. Mechanistic investigation of arterial disease processes relies heavily on experimental animal models that permit precise control of vascular injury, hemodynamic forces, and ischemic stress. Over the past several decades, murine and rat models have become indispensable tools for studying endothelial dysfunction, intimal hyperplasia, flow-mediated remodeling, and ischemia-reperfusion injury. Each model reproduces distinct aspects of human vascular pathology while offering unique technical and biological advantages. This review summarizes commonly used murine and rat models of arterial disease, emphasizing the biological mechanisms they study, the surgical techniques used, pathophysiology, experimental endpoints, advantages, and limitations.
