Arteriosclerosis obliterans (ASO) is a peripheral vascular disease caused by atherosclerotic luminal stenosis or occlusion, leading to ischemia and hypoxia of distal lower extremity tissues., seriously affect the patient’s quality of life, and may even lead to amputation and other serious adverse outcomes. Surgical treatment is the main approach for ASO, aiming to restore blood circulation in the lower extremities. However, postoperative insufficient lower extremity perfusion remains a common complication. If not identified and intervened in time, it is prone to progress to severe conditions such as acute ischemia and limb necrosis. This article systematically reviews the related risk factors of insufficient lower extremity perfusion after ASO, summarizes the core indicators and methods for early identification, generalizes the current mainstream nursing intervention strategies, analyzes the deficiencies of existing research, and looks forward to future research directions, with the aim of providing references for clinical nursing practice and improving the postoperative prognosis of patients.
