Management of acute limb ischemia is complex and time sensitive, and delays in diagnosis and treatment may lead to irreversible tissue damage. Current data challenge the commonly accepted 6-hour ischemic threshold for acute limb ischemia, although variations in practice remain. Patients with chronic peripheral artery disease may tolerate longer ischemia time due to presence of collateral circulation. Here the authors discuss the presentation, workup, management, and postoperative care of patients with acute limb ischemia, with a focus on how management is altered depending on the duration and degree of ischemia.

UI	MeSH Term	Description	Entries
D007511	Ischemia	A hypoperfusion of the BLOOD through an organ or tissue caused by a PATHOLOGIC CONSTRICTION or obstruction of its BLOOD VESSELS, or an absence of BLOOD CIRCULATION.	Ischemias
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.	Retrospective Study,Studies, Retrospective,Study, Retrospective
D012307	Risk Factors	An aspect of personal behavior or lifestyle, environmental exposure, inborn or inherited characteristic, which, based on epidemiological evidence, is known to be associated with a health-related condition considered important to prevent.

D016896	Treatment Outcome	Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.

D058729	Peripheral Arterial Disease	Lack of perfusion in the EXTREMITIES resulting from atherosclerosis. It is characterized by INTERMITTENT CLAUDICATION, and an ANKLE BRACHIAL INDEX of 0.9 or less.

D023821	Limb Salvage	An alternative to AMPUTATION, SURGICAL in patients with neoplasms, ischemia, fractures, and other limb-threatening conditions. Generally, sophisticated surgical procedures such as vascular surgery and reconstruction are used to salvage diseased limbs.	Salvage, Limb
D035002	Lower Extremity	The region of the lower limb in animals, extending from the gluteal region to the FOOT, and including the BUTTOCKS; HIP; and LEG.	Extremity, Lower,Lower Limb,Membrum inferius,Extremities, Lower,Limb, Lower,Limbs, Lower,Lower Extremities,Lower Limbs
