Acute Limb Ischemia An Emergency Medicine Approach

Acute limb ischemia is a medical emergency with significant morbidity and mortality. Rapid diagnosis is required because it is a time-sensitive condition. Timely treatment is necessary to restore blood flow to the extremity and prevent complications. The differential diagnosis of acute limb ischemia is broad. Classification of severity of acute limb ischemia is based on clinical variables. A suspicion of acute ischemia based on history and physical examination warrants heparin administration and vascular surgery consultation. The decision for endovascular thrombolysis or standard surgery depends on etiology, duration, and location of vascular occlusion. This article evaluates the diagnostic approach and management for acute limb ischemia.
