Acute limb ischemia is defined as a quickly developing or sudden decrease in limb perfusion, usually producing new or worsening symptoms or signs, and often threatening limb viability . Acute limb ischemia is overwhelmingly related to arterial occlusion, though extensive venous occlusion can lead to limb ischemia as well (ie, phlegmasia), but this is rare. The incidence of acute peripheral arterial occlusion causing acute limb ischemia is approximately 1.5 cases per 10,000 persons per year .
