Acute limb ischemia may manifest by ischemic rest pain, ischemic ulcers, or gangrene. Acute arterial occlusion can be the result of emboli from a distant source, acute thrombosis of a previously patent artery, or direct trauma to an artery. Toe necrosis resulting from norepinephrine bitartrate (Levophed; Hospira Inc, Lake Forest, Illinois) is a rare case.
急性肢体缺血可能表现为缺血性休息痛、缺血性溃疡或坏疽。急性动脉闭塞可能是来自远处的栓子、先前通畅的动脉急性血栓形成或动脉直接创伤的结果。去甲肾上腺素酒石酸盐（Levophed；Hospira Inc，伊利诺伊州森林湖）导致的脚趾坏死是一种罕见情况。
