<unk>  (ALI) occurs when there is a sudden lack of blood flow to a<unk> .<unk>  is caused by embolism or thrombosis, or rarely by dissection or trauma. Thrombosis is usually caused by peripheral vascular disease (atherosclerotic disease that leads to blood vessel blockage), while an embolism is usually of cardiac origin. In the United States, ALI is estimated to occur in 14 out of every 100,000 people per year. With proper surgical care,<unk>  is a highly treatable condition; however, delayed treatment (beyond 6 to 12 hours) can result in permanent disability, amputation, and/or death. In contrast to<unk> , chronic<unk>  threatening<unk>  results from peripheral artery disease that develops over time. While<unk> s in both<unk>  and chronic<unk> <unk>  may be pulseless, a chronically ischemic<unk>  is typically warm and pink due to a well-developed collateral artery network and does not need emergency intervention to avoid<unk>  loss. The New Latin term<unk>  as written, is a British version of the word<unk> , and stems from the Greek terms ischein 'to hold'; and haima 'blood'. In this sense,<unk>  refers to the inhibition of blood flow to/through the<unk> .
