Limb Ischemia

Acute limb ischaemia (ALI) occurs when there's a sudden lack of blood flow to a limb. Acute limb ischaemia is caused by embolism or thrombosis, or rarely by dissection or trauma.Thrombosis is typically caused by peripheral vascular disease (atherosclerotic disease that results in vessel blockage), while an embolism is typically of cardiac origin. within the us , ALI is estimated to occur in 14 out of each 100,000 people per annum . With proper surgical care, acute limb ischaemia may be a highly treatable condition; however, delayed treatment (beyond 6 to 12 hours) may result in permanent disability, amputation, and/or death.   In contrast to acute limb ischemia, chronic limb threatening ischemia results from peripheral artery disease that develops over time. While limbs in both acute and chronic limb ischemia could also be pulseless, a chronically ischemic limb is usually warm and pink thanks to a well-developed collateral artery network and doesn't need emergency intervention to avoid limb loss.     The Neo-Latin term ischaemia as written, may be a British version of the word ischemia, and stems from the Greek terms ischein 'to hold'; and haima 'blood'. during this sense, ischaemia refers to the inhibition of blood flow to/through the limb.Acute limb ischaemia can occur in patients through all age groups. people that smoke tobacco cigarettes and have DM are at a better risk of developing acute limb ischaemia. Most cases involve people with atherosclerosis problems.
