Acute limb ischaemia (ALI) occurs when there is a sudden lack of blood flow to a limb [1] within 14 days of symptoms onset. [2] On the other hand, when the symptoms exceed 14 days, [ 3 ] it is called critical limb ischemia (CLI).

Sores/ulcers on the affected limb that do not heal; In individuals with severe PAD, complications may arise, including critical limb ischemia and gangrene. Critical limb ischemia occurs when the obstruction of blood flow in the artery is compromised to the point where the blood is unable to maintain oxygenation of the tissue at rest. [19]
The signs and symptoms of ischemia vary, as they can occur anywhere in the body and depend on the degree to which blood flow is interrupted. [4] For example, clinical manifestations of acute limb ischemia (which can be summarized as the "six P's") include pain, pallor, pulseless, paresthesia, paralysis, and poikilothermia. [8]

Critical limb ischemia is diagnosed by the presence of ischemic rest pain, and an ulcers that will not heal or gangrene due to insufficient blood flow. [3] Insufficient blood flow may be confirmed by ankle-brachial index (ABI), ankle pressure, toe-brachial index (TBI), toe systolic pressure, transcutaneous oxygen measurement (TcpO2 ), or skin perfusion pressure (SPP).
