APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Acute limb ischaemia is defined as the sudden decrease in limb perfusion that threatens the viability of the limb. Complete or even partial occlusion of the arterial supply to a limb can lead to rapid ischaemia and poor functional outcomes within hours.

Detailed explanation-2: -Acute limb ischemia – Acute limb ischemia is a sudden decrease in limb perfusion that may threaten limb viability and is usually due to acute arterial occlusion; a venous etiology is rare.

Detailed explanation-3: -Critical limb ischemia is an advanced form of peripheral arterial disease (PAD) affecting blood flow in the extremities, while acute limb ischemia is a sudden and rapid decrease in, or loss of, lower limb blood flow.
