Classification of ALI

An ad hoc committee of the Society for Vascular Surgery and the North American Chapter of the International Society for Cardiovascular Surgery created a classification ( Table 1 ) for acute arterial occlusion.[3] Three general classes are recognized:

Class I: Non-threatened extremity; elective revascularization may or may not be necessary.

Class II: Threatened extremity; revascularization is indicated to prevent tissue loss.

Class III: Ischemia has progressed to infarction and salvage of the extremity is not possible.
