What is CLI? 

Critical Limb Ischemia is a severe obstruction of the arteries which reduces blood flow to the hand, feet, and legs. This reduction in blood flow will progress to the point of severe pain, skin ulcers, and sores. Ischemia is a severe condition that can cause tissue damage and the loss of limbs.

The symptoms of CLI depend on how quickly blood flow and oxygen are interrupted.
