  • Intermittent claudication: 

    This is defined as :

    The pain in a muscle (usually the calf) that occurs due to arterial insufficiency and is reproducible as a result of exercise and is relieved by rest.

    It can be categorised using the Fontaine and Rutherford Classification.

    Fontaine Classification   Rutherford Classification
    Stage   Symptoms   Grade Category Symptoms
    I   Asymptomatic <=> 0 0 Asymptomatic
    II IIa Non-disabling intermittent claudication <=> I 1 Mild claudication
            I 2 Moderate claudication
      IIb Disabling intermittent claudication   I 3 Severe claudication
    III   Ischaemic rest pain <=> II 4 Ischaemic rest pain
    IV   Ulceration or gangrene <=> III 5 Minor tissue loss
            III 6 Major tissue loss
  • This can be differentiated from critical limb ischaemia which is defined by the European society of vascular surgery as:

    • persistently recurring ischemic rest pain requiring regular adequate analgesia for more than two weeks with an ankle systolic pressure ≤ 50 mmHg and/or toe systolic pressure ≤ 30 mmHg;
    • ulceration or gangrene of the foot or toes, with an ankle systolic pressure ≤50 mmHg or toe systolic pressure ≤ 30 mmHg.
