Limb Ischemia and Chronic Limb-Threatening Ischemia

How these terms are used

Ischemia means a tissue is not getting the blood flow it needs. In the legs, that concern is often related to arterial disease such as PAD.

CLTI is a clinical term physicians may use when PAD is present together with rest pain, a wound that is not healing, or other signs of threatened limb tissue. Only a physician can decide whether that term applies.

Wounds and pain are not a diagnosis

Non-healing sores, rest pain, color change, or a cold limb can have many causes. Those findings do not, by themselves, mean a person has CLTI or needs a particular procedure.

They can still be a reason to seek prompt medical evaluation rather than waiting on online reading.

Why timely evaluation matters

Reduced arterial blood flow can become urgent. A cardiovascular evaluation can help determine whether circulation, infection, nerve problems, or another issue may be contributing.

This practice provides educational information and office evaluation. This page does not claim that every limb-circulation procedure is performed here, and it does not promise limb salvage or any other outcome.

Additional reading

A dedicated patient-education page titled only “CLTI” was not used here because the strongest verified public pages describe PAD, the related arterial condition. The Learn more link goes to American Heart Association education about PAD.

When to contact a physician

Call 911 for a suddenly cold, pale, or severely painful limb, chest pain, or trouble breathing. Call the office if you have been referred for evaluation of circulation concerns or a non-healing lower-extremity wound and the situation is not an emergency.
