Limb Salvage Program: Don't Accept Amputation Without a Vascular Opinion

What is limb salvage?

Limb salvage is a coordinated set of treatments aimed at saving a leg or foot that is at risk of amputation, usually because of severely reduced blood flow. The goal is to reopen or reroute the blocked arteries, heal the wound, and preserve a functional limb. For most patients facing amputation from poor circulation, limb salvage offers a real alternative.

Why does a threatened limb happen?

A limb becomes threatened when arteries are so narrowed or blocked that not enough blood reaches the foot to keep tissue alive. This advanced stage of peripheral artery disease is called chronic limb-threatening ischemia (CLTI) — the most severe form of the disease. It shows up as constant pain in the foot at rest, sores or ulcers that won't heal, or areas of dying tissue (gangrene).

CLTI is serious. Research estimates that roughly one in three people face amputation within a year of a CLTI diagnosis if circulation isn't restored. People with diabetes, kidney disease, or a history of smoking are at the highest risk. The encouraging part is that when blood flow is restored in time, the outlook changes dramatically.

Why get a vascular opinion before agreeing to amputation?

Because amputation is often preventable, and a vascular surgeon is the specialist trained to prevent it. Studies show that most major leg amputations are performed without any prior attempt to restore blood flow. A vascular evaluation determines whether the arteries can be reopened — and in many cases, they can.

This is the single most important message of our program. An amputation is permanent. A vascular consultation is not. Asking for one costs you little and can change everything, because the question "can this limb be saved?" is exactly the question a vascular surgeon exists to answer.

Major amputation is also more than the loss of a limb. It is associated with loss of mobility, depression, social isolation, and a higher risk of death. Restoring blood flow and saving the limb avoids that trajectory — and research has found it to be more cost-effective than amputation as well.

How does Dr. Cardentey save limbs?

Limb salvage works by reopening or bypassing the blocked arteries that are starving the foot of blood, then healing the wound. Dr. Cardentey is a board-certified vascular surgeon trained in both minimally invasive and open surgical techniques, which means treatment is matched to your anatomy rather than to a single available tool. Approaches include:

• Angioplasty and stenting — reopening a narrowed artery from the inside through a small puncture.
• Atherectomy — removing plaque from within the artery to restore flow.
• Bypass surgery — rerouting blood around a blocked segment using a graft, often the best option for complex blockages.
• Wound-directed revascularization — targeting blood flow specifically to the part of the foot where the wound needs to heal.

Because the arteries below the knee are small and the disease is often complex, this work rewards experience and a full toolkit. Dr. Cardentey's fellowship training emphasized high-volume open and endovascular surgery for exactly these situations.

Limb salvage is a team effort

Saving a limb is rarely the work of one specialty alone. Restoring blood flow is the vascular surgeon's role — but healing a wound also depends on skilled wound care and, often, podiatry. The national PAD guidelines specifically call for this kind of multidisciplinary foot care.

Cardentey Vascular Care provides the vascular piece — the assessment and the procedures that get blood flowing again — and works alongside your wound care team and podiatrist, not in place of them. If you already have a podiatrist or wound care specialist, we coordinate with them. If you need one, we have a trusted referral network. The patient keeps their care team; we add the vascular expertise that helps the wound finally heal.

Who should come in?

You should be evaluated for limb salvage if you have:

• A foot or leg wound that hasn't healed after two weeks
• Constant pain in the foot or toes, especially at rest or at night
• An area of black or dying tissue on the foot or toes
• Been told you may need an amputation
• Diabetes or kidney disease along with any foot wound or sore

With a threatened limb, time matters. The sooner blood flow is restored, the better the chance of saving the limb.
