Introduction
Chronic limb-threatening ischemia (CLTI) is a condition that occurs when the blood flow to a limb is significantly reduced, leading to tissue damage, pain, and potential amputation. One of the treatment options for CLTI is plantar artery bypass surgery, which involves rerouting blood flow around the blockage in the artery to restore circulation to the affected limb. An estimated 220 to 3500 occurrences of chronic limb-threatening ischemia occur annually per 1 million people. Although it has a reported prevalence of one % to two %, people with known peripheral arterial disease may experience a prevalence as high as 11 %. According to estimates, 5 to 10 % of patients with intermittent asymptomatic peripheral artery disease will develop chronic limb-threatening ischemia over the course of five years. This article will explore the details of this procedure, including its benefits, risks, and recovery.
What Causes Plantar Artery Bypass for Chronic Limb-Threatening Ischemia?
Plantar artery bypass surgery is typically performed to treat chronic limb-threatening ischemia (CLTI), a condition that occurs when the blood flow to a limb is severely reduced. The reduced blood flow can be caused by a variety of underlying conditions, including peripheral artery disease (PAD), atherosclerosis, or blood clots.
The following are the causes of plantar artery bypass for chronic limb:
-
PAD occurs when plaque builds up in the arteries, narrowing them and reducing blood flow to the affected limb. This condition is most commonly caused by lifestyle factors such as smoking, high blood pressure, and high cholesterol, but it can also be the result of genetic factors or other underlying medical conditions.
-
Atherosclerosis is a similar condition that occurs when fatty deposits build up in the walls of the arteries, reducing blood flow to the affected area. This condition is also commonly caused by lifestyle factors such as poor diet, lack of exercise, and smoking.
-
Blood clots can also cause reduced blood flow to the affected limb, either by forming in the affected artery or traveling from another part of the body and becoming lodged in the artery. Blood clots can be caused by a variety of underlying medical conditions, including deep vein thrombosis (DVT), certain medications, or a genetic predisposition to blood clotting disorders.

In cases of CLTI, plantar artery bypass surgery may be recommended as a treatment option to restore blood flow to the affected limb and prevent amputation. The surgery involves rerouting blood flow around the blockage in the plantar artery to restore circulation to the foot.
What Are the Symptoms of Plantar Artery Bypass for Chronic Limb-Threatening Ischemia?
Chronic limb-threatening ischemia (CLTI) is a condition that occurs when blood flow to a limb is significantly reduced, leading to tissue damage, pain, and potential amputation. Plantar artery bypass surgery is a treatment option for CLTI that can restore blood flow and prevent amputation. If someone is experiencing any of these symptoms, it is important to speak to a healthcare professional about options for treatment, including plantar artery bypass surgery. Early intervention and treatment can help prevent further tissue damage and reduce the risk of amputation.
The symptoms of CLTI can vary depending on the severity of the condition, but may include the following:
-
Pain in the affected limb, especially during physical activity or at rest.
-
Sores or wounds on the foot or leg that are slow to heal or do not heal at all.
-
Skin discoloration or changes in skin texture on the foot or leg.
-
Weakness or numbness in the affected limb.
-
Cold or tingling sensations in the affected limb.
-
Poor nail growth or hair loss on the affected limb.
-
Gangrene, or tissue death, in severe cases.
How Plantar Artery Bypass Procedure Performed?
Plantar artery bypass surgery is performed under general anesthesia and typically takes two to four hours. During the procedure, a surgeon will create a new pathway for blood flow to bypass the blockage in the plantar artery, which is located in the foot. To do this, the surgeon will make an incision in the leg and harvest a vein, typically from the thigh or calf area. The vein is then attached to the plantar artery above the blockage and below the knee joint, allowing blood to flow freely to the foot.
What Are the Benefits of Plantar Artery Bypass?
The primary benefit of plantar artery bypass surgery is the restoration of blood flow to the affected limb. By bypassing the blockage, the patient can experience relief from symptoms such as pain, swelling, and skin discoloration. Additionally, the procedure can help prevent further tissue damage and reduce the risk of amputation. Patients who undergo plantar artery bypass surgery often report an improvement in their quality of life and the ability to engage in physical activities that were previously limited.
After the procedure, patients typically spend several days in the hospital to recover. During this time, they will be monitored for any signs of complications and given pain medication as needed. Patients will also receive instructions for caring for their incision site and managing their pain at home. Following discharge from the hospital, patients will need to attend follow-up appointments with their surgeon to monitor their progress and ensure the graft is functioning properly. They may also need to participate in physical therapy to regain strength and mobility in the affected limb.
What Are the Risks and Complications of Plantar Artery Bypass?
As with any surgery, there are risks associated with plantar artery bypass. These include bleeding, infection, blood clots, and damage to surrounding nerves or blood vessels. Patients may also experience pain, swelling, and stiffness in the affected limb after the procedure. In rare cases, the bypass graft may fail, requiring additional surgery.
Conclusion
Plantar artery bypass surgery is a treatment option for patients with chronic limb-threatening ischemia that can help restore blood flow and prevent amputation. While the procedure does carry some risks, the benefits can be significant, including relief from symptoms and improved quality of life. If loved one is experiencing CLTI, speak to a healthcare professional about whether plantar artery bypass surgery may be an appropriate treatment option.
