Peripheral Arterial Disease Care

What You Need To Know

Understanding peripheral arterial disease and how it affects the feet.

Peripheral Arterial Disease and the Feet

Peripheral arterial disease (PAD) and related vascular conditions occur when the arteries supplying blood to the feet and legs become narrowed or blocked, reducing oxygen and nutrient delivery to the tissues. This can lead to pain, numbness, slow-healing wounds, and in severe cases, tissue death. Related conditions we evaluate include ischemic foot, acrocyanosis, and erythromelalgia, each of which affects circulation and comfort in the extremities.

Common symptoms include persistent foot pain, especially during walking or at rest, cold or pale skin, numbness, tingling, or weakness, slow-healing sores or ulcers, skin color changes including blue or dark discoloration, and loss of hair or brittle nails on the foot. Some patients also notice bluish discoloration, burning pain, or elevated skin temperature depending on the underlying condition.

Causes and risk factors include atherosclerosis, diabetes and diabetic vascular complications, smoking, high blood pressure, high cholesterol, blood clots or emboli, chronic kidney disease, and injury or trauma that restricts blood flow. PAD is often associated with cardiac disease and other systemic conditions.

Diagnosis begins with a physical examination, review of medical history, and assessment of symptoms. Tests may include ankle-brachial index (ABI) measurements, Doppler ultrasound, angiography, or other imaging studies to evaluate blood flow. If you notice persistent foot pain, color changes, or slow-healing wounds, contact the Foot Care Center for a personalized evaluation.

Vascular Testing and Treatment Options

At the Foot Care Center, our foot and ankle specialists perform an evaluation of your baseline circulatory status by placing a device similar to a blood pressure cuff around your legs. This pain-free test measures your circulatory flow and provides the information needed to determine if additional vascular testing is required. Complete vascular testing is especially useful in treating high-risk diabetic patients to prevent complications from poor circulation.

Prevention is key. Early diagnosis and treatment of PAD and related disorders can help prevent future issues such as ulceration, gangrene, and amputation. Lifestyle and medical management may include quitting smoking, controlling blood pressure and cholesterol, regular exercise to improve circulation, medications to improve blood flow, and pain management for discomfort caused by ischemia.

When circulation is significantly compromised, advanced treatments may be recommended. These can include endovascular procedures such as angioplasty or stenting to restore blood flow, bypass surgery in severe cases of blocked arteries, and dedicated wound care for ulcers or sores to prevent infection. In extreme cases where tissue cannot be saved, amputation may be necessary.

Without treatment, PAD can lead to non-healing ulcers, infection, gangrene, chronic pain, and reduced mobility. With early intervention and a personalized care plan, most patients can protect their circulation, manage symptoms, and maintain an active daily life.
