Peripheral artery disease (PAD) — narrowing of the arteries supplying the legs and feet from atherosclerosis — is a common, serious, and frequently under-recognized condition that profoundly affects foot health. PAD affects approximately 8.5 million Americans over age 40 and is the leading cause of non-traumatic lower extremity amputation when combined with diabetes. At Balance Foot & Ankle, Dr. Tom Biernacki, DPM evaluates and co-manages PAD-related foot complications in Howell and Bloomfield Hills, Michigan. Call (810) 206-1402 to schedule a vascular foot evaluation.

Quick Answer: What Is Peripheral Artery Disease?

Peripheral artery disease is atherosclerotic plaque buildup in the arteries supplying the legs and feet — the same process that causes coronary artery disease in the heart. Reduced arterial blood flow impairs oxygen delivery to foot tissues, slowing wound healing, reducing resistance to infection, and causing ischemic pain. The classic symptom is intermittent claudication — cramping leg pain with walking that resolves with rest. In severe PAD, pain occurs at rest (critical limb ischemia) and wounds that would heal normally in healthy patients become chronic non-healing ulcers in PAD patients. Risk factors: diabetes, smoking, hypertension, hyperlipidemia, age over 50.

How PAD Affects the Foot Specifically

PAD manifests in the foot through several mechanisms. Impaired wound healing: Even minor skin injuries — blisters, callus debridement, ingrown toenail procedures — fail to heal in PAD patients because oxygen delivery to the healing wound is insufficient. Trophic changes: Chronic ischemia produces characteristic skin changes — hairless lower legs and dorsum, shiny atrophic skin, thickened nails, pallor on elevation (Buerger’s test), dependent rubor (redness when foot is in a dependent position). Ischemic ulceration: Punched-out, painful ulcers on the tips of toes, between toes, or at pressure points — distinct from venous ulcers (which are above the ankle, weeping, irregular edges) and diabetic neuropathic ulcers (which are painless, over pressure points, with good surrounding circulation).

Diagnosing PAD: Ankle-Brachial Index and Beyond

The ankle-brachial index (ABI) is the primary screening test — the ratio of systolic blood pressure measured at the ankle to that measured at the arm. Normal ABI: 1.0–1.4. Borderline: 0.91–0.99. Mild PAD: 0.70–0.90. Moderate PAD: 0.40–0.69. Severe/critical limb ischemia: <0.40. Important limitation: ABI is falsely elevated (often >1.4) in diabetics and elderly patients with medial arterial calcification — the vessels are non-compressible. In these patients, toe-brachial index (TBI) — measured with photoplethysmography at the great toe — is a more reliable screening test; normal TBI is ≥0.7.

When ABI or TBI is abnormal, vascular surgery consultation is indicated for formal duplex ultrasound arterial mapping, CT angiography, or magnetic resonance angiography to identify the level and severity of stenosis and determine revascularization candidacy.

Implications for Podiatric Procedures in PAD Patients

Podiatric procedures in PAD patients carry significantly elevated complication risk. Before any elective foot surgery in a patient with PAD risk factors (diabetes, smoking, hypertension, claudication, or abnormal pulses), an ABI measurement is mandatory. Patients with ABI <0.5 or critical limb ischemia should be referred for vascular surgery revascularization before elective podiatric procedures are considered. Even “minor” procedures — ingrown toenail matrixectomy, hammertoe correction, bunion surgery — can result in non-healing wounds and limb-threatening complications in patients with unrecognized severe PAD.

PAD + Diabetes: The Most Dangerous Combination

Diabetes and PAD together create the highest-risk foot environment in medicine. Diabetic neuropathy eliminates pain sensation — the patient cannot feel ischemic rest pain or wound pain. PAD impairs healing. Diabetic immunopathy reduces infection resistance. The result: painless wounds that develop, expand, become infected, and reach bone (osteomyelitis) without the patient being aware. Studies show that combined diabetic PAD patients have a 20× higher major amputation risk than the general population. Annual comprehensive foot examinations with ABI screening for all diabetic patients over 50 — or earlier with risk factors — is the clinical standard of care.

Conservative Management of PAD-Related Foot Problems

For patients with PAD, conservative foot care focuses on: pressure relief and offloading — total contact casting or removable cast walkers for ischemic ulcers; protective footwear — extra-depth therapeutic shoes that eliminate all focal pressure on ischemic skin; moisture management — avoiding maceration between toes (increases infection risk); nail and callus care — regular, careful debridement to prevent callus-related pressure ulcers; and smoking cessation — the single most impactful intervention for PAD progression. MLS laser therapy is used in our clinic to stimulate angiogenesis and wound healing in PAD patients who are not revascularization candidates.

Most Common Mistake with PAD and Foot Health

The most common mistake: attributing leg pain and foot cold intolerance entirely to neuropathy without screening for PAD. Many diabetic patients with concurrent PAD are told their symptoms are “just nerve damage” when the superimposed arterial component is treatable and its treatment would dramatically improve wound healing and quality of life. Any diabetic patient with cold feet, leg pain with walking, hair loss on the dorsum, or shiny atrophic skin should have an ABI measurement — a simple, non-invasive, 10-minute bedside test.

When to Seek Urgent Vascular Evaluation

Seek same-day or emergency evaluation for: rest pain in the foot at night that requires hanging the leg off the bed; a cold, pale, pulseless foot after a period of sitting (acute arterial occlusion — surgical emergency); any non-healing foot wound in a patient with known PAD; or new onset foot discoloration (blue-black toe — acute digital ischemia). Call (810) 206-1402 for urgent evaluation at Balance Foot & Ankle — Howell and Bloomfield Hills, Michigan. We coordinate directly with vascular surgery when emergent revascularization is needed.

Frequently Asked Questions

What causes this condition?

Causes include mechanical stress, biomechanical imbalance, age-related changes, and sometimes systemic disease. Our clinical exam plus imaging identifies the specific driver.

Can it go away on its own?

Mild cases sometimes resolve with rest and supportive footwear. Persistent symptoms past 4-6 weeks rarely resolve without active treatment.

Is surgery required?

Most patients resolve with non-surgical care. Surgery is reserved for refractory cases or structural deformity.
