Peripheral Arterial Disease (PAD) Treatment in Glendale, AZ
Peripheral arterial disease (PAD) is a serious circulatory condition that affects millions of Americans — and one that dramatically increases the risk of foot complications, non-healing wounds, and limb loss when undetected or unmanaged. Many patients are unaware they have PAD because symptoms can develop gradually and quietly. At Sole Foot & Ankle Specialists, our board-certified podiatrists play a critical role in identifying PAD, managing its foot-related complications, and coordinating care with vascular specialists to protect the health and function of your lower extremities.
What Is Peripheral Arterial Disease?
Peripheral arterial disease (PAD) is a form of atherosclerosis — the buildup of plaque (fatty deposits, cholesterol, calcium, and fibrous tissue) within the walls of the arteries that supply blood to the legs and feet. As plaque accumulates, the arteries narrow and harden, progressively reducing blood flow to the lower extremities. This reduced circulation has profound consequences for the feet:
- Decreased delivery of oxygen and nutrients to foot tissues
- Impaired immune cell delivery, reducing the ability to fight infection
- Severely compromised wound healing capacity
- Increased risk of non-healing ulcers, gangrene, and amputation
PAD is closely linked to diabetes — diabetic patients are at 2 to 4 times higher risk of developing PAD than non-diabetic individuals, and the combination of PAD and diabetic neuropathy creates the highest risk environment for limb-threatening complications. PAD is also strongly associated with cardiovascular disease — patients with PAD have a significantly elevated risk of heart attack and stroke.
Symptoms of Peripheral Arterial Disease
PAD symptoms range from absent (asymptomatic PAD, detected only by screening) to severe:
- Intermittent claudication: The classic symptom — cramping, aching, or fatigue in the calf, thigh, or buttock muscles during walking or exercise that is relieved by rest. The claudication distance (how far you can walk before pain forces you to stop) decreases as PAD progresses.
- Coldness in the lower leg or foot compared to the other side
- Skin color changes — pallor when the leg is elevated, dependent rubor (redness) when the leg is lowered
- Shiny, hairless, or thin skin on the lower legs and feet
- Weak or absent pulses in the feet or ankles
- Slow-growing toenails
- Rest pain (critical limb ischemia): Severe burning or aching pain in the foot at rest, typically worse at night, indicating severely compromised circulation
- Non-healing wounds or foot ulcers — particularly on the toes, heel, or between toes
- Gangrene — blackening and death of tissue from complete loss of blood supply
Risk Factors for PAD
Understanding your risk is the first step toward prevention and early detection:
- Smoking: The single most significant modifiable risk factor for PAD — smokers have a 4-fold increased risk, and smoking cessation is the most impactful intervention
- Diabetes: See our Diabetic Foot page — diabetes dramatically accelerates atherosclerotic plaque formation in peripheral vessels
- High blood pressure (hypertension) — damages arterial walls and promotes plaque buildup
- High cholesterol (hyperlipidemia) — accelerates atherosclerosis
- Age 50+ — risk increases progressively with age; those over 65 are at highest risk
- Obesity and physical inactivity
- Family history of PAD, heart disease, or stroke
- Chronic kidney disease
How We Diagnose PAD at Sole Foot & Ankle Specialists
Our podiatrists are trained to recognize PAD signs and perform non-invasive vascular assessment during every comprehensive foot examination for at-risk patients. Diagnostic tools include:
- Ankle-brachial index (ABI): A simple, non-invasive test that compares blood pressure at the ankle to the arm — a ratio below 0.9 indicates PAD. This is the primary screening tool and can be performed in our office at your visit.
- Pulse palpation — assessment of pedal pulses at the dorsal foot and posterior tibial artery
- Skin and capillary refill assessment
- Doppler waveform analysis for detailed vascular evaluation when needed
- Referral for vascular imaging (arterial duplex ultrasound, CTA, MRA) when further workup is needed before revascularization planning
PAD Treatment and Management in Glendale, AZ
Our podiatric approach to PAD focuses on protecting the feet from complications, managing existing wounds, and coordinating vascular care:
- Wound management: Expert care of ischemic foot ulcers and wounds with advanced dressings, infection control, and specialized offloading — recognizing that ischemic wounds require revascularization before healing can occur
- Vascular specialist referral: Prompt referral for angioplasty, stenting, or surgical bypass when ABI findings or clinical presentation indicate significant flow-limiting disease
- Protective footwear: Custom orthotics and diabetic footwear to prevent pressure injuries in patients with impaired healing
- Risk factor management coordination: Collaboration with your primary care physician on smoking cessation, blood sugar control, blood pressure management, and lipid-lowering therapy
- Supervised walking programs: Supervised exercise therapy is a first-line non-invasive treatment for intermittent claudication that can significantly improve walking distance
- Antiplatelet therapy: Aspirin or clopidogrel as prescribed by your physician to reduce cardiovascular and limb events
- Surgical intervention: Minor or major amputation when tissue death is irreversible — our goal is always to preserve as much functional limb as possible through timely intervention. See our Foot Surgery page.
Frequently Asked Questions About Peripheral Arterial Disease
Can PAD be reversed?
Atherosclerotic plaque cannot be fully reversed, but its progression can be significantly slowed or stabilized with aggressive risk factor management — smoking cessation, blood sugar control, statin therapy, blood pressure management, and regular exercise. Revascularization procedures (angioplasty, stenting, or bypass surgery) can restore meaningful blood flow to limb-threatening segments of arteries. The goal of PAD management is to maintain adequate circulation, prevent progression to critical limb ischemia, and reduce cardiovascular risk.
How is PAD different from venous insufficiency?
PAD involves arterial disease — narrowed arteries that restrict oxygenated blood flow to the extremities. Venous insufficiency involves the venous system — damaged valves that cause blood to pool in the legs rather than return efficiently to the heart. Both cause leg and foot symptoms but differ in character: PAD causes pain with exertion (claudication) and rest pain in advanced stages; venous insufficiency causes leg heaviness, swelling, and skin changes (usually on the lower leg), and is often worse after prolonged standing. Both conditions can be present simultaneously and both affect wound healing.
If I have PAD, what should I never do?
Patients with PAD should: never smoke or allow secondary smoke exposure; never go barefoot, as minor foot trauma can create wounds that won’t heal; never use heating pads or hot water bottles on the feet (reduced sensation and impaired circulation increase burn risk); never use sharp instruments to trim nails or corns at home; and never ignore any wound, discoloration, or skin change on the feet — contact your podiatrist immediately. These precautions are lifesaving in patients with significant PAD.
What is critical limb ischemia, and is it an emergency?
Critical limb ischemia (CLI) is the most severe stage of PAD, characterized by rest pain (constant pain in the foot at rest, often at night), non-healing ulcers, or gangrene. CLI indicates blood flow is so severely compromised that limb tissues are dying. It is a medical emergency — without prompt revascularization or surgical intervention, major amputation within 6 to 12 months is required in a substantial proportion of patients. If you or a family member develops CLI symptoms, seek immediate evaluation at our office or an emergency department.
What is the ankle-brachial index (ABI), and should I be screened?
The ankle-brachial index is a simple, painless test performed in our office using a blood pressure cuff and a handheld Doppler device. Blood pressure is measured at the ankle and the arm; the ratio indicates the degree of arterial obstruction. Screening is recommended for: adults over 65, adults 50 to 64 with a history of smoking or diabetes, adults of any age with leg pain on walking, and any diabetic patient with a foot wound. The test takes minutes and can identify PAD before it causes symptoms or complications.
Will PAD prevent my foot wound from healing?
Significant PAD severely impairs wound healing. Oxygen and nutrients needed for cellular repair are delivered by blood — when blood flow is restricted, healing is compromised or impossible. Most ischemic foot ulcers will not heal until blood flow is restored through revascularization. This is why vascular assessment is a standard part of our initial evaluation for any foot wound in a high-risk patient. Attempting to treat a wound without addressing the underlying ischemia is ineffective and delays the care that could save the limb.
How does quitting smoking help PAD?
Smoking is the most powerful modifiable risk factor for PAD. Nicotine causes arterial spasm, carbon monoxide reduces oxygen delivery, and smoking’s inflammatory effects accelerate atherosclerotic plaque formation. Quitting smoking is the single most effective intervention for slowing PAD progression — studies show smoking cessation reduces amputation risk, improves claudication symptoms and walking distance, and significantly reduces cardiovascular events. Our team can connect you with smoking cessation resources as part of comprehensive PAD care.
