Peripheral artery disease: calf pain when walking (claudication)
Peripheral artery disease is chronic narrowing of the leg arteries by atherosclerotic plaque, so that the muscles receive too little blood during exertion. The first symptom is intermittent claudication: pain in the calf muscles when walking that resolves after stopping. The disease progresses, but at this stage its course can be controlled.
Symptoms
- Pain, burning or fatigue in the calf muscles (less often the thigh or buttock) after a certain walking distance, resolving within a few minutes of rest
- A gradually shrinking pain-free walking distance
- Cool skin of the feet, pallor, hair loss, slow healing of minor injuries
- Weakness in the legs on stairs or uphill
- Risk factors: smoking, diabetes, hypertension, dyslipidemia, age over 50
Clinical significance
Peripheral artery disease is a marker of systemic atherosclerosis: such patients have an increased risk of myocardial infarction and stroke. Without treatment, in some patients the disease progresses to limb-threatening ischemia.
When it is urgent
Pain in the foot at rest or at night, an ulcer that does not heal or blackening of a toe mean progression to limb-threatening ischemia: assessment by a vascular surgeon is needed within days.
Sudden pain, coldness, pallor or numbness in a leg: call an ambulance (103 in Ukraine). If these signs appear or sharply worsen over minutes or hours, especially with weakness of the foot or inability to move the toes, this may be acute limb ischemia — a sudden occlusion (blockage) of an artery. Irreversible tissue damage can develop within hours (roughly six), so do not wait until morning, do not warm the leg with a heating pad or hot water, and do not rub it.
Diagnosis at the Center
Ankle-brachial index, duplex ultrasound of the arteries and, when indicated, CT angiography. The work-up takes one or two days.
In diabetes and chronic kidney disease, calcification of the arterial wall makes the arteries of the lower leg poorly compressible by the cuff, so the ankle-brachial index can be falsely normal or elevated (above 1.3–1.4). In these patients toe pressure is also measured and the toe-brachial index calculated, and the arteries are assessed with duplex ultrasound.
Treatment
The foundation is medical therapy (antiplatelet agents, statins), smoking cessation and structured walking. If claudication limits daily activity or the disease progresses, blood flow is restored endovascularly: balloon angioplasty, stenting of the iliac and femoropopliteal arteries, drug-coated balloons. IVUS guidance allows precise stent sizing and a more durable result.
Frequently asked questions
Is a procedure needed if I only have pain when walking?
Not necessarily. At the claudication stage, treatment begins with medication, structured walking and smoking cessation. A procedure is considered when conservative treatment fails or walking distance seriously limits daily life.
Are intravenous infusions of vascular drugs effective?
Infusions do not reopen an occluded artery. Proven benefit comes from antiplatelet agents, statins, structured walking and revascularization.
How long does a stent last?
Years, provided prescribed medication is taken, smoking is stopped and follow-up is kept. Precise IVUS-based sizing reduces the risk of restenosis.
When can I return to normal life?
Walking is allowed the next day; return to work usually within a week.
