What Happens to the Arteries
Arteries carry oxygen-rich blood to the legs. In atherosclerosis, cholesterol plaques build up on the artery walls, narrowing the channel and reducing blood flow to the muscles. At rest the supply is usually adequate; during walking the demand rises — and pain sets in, forcing you to stop.
This is fundamentally different from varicose veins: that condition involves impaired venous outflow and blood pooling, whereas here the problem is insufficient arterial inflow. That is why the approach is entirely different — venous procedures such as EVLA and sclerotherapy have no place here.
Atherosclerosis of the leg arteries is often a 'warning light' for systemic atherosclerosis: the same process may be occurring in the heart and brain vessels. Treatment therefore always looks beyond just the legs.
Symptoms: How to Tell Them Apart from Venous Problems
Early Signs
- Intermittent claudication: calf pain during walking that resolves after a short rest
- Cold feet — a persistent sensation of coldness even in a warm environment
- Pallor of the foot, weakened or absent pulse at the foot
- Hair loss on the lower leg, slow nail growth
Signs of Progression
- Pain in the foot at rest, especially at night and when lying down — relieved by dangling the leg
- Non-healing sores and ulcers on the foot and toes
- Darkening, bluish discoloration, or blackening of the toes
- Pain-free walking distance shrinking to just a few dozen meters
Constant foot pain at rest, blackening of the toes, or sudden severe pain with coldness and numbness in the leg are signs of critical ischemia or acute arterial occlusion. This is a limb-threatening emergency — act immediately. Call: +998 99 883-93-21
Causes and Risk Factors
Smoking
One of the most powerful drivers: it sharply accelerates atherosclerosis of the leg arteries and worsens the outlook.
Diabetes mellitus
Damages both arteries and nerves, accelerating the development of ischemia and diabetic foot complications.
High cholesterol
The primary building block of atherosclerotic plaques.
Arterial hypertension
Damages vessel walls and promotes the progression of atherosclerosis.
Age and sex
Risk increases with age; men tend to develop the disease more often and at a younger age.
Physical inactivity and obesity
Aggravate metabolic disturbances and accelerate vascular damage.
Fontaine Stages
The severity of arterial insufficiency is assessed using the Fontaine classification — ranging from asymptomatic to critical. The higher the stage, the more urgently intervention is needed.
- I
Asymptomatic
Arterial narrowing is already present, but there are no complaints. Often discovered incidentally during a check-up.
- II
Intermittent claudication
Leg pain after walking a certain distance. The optimal time to start treatment.
- III
Rest pain
Pain in the foot without exertion, especially at night — a sign of significant ischemia.
- IV
Trophic changes
Ulcers, tissue necrosis, gangrene. Critical ischemia with a real risk of limb loss.
The stage is determined by a vascular surgeon through clinical examination, arterial duplex ultrasound, and blood pressure measurement. Seeking care early often makes it possible to avoid major surgery.
Why Arterial Atherosclerosis Is Dangerous
Without treatment, the disease progresses and can lead to serious consequences.
Critical ischemia
Severe blood supply deficit: constant pain, non-healing wounds — a limb-threatening condition.
Gangrene and amputation
When tissue dies as a result of advanced ischemia, amputation may become necessary — the very outcome that early treatment can help prevent.
Acute arterial occlusion
A sudden blockage of an artery by a thrombus or embolus — an emergency presenting with severe pain and sudden coldness of the limb.
Systemic risks
The same atherosclerotic process in the heart and brain vessels raises the risk of heart attack and stroke.
Assessing Arterial Blood Flow
When arterial disease is suspected, I assess arterial pulses, perform duplex ultrasound of the leg arteries, and measure the ankle-brachial index — this shows where the vessels are narrowed and by how much. It is important not to confuse arterial pain with venous pain, as the approaches are opposite. Book a consultation and we will identify the nature of the problem and map out the next steps.
Book a ConsultationHow Atherosclerosis of the Leg Arteries Is Treated
Treatment depends on the stage. In the early phases, the cornerstone is risk factor control and medication; for significant ischemia, vascular surgery comes into play. As a vascular surgeon, I determine exactly what is right for you.
The Foundation: Risk Factor Control and Medication
At the intermittent claudication stage, the most important steps are quitting smoking, structured walking, and keeping cholesterol, blood pressure, and blood sugar under control, alongside physician-prescribed medication. This slows the disease and extends pain-free walking distance. The regimen is tailored individually by your doctor — self-treatment in the setting of ischemia is dangerous.
For significant ischemia, restoring blood flow surgically is discussed: endovascular techniques (angioplasty, stenting) or open surgery (bypass grafting, arterial reconstruction). Both open and minimally invasive arterial surgery are part of my practice as a vascular surgeon — learn more about me.
Myths About Arterial Atherosclerosis
Myth:Leg pain must mean varicose veins or a vein problem
The Reality:Not necessarily. Pain on walking, cold feet, and pallor of the foot are signs of arterial insufficiency, not venous disease. The mechanisms are opposite, and the treatments differ fundamentally.
Myth:If you've already been smoking for years, quitting won't make a difference
The Reality:Quitting smoking at any stage slows the disease and improves the outlook. It is one of the most effective steps you can take for atherosclerosis of the leg arteries.
Myth:Claudication is just aging — no need to treat it
The Reality:Intermittent claudication is Fontaine stage II, not a normal part of aging. This is precisely when treatment is most effective and can prevent the progression to critical ischemia.
Myth:Vascular creams and rubs will help
The Reality:Topical products have no effect on the inside of an artery. What actually works is risk factor control, medication, and — when necessary — surgical restoration of blood flow.
Prevention
- Quitting smoking completely — the single most important step
- Keeping cholesterol, blood pressure, and blood sugar under control
- Regular, structured walking and physical activity
- A healthy diet and weight management
- Timely treatment of diabetes and related conditions
- If you notice cold feet or leg pain on walking, don't delay a vascular check-up
Frequently Asked Questions
How can I tell arterial pain from venous pain?
Arterial pain comes on during walking (intermittent claudication) and eases after stopping; the legs feel cold and the skin appears pale. Venous heaviness, by contrast, builds up toward the evening and with prolonged standing, and is relieved by elevating the legs. A duplex ultrasound will give a precise answer.
Can this be treated with a laser, the way varicose veins are?
No. Laser and sclerotherapy methods are designed for veins and are not applicable here. For arterial atherosclerosis, treatment means risk factor control, medication, and — for significant ischemia — endovascular or open surgery on the arteries.
What is the ankle-brachial index?
It is a simple measurement: the ratio of blood pressure at the ankle to blood pressure in the arm. It provides an objective assessment of how much blood flow in the leg arteries is reduced, and is part of the standard work-up when atherosclerosis is suspected.
Will I definitely need surgery?
No. In the early stages (intermittent claudication), quitting smoking, structured walking, and medication are often sufficient. Surgery is discussed when ischemia is significant and blood flow needs to be restored. The decision is made individually after a thorough assessment.
