PeripheralAngioplasty
Restore Blood Flow.
Relieve Leg Pain.
Protect Your Limb.
A minimally invasive procedure that opens narrowed or blocked arteries in the legs, helping restore blood flow to the muscles, feet and tissues that need it.
What Is Peripheral Artery Disease?
Peripheral Artery Disease, or PAD, happens when arteries supplying the limbs become narrowed or blocked.
Although PAD can affect the arms, it most commonly affects the legs and feet. The usual cause is atherosclerosis— a gradual buildup of plaque inside the artery.
As an artery becomes narrower, less oxygen-rich blood reaches the muscles and tissues of the leg.
Why does this matter?
PAD is more than a circulation problem in the legs. It can also be a sign of disease affecting the cardiovascular system and is associated with increased cardiovascular and limb-related risks.
Early diagnosis and appropriate treatment are important.Why Do Arteries Become Narrowed or Blocked?
The most common cause is atherosclerosis, where plaque gradually builds up inside the artery.
Diabetes
Smoking or tobacco use
High blood pressure
High cholesterol
Chronic kidney disease
Increasing age
Physical inactivity
Previous cardiovascular disease
What Symptoms Should You Look For?
Pain or heaviness
that appears while walking
The discomfort often improves after stopping and resting.
Pain while walking
Cramping or aching in the calf, thigh, buttock or foot that improves after resting.
Cold or numb feet
One foot or leg may feel colder, weaker or more numb than the other.
Slow-healing wounds
Cuts, ulcers or wounds on the feet may take much longer than expected to heal.
Pain at rest
Advanced disease can cause pain in the foot or leg even when you are resting.
Severe PAD can progress to chronic limb-threatening ischemia, where inadequate blood flow may cause rest pain, tissue loss or gangrene.
How Is PAD Diagnosed?
Your vascular specialist first considers your symptoms, medical history and circulation. Tests can then help identify where blood flow is reduced.
Ankle-Brachial Index
This test compares blood pressure at your ankle with blood pressure in your arm to look for reduced blood flow to the legs.
Arterial Doppler
A Doppler ultrasound uses sound waves to assess blood flow and identify areas where circulation may be reduced.
CT or MR Angiography
These scans create detailed images of the arteries and can help locate and assess narrowed or blocked areas.
Peripheral Angiography
Contrast dye and X-ray imaging are used to clearly show narrowed or blocked arteries, especially when an endovascular treatment is being considered.
So, What Exactly Is Peripheral Angioplasty?
In simple terms, peripheral angioplasty widens a narrowed or blocked artery to improve blood flow to the limb.
Instead of making a large surgical incision, a doctor uses a thin catheter to reach the affected artery. A small balloon is then inflated inside the narrowed area.
The balloon gently expands the narrowed segment.
This creates more space for blood to flow through the vessel. In selected cases, a stent — a small mesh tube — may be placed inside the artery to help keep it open.
How Does Peripheral Angioplasty Work?
The procedure is performed in carefully controlled stages using imaging to guide the catheter and assess blood flow.
Vascular Access
A small puncture is made to access an artery. A large surgical incision is usually not required.
What Does Peripheral Angioplasty Actually Do?
The goal is not simply to "remove a blockage."
The main goal is to improve blood flow to the affected limb.
Reduce walking-related leg pain
Improve walking ability
Improve blood supply to the foot
Support healing of ischemic wounds
Relieve ischemic rest pain
Help preserve the limb in severe disease
Which Arteries Can Be Treated?
Peripheral angioplasty can be used to treat disease in arteries supplying the legs and feet, depending on the location and characteristics of the blockage.
Iliac arteries
Femoral arteries
Popliteal artery
Tibial arteries
Lower-leg arteries
Foot arteries
When Is Peripheral Angioplasty Considered?
Treatment usually starts with appropriate medical management, risk-factor control and lifestyle measures.
For patients with functionally limiting claudication whose symptoms remain troublesome despite appropriate treatment and structured exercise, revascularization may be considered.
Significant lifestyle-limiting claudication
Persistent symptoms despite appropriate treatment
Chronic limb-threatening ischemia
Ischemic rest pain
Non-healing ischemic wounds
Tissue loss or gangrene associated with inadequate blood flow
Can Angioplasty Avoid Open Surgery?
Sometimes — but not always. The best treatment depends on the individual patient and the anatomy of the disease.
Peripheral Angioplasty
Bypass Surgery
What Are the Benefits?
Minimally invasive
Treatment is performed through a small vascular access point rather than a large surgical incision.
Improves blood flow
Opening a narrowed artery can increase blood flow to the affected leg or foot.
May improve walking
For appropriately selected patients, restoring blood flow can improve walking ability and quality of life.
Supports wound healing
Improved circulation can help support healing when poor arterial blood flow is contributing to a wound.
What Happens After the Procedure?
After the procedure, the medical team monitors the access site and circulation in the treated limb.
Leg and foot circulation
Symptoms and walking ability
Wound healing, when applicable
Pulse examination
ABI or vascular ultrasound when clinically indicated
PAD is a chronic condition.
Treatment does not end with angioplasty. Long-term management remains important, including risk-factor control, exercise, smoking cessation when applicable and guideline-directed medical therapy.
What Are the Possible Risks?
Although peripheral angioplasty is minimally invasive, it is still a vascular procedure. Your specialist will discuss your individual risks before treatment.
Bleeding or bruising at the access site
Injury to the artery
Blood clot or embolization
Re-narrowing of the treated artery
Infection
Contrast-related complications
Kidney-related complications in susceptible patients
Rare need for emergency surgery
A Simple Way to Understand Peripheral Angioplasty
Think of the artery like a pipe. When plaque builds up, the passage becomes narrow.
Frequently Asked Questions
Clear answers to some common questions about peripheral angioplasty and PAD.
Talk to Our Vascular Team→No. Peripheral angioplasty treats narrowed or blocked arteries and is used for Peripheral Artery Disease. Varicose-vein procedures treat problems involving the venous system. They are different vascular conditions and require different treatments.
No. Peripheral angioplasty is an endovascular procedure performed on peripheral arteries. It uses catheter access rather than open surgery on the heart.
No. Many people with PAD are initially treated with risk-factor management, appropriate medical therapy and structured exercise. Revascularization is considered when it is clinically appropriate.
Not necessarily. Some arterial narrowings can be treated without a stent. Whether a stent is appropriate depends on the artery involved, the characteristics of the blockage and the result of angioplasty.
Angioplasty treats a particular arterial narrowing or blockage and can improve blood flow. It does not remove the underlying tendency to develop atherosclerosis, so long-term management remains important.
In patients with severe PAD and chronic limb-threatening ischemia, restoring blood flow can help relieve ischemic pain, support wound healing and help preserve limb function. The appropriate treatment depends on the individual patient.
Recovery varies depending on the procedure, access site, artery treated and your overall health. Because angioplasty is minimally invasive, recovery is generally less extensive than recovery after open bypass surgery.
Your circulationmatters.
Leg pain while walking, unexplained coldness of the feet or a wound that does not heal can sometimes be signs of reduced arterial blood flow.
Early vascular assessment can identify PAD and help determine the right treatment — from medical management and exercise to minimally invasive revascularization when appropriate.
