Peripheral Arterial Stenting in Singapore
Minimally Invasive Treatment for Narrowed or Blocked Arteries
Peripheral arterial stenting is a minimally invasive endovascular procedure used to treat selected narrowed or blocked arteries outside the heart and brain.
The procedure is commonly used for peripheral arterial disease (PAD), particularly when narrowing or blockage affects blood flow to the legs.
During peripheral arterial stenting, a thin catheter is inserted in the groin or wrist area then guided through the blood vessels to the narrowed or blocked artery. A stent, a small mesh tube, is then positioned within the artery to help keep the vessel open and improve blood flow.
Stenting may be performed following angioplasty or alongside other endovascular treatments, depending on the location and characteristics of the arterial disease.
At the Supreme Vascular and Interventional Clinic, vascular treatment is led by Dr. Manish Taneja, a dual-trained neurointerventional and peripheral vascular intervention specialist.
With expertise spanning the brain and body, our specialized clinic provides specialist-led vascular assessment, minimally invasive treatment and continuity of care under one roof.

What Is Peripheral Arterial Stenting?
Peripheral arterial stenting is a catheter-based treatment used to help keep a narrowed or blocked artery open.
Peripheral arteries are blood vessels outside the heart and brain that supply blood to areas such as the legs, arms and other parts of the body. When plaque builds up inside an artery, the vessel can become narrowed or blocked. This can reduce blood flow and cause symptoms such as leg pain when walking, reduced mobility or, in more advanced cases, pain at rest or wounds that are slow to heal.
During peripheral arterial stenting, a small mesh tube called a stent is positioned within the affected artery. The stent acts as a scaffold that helps support the artery and maintain an opening for blood flow.
Peripheral arterial stenting may be performed after angioplasty or as part of a broader endovascular revascularisation strategy.
How Does Peripheral Arterial Stenting Work?
Supporting a Narrowed or Blocked Artery
Before treatment, vascular imaging is used to identify the location and severity of the arterial narrowing or blockage.
A thin catheter is guided through the blood vessels towards the affected artery. Angioplasty may first be performed to widen the narrowed section and prepare the artery for stenting. The stent is then positioned across the treated area and expanded to support the artery.
Imaging is used to assess the treated artery and confirm that blood flow has improved.
The catheter is removed after the planned treatment has been completed.
Key Difference: Angioplasty uses a balloon to widen a narrowed artery, while a stent provides ongoing structural support to help keep the treated artery open.
When Might Peripheral Arterial Stenting Be Recommended?
Peripheral arterial stenting may be considered when arterial narrowing or blockage is significantly affecting blood flow and an endovascular treatment approach is appropriate.
Your specialist will consider:
- The location of the blockage
- The length and severity of the narrowing
- Your symptoms
- The extent of peripheral arterial disease
- The condition of the surrounding arteries
- Previous vascular treatments
- Your overall health
- Whether angioplasty alone may be sufficient
- Whether another treatment may provide a better result
Not every patient with PAD requires a stent.
Depending on the individual circumstances, treatment may involve medication and risk-factor management, angioplasty, atherectomy, drug-coated balloon treatment, stenting or another revascularisation procedure.
Peripheral Arterial Stenting for Peripheral Arterial Disease
Restoring Blood Flow to the Legs
Peripheral arterial disease occurs when arteries supplying the limbs become narrowed or blocked, most commonly because of atherosclerosis.
Reduced blood flow can cause symptoms such as:
- Leg pain when walking
- Calf or thigh discomfort with activity
- Reduced walking distance
- Leg or foot pain at rest
- Coldness in the affected limb
- Slow-healing wounds
- Changes in skin colour
- Reduced circulation to the foot
The severity of symptoms and the underlying arterial disease vary considerably between patients.
When intervention is appropriate, peripheral arterial stenting can help restore blood flow through a significantly narrowed or blocked artery.
Peripheral Arterial Stenting vs Angioplasty
Understanding the Difference
Angioplasty and stenting are often used together, but they are not the same treatment.
| Angioplasty | Peripheral Arterial Stenting |
|---|---|
| Uses a balloon to widen the narrowed artery | Uses a mesh stent to support the artery |
| Balloon is removed after treatment | Stent remains within the artery |
| May be sufficient in selected cases | May be used when additional structural support is needed |
| Can prepare an artery for stenting | May follow angioplasty |
| Focuses on widening the vessel | Helps maintain the treated vessel's opening |
In selected patients, angioplasty alone may provide an adequate result.
In others, a stent may be recommended to provide additional support and maintain blood flow.
Peripheral Arterial Stenting and Atherectomy
When Plaque Modification May Be Needed
Some peripheral arterial blockages contain extensive or heavily calcified plaque.
In selected cases, atherectomy may be used to remove or modify plaque before angioplasty or stenting. The purpose is to prepare the artery for subsequent treatment and improve the effectiveness of the overall endovascular procedure.
Whether atherectomy, angioplasty, stenting or a combination is appropriate depends on the characteristics of the individual artery.
Potential Benefits of Peripheral Arterial Stenting
Minimally Invasive Restoration of Blood Flow
For appropriately selected patients, peripheral arterial stenting may provide several potential benefits.
Improves Blood Flow
Opening a significantly narrowed or blocked artery can improve circulation to the affected limb.
May Improve Walking-Related Symptoms
Improved blood flow may help reduce symptoms such as leg pain during walking in appropriately selected patients.
Supports the Treated Artery
The stent provides structural support to help maintain the opening of the treated vessel.
Minimally Invasive Approach
Treatment is performed through a catheter rather than open vascular surgery.
Can Be Combined With Other Treatments
Stenting may be combined with angioplasty, atherectomy or other endovascular techniques when appropriate.
It is important to remember: The benefits of treatment vary between patients. The decision to place a stent depends on the location and characteristics of the arterial disease and the individual's symptoms and overall health.
What Are the Potential Risks and Limitations?
Understanding the Risks of Peripheral Arterial Stenting
Like all vascular procedures, peripheral arterial stenting carries potential risks.
Potential risks may include:
- Bleeding or bruising at the catheter access site
- Stent blockage or migration
- Re-narrowing within or around the stent
- Reaction to contrast dye
- Need for repeat treatment
The risks vary according to the location and complexity of the arterial disease, the type of stent used and the patient's overall health.
Your specialist will discuss the potential benefits, risks and alternatives before recommending treatment.
Recovery After Peripheral Arterial Stenting
What Can You Expect After Treatment?
Following peripheral arterial stenting, you will be monitored while your circulation and catheter access site are assessed.
Your recovery depends on the location and complexity of the treatment and your overall health.
Your specialist will provide personalised advice regarding:
- Caring for the catheter access site
- Prescribed medications
- Physical activity
- Returning to normal activities
- Follow-up appointments
- Vascular imaging where required
- Managing cardiovascular risk factors
Long-term management is important because stenting treats the arterial narrowing but does not remove the underlying causes of peripheral arterial disease.

Frequently Asked Questions About Peripheral Arterial Stenting
What is peripheral arterial stenting used for?
It is commonly used to treat selected cases of peripheral arterial disease where narrowing or blockage is significantly affecting blood flow.
Is peripheral arterial stenting the same as angioplasty?
No. Angioplasty uses a balloon to widen a narrowed artery, while a stent provides structural support to help keep the treated artery open.
Can angioplasty and stenting be performed together?
Yes. Angioplasty is often performed before stent placement to widen the narrowed artery and prepare it for the stent.
Does every patient with PAD need a stent?
No. Some patients can be managed with medication and lifestyle measures, while others may be suitable for angioplasty, atherectomy, drug-coated balloon treatment or another intervention.
Can peripheral arterial stenting improve leg pain?
In appropriately selected patients, restoring blood flow may improve symptoms such as leg pain during walking.
How long does a peripheral arterial stent last?
A stent is intended to remain in the artery permanently, but the treated artery can narrow again over time, making follow-up important.
What happens after peripheral arterial stenting?
Patients are monitored after treatment and receive personalised advice regarding medication, activity, follow-up and management of cardiovascular risk factors.
Can an artery narrow again after stenting?
Yes. Re-narrowing can occur within or around a stent in some patients, which is why ongoing vascular follow-up is important.
