Leg Angioplasty and Stenting in Singapore

Leg angioplasty opens a narrowed or blocked artery from inside the blood vessel. A balloon may be used alone or with a stent to support blood flow. These procedures treat selected consequences of peripheral arterial disease (PAD); they do not remove the underlying tendency to develop plaque. The first decision is whether improving that artery's flow is likely to help your symptoms or protect your foot.

When might a leg artery procedure help?

For stable walking pain, treatment usually starts with cardiovascular risk reduction, appropriate medicines and structured exercise. A procedure may be considered when symptoms still substantially restrict daily life. An abnormal scan alone does not make angioplasty necessary. Read about claudication and walking pain.

Rest pain, tissue loss or a wound affected by poor circulation require a different, timely assessment. Here the aim may be to support healing and preserve a useful limb. Infection, available arteries, general health and the person's priorities all influence the plan.

Which symptoms need emergency care?

A suddenly painful, cold or pale foot with new numbness, weakness or difficulty moving it is an emergency. Call 995 in Singapore; do not wait for a planned procedure or clinic reply. Acute loss of blood flow may need urgent clot removal, other revascularisation or surgery. It is not managed as ordinary stable claudication.

How is treatment planned?

Assessment combines your symptoms, foot examination, pressure tests and imaging. Duplex ultrasound may identify the problem; CT, MR or catheter angiography may add the detail needed for planning. Kidney function, contrast reactions, bleeding risk and previous procedures matter. The PAD assessment video article explains this process.

What is the difference between the devices?

What does balloon angioplasty do?

A thin catheter and guidewire pass through a small arterial puncture to the narrowing. Inflation of a balloon widens the channel; the balloon is then removed. Imaging guides treatment. Local anaesthetic is commonly used at the puncture, with other anaesthesia or sedation chosen for the situation.

Why might a drug-coated balloon be considered?

A drug-coated balloon delivers medication to the artery wall to reduce tissue growth that can contribute to recurrent narrowing. It does not leave a permanent scaffold. Whether it is appropriate depends on the artery, lesion and device evidence. Ask why a coated balloon is being proposed and what alternatives apply to you.

When is a stent useful?

A stent is a supporting tube left inside the artery. It may be used when the vessel needs support after balloon treatment or as part of the planned repair. Different stents have different purposes. A stent can also narrow or block later; its presence does not eliminate follow-up.

Is atherectomy needed for every blockage?

No. Atherectomy uses a catheter device to remove or modify plaque in selected cases. It is not a routine extra for every leg angioplasty, and evidence does not establish it as the best option for every calcified artery. Its possible role must be weighed against vessel injury, debris travelling downstream and other procedural risks.

What are the alternatives?

Continuing medical treatment and exercise may be the appropriate choice for stable symptoms. Bypass, endarterectomy or a hybrid operation may better suit other anatomy. With a threatened foot, options should be discussed promptly rather than assuming that the smallest incision gives the best result. The endovascular treatment video introduces the general approach.

What risks should I understand?

Risks include puncture-site bleeding, bruising, vessel damage, clotting, blocked downstream arteries, contrast reactions and kidney injury. Treatment may fail to cross or adequately open the blockage. Further intervention or surgery may be needed; severe complications can threaten the limb or life. Your individual risk depends on the disease and overall health.

What happens after treatment?

The team checks the puncture, circulation and general recovery before deciding when discharge is appropriate. Follow the specific instructions about activity, driving and wound care. Take prescribed antiplatelet or other medicines as directed; do not stop them yourself. Follow-up assesses symptoms, foot health and the treated artery, sometimes using ultrasound. New rest pain, wounds or reduced walking ability deserve review.

How can I discuss my options in Singapore?

For a non-emergency assessment or second opinion, contact Dr Andrew Choong's clinic at Mount Elizabeth Novena Specialist Centre, #09-22, 38 Irrawaddy Road, Singapore 329563. Bring your scan images and reports, medication list and previous procedure details. The consultation can clarify the expected benefit, alternatives and follow-up for your particular problem.
