At the Supreme Vascular and Interventional Clinic in Singapore, Dr. Manish Taneja provides comprehensive assessment and personalised treatment for patients with peripheral arterial disease and other vascular conditions, helping patients make informed decisions based on their symptoms, imaging findings, and overall vascular health.

What Is Peripheral Arterial Disease?

Peripheral arterial disease occurs when the arteries carrying oxygen-rich blood to the legs become narrowed, reducing circulation to the muscles and tissues. The most common cause is atherosclerosis, a process in which cholesterol, calcium, and other substances accumulate within the artery walls to form plaque. As these arteries become progressively narrower, the legs receive less oxygen during physical activity. This often causes intermittent claudication, pain, cramping, or fatigue in the calf, thigh, or buttock that develops while walking and improves with rest.

In more advanced stages, blood flow may become severely restricted, leading to pain at rest, slow-healing wounds, ulcers, or tissue damage. Without appropriate treatment, severe PAD may increase the risk of limb-threatening complications.

Importantly, PAD rarely occurs in isolation. Because atherosclerosis affects blood vessels throughout the body, patients with PAD may also have narrowing of the arteries supplying the heart, brain, kidneys, or other organs. For this reason, diagnosing PAD provides an opportunity to assess overall vascular health and reduce future cardiovascular risk.

Making Informed Decisions About Peripheral Arterial Disease

Being diagnosed with peripheral arterial disease often raises questions about what happens next. Not every patient requires the same treatment, and management depends on the severity of symptoms, circulation, imaging findings, lifestyle, and overall vascular health.

Our Peripheral Arterial Disease (PAD) Decision-Making Guide explains:

• When leg pain or poor circulation should be investigated
• How vascular specialists assess PAD
• Which imaging tests may be recommended
• When lifestyle modification and medication may be sufficient
• When minimally invasive procedures such as angioplasty or stenting may be considered
• What to expect from long-term monitoring and follow-up care

Whether you are newly diagnosed, seeking a second opinion, or exploring treatment options, understanding the decision-making process can help you feel more confident about your care.

Signs & Symptoms of Peripheral Arterial Disease

The symptoms of peripheral arterial disease vary depending on the location and severity of arterial narrowing. Some people experience only mild discomfort during exercise, while others may have no symptoms until the disease becomes more advanced.

Common signs and symptoms include:

• Pain, cramping, or aching in the calf while walking (intermittent claudication)
• Pain in the thigh, buttock, or hip during activity
• Leg fatigue or heaviness after walking short distances
• Symptoms that improve with rest
• Cold feet or lower legs
• Numbness or weakness in the legs or feet
• Slow-healing cuts, wounds, or ulcers on the feet or toes
• Changes in skin colour or temperature
• Reduced hair growth on the legs
• Weak or absent pulses in the feet
• Pain in the feet or toes while resting, particularly at night

Not every person with PAD experiences pain. In some cases, reduced walking distance, slower wound healing, or persistent coldness in one leg may be the earliest signs of reduced circulation.

Because these symptoms may also occur in conditions affecting the spine, joints, muscles, or veins, a comprehensive vascular assessment is often required to determine whether poor circulation is the underlying cause.

What Causes Peripheral Arterial Disease?

Peripheral arterial disease is most commonly caused by atherosclerosis, a condition in which plaque gradually narrows the arteries and restricts blood flow.

Several factors increase the risk of developing PAD, including:

• Smoking or previous tobacco use
• Diabetes mellitus
• High blood pressure (hypertension)
• High cholesterol
• Increasing age
• Chronic kidney disease
• Obesity
• Physical inactivity
• Family history of cardiovascular disease
• Previous stroke or heart attack

Many of these risk factors are shared with coronary artery disease and stroke. As a result, patients diagnosed with PAD often benefit from a comprehensive assessment of their overall vascular health.

Managing these risk factors is an important part of treatment and can help slow disease progression, reduce complications, and improve long-term cardiovascular health.

How Is Peripheral Arterial Disease Diagnosed?

Diagnosing peripheral arterial disease involves more than confirming the presence of narrowed arteries. A comprehensive vascular assessment helps determine the severity of disease, identify the location of arterial narrowing, evaluate your overall circulation, and develop the most appropriate treatment plan. In the early stages, one of the screening tests is a simple non-invasive test called Ankle Brachial Index (ABI) measurement. This involves measuring blood pressure in the arm and leg simultaneously.

Your consultation typically begins with a review of your medical history, symptoms, cardiovascular risk factors, and walking limitations, followed by a physical examination of the lower limbs.

Depending on your symptoms and clinical findings, your vascular specialist may recommend one or more investigations, including:

• Ankle-Brachial Index (ABI) to compare blood pressure measurements in the arms and ankles
• Duplex ultrasound to assess blood flow and identify narrowed or blocked arteries
• CT Angiography (CTA) to produce detailed images of the arteries
• MR Angiography (MRA) for selected patients requiring further vascular imaging
• Catheter angiography, which may also allow minimally invasive treatment to be performed during the same procedure when appropriate

These investigations help determine the extent of arterial disease while guiding personalised treatment recommendations.

Treatment Options for Peripheral Arterial Disease

Treatment for peripheral arterial disease depends on the severity of symptoms, the degree of arterial narrowing, your overall health, and your personal treatment goals. Many patients can successfully manage PAD through a combination of lifestyle modifications and medication, while others may benefit from minimally invasive endovascular procedures or surgery to restore blood flow.

The aim of treatment is to:

• Improve circulation to the legs
• Relieve pain and walking limitations
• Promote wound healing
• Reduce the risk of limb-threatening complications
• Lower the long-term risk of heart attack and stroke
• Improve overall quality of life

Treatment recommendations are always individualised rather than based solely on imaging findings.

One of the first things done in patients with PAD is to control their risk factors well with proper medical management such as controlling diabetes, hypertension, high cholesterol, and more. 

Lifestyle Modification

Lifestyle changes are an essential part of managing peripheral arterial disease and slowing disease progression.

Your specialist may recommend:

• Smoking cessation
• A structured walking or exercise programme
• Weight management
• Healthy dietary changes
• Cholesterol management
• Blood pressure control
• Diabetes optimisation

These measures not only improve circulation but also reduce the risk of cardiovascular and cerebrovascular disease.

Medication

Medication may be recommended to improve circulation and reduce future vascular complications.

Depending on your individual condition, treatment may include medications that:

• Reduce blood clot formation
• Lower cholesterol
• Improve blood pressure control
• Optimise diabetes management
• Reduce cardiovascular risk

Your medication plan will be tailored to your overall vascular health and existing medical conditions.

When Is Endovascular Treatment Recommended?

Not every patient with peripheral arterial disease requires an intervention. However, minimally invasive endovascular treatment may be considered when symptoms significantly affect daily activities, conservative management has not provided adequate relief, or blood flow has become severely restricted.

Endovascular procedures are performed through a small puncture in the artery using specialised catheters and imaging guidance, avoiding the need for large surgical incisions in many patients. Minimally invasive methods of treatment such as angioplasty are now becoming extremely popular, as they are as effective as surgery with shorter recovery times. For a significant number of patients, this can be done as a day procedure with discharge from the hospital on the same day.

Depending on the location and severity of arterial narrowing, treatment may include:

• Balloon angioplasty
• Atherectomy
• Drug-coated balloon angioplasty
• Drug eluting stents
• Vascular stenting
• Mechanical thrombectomy
• Other catheter-based techniques to improve blood flow
• Devices to remove clots

Compared with traditional open surgery, many endovascular procedures involve shorter recovery times, smaller incisions, and a faster return to normal activities for appropriately selected patients highlighting the benefits offered thanks to the significant recent advances of minimally invasive treatment of PAD. 

When Is Surgery Necessary?

Although many patients can be treated using minimally invasive techniques, surgery may still be the most appropriate option in selected cases.

Surgical bypass may be recommended when:

• Arterial disease is extensive
• Multiple arterial segments are affected
• Endovascular treatment is unlikely to provide durable results
• Previous treatments have not been successful

Your vascular specialist will discuss the benefits, limitations, and expected outcomes of each treatment option before recommending an individualised care plan.

Living Well With Peripheral Arterial Disease

Peripheral arterial disease is a long-term condition that benefits from ongoing monitoring and proactive management.

Successful treatment extends beyond restoring blood flow. Long-term care focuses on preserving circulation, preventing disease progression, reducing cardiovascular risk, and maintaining mobility.

Your follow-up plan may include:

• Monitoring symptoms and walking distance
• Regular vascular examinations
• Repeat ultrasound or vascular imaging when appropriate
• Optimisation of blood pressure, cholesterol, and diabetes
• Smoking cessation support
• Review of medications
• Lifestyle and exercise guidance

Because PAD often reflects more widespread vascular disease, regular follow-up also provides an opportunity to monitor your overall cardiovascular health and reduce the risk of future stroke or heart attack.

Who is at Risk?

Patients with known heart disease and stroke are at high risk of getting peripheral vascular disease as the underlying disease pathology is similar. One of the groups of patients at particular risk in our local population is patients with diabetes. Other risk factors include smoking, hypertension, high cholesterol, and patients with renal failure.

Comprehensive Vascular Care

Peripheral arterial disease is one of many conditions that affect the vascular system. At Supreme Vascular & Interventional Clinic, assessment extends beyond the arteries in the legs to consider your overall circulation, cardiovascular risk factors, and long-term vascular health.

Where appropriate, evaluation may include screening for related vascular conditions affecting the carotid arteries, aorta, or other blood vessels. This comprehensive approach helps ensure that treatment decisions are based on your complete vascular health rather than a single area of disease.

Concerned About Your Circulation?

Whether you're experiencing leg pain while walking, poor wound healing, cold feet, or have been diagnosed with peripheral arterial disease, a comprehensive vascular assessment can help determine the cause of your symptoms and identify the most appropriate treatment pathway.

A specialist consultation may include:

• Review of your symptoms and medical history
• Assessment of circulation and vascular risk factors
• Review of ultrasound, CT, MRI, or angiography imaging
• Recommendations for further investigations where appropriate
• A personalised treatment or long-term management plan
