What is Peripheral Vascular Disease?
Peripheral Vascular Disease (PVD), also known as peripheral artery disease (PAD), is a common and potentially serious condition that affects the blood vessels outside the heart and brain. These peripheral arteries and veins play a crucial role in circulating blood throughout the body. PVD is essentially a circulatory disorder where narrowed blood vessels reduce blood flow to the limbs, particularly the legs and feet. This often occurs due to a buildup of fatty deposits (atherosclerosis) in the arteries.
Symptoms
- Leg Pain: Cramping or pain in the legs during physical activity (claudication).
- Numbness or Weakness: Loss of sensation or weakness in the legs.
- Non-Healing Sores: Slow-healing sores or wounds on the feet or legs.
- Coldness: Coldness in one leg compared to the other.
- Color Changes: Skin on the legs turning pale or bluish.
- Hair and Nail Changes: Diminished hair growth and slow nail growth on the affected limb.
Causes
- Atherosclerosis: The most common cause of PVD is atherosclerosis, where fatty deposits (plaque) build up in the arteries, narrowing and stiffening them over time.
- Diabetes: High blood sugar levels in diabetes can damage blood vessels and increase the risk of PVD.
- High Blood Pressure: Uncontrolled hypertension can lead to artery damage, contributing to PVD.
- Smoking: Tobacco use is a significant risk factor for PVD, as it damages blood vessels and accelerates atherosclerosis.
- High Cholesterol: Elevated levels of cholesterol can contribute to plaque buildup in the arteries.
- Age: The risk of PVD increases with age, particularly for those over 50.
- Family History: A family history of PVD may increase your susceptibility.
- Obesity: Excess weight puts added stress on the circulatory system and increases the risk of PVD.
- Inactivity: A sedentary lifestyle can contribute to obesity and increase PVD risk.
- Other Medical Conditions: Conditions such as kidney disease or inflammation of the blood vessels (vasculitis) can also be causes or contributors.
Complications of Peripheral Vascular Disease
Peripheral Vascular Disease (PVD) can have several significant consequences for those affected by it. Some of the key consequences include:
1. Reduced Blood Flow
PVD causes the narrowing or blockage of peripheral arteries, leading to decreased blood flow to the limbs. This reduced blood supply can result in pain, especially during physical activity, and can limit one’s ability to walk or engage in daily activities.
2. Claudication
Claudication is a common symptom of PVD, characterized by cramping, pain, or weakness in the legs during exercise or walking. The cramps usually come on after a predictably fixed distance (this varies between patients). It can severely impact one’s mobility and quality of life.
3. Non-Healing Wounds
Poor circulation due to PVD can slow down the body’s ability to heal. Minor cuts, sores, or ulcers on the legs and feet may take longer to heal and are at higher risk of infection.
4. Critical Limb Ischemia
In severe cases, PVD can lead to critical limb ischemia, a condition where there is a severe lack of blood flow to the limbs. This can result in tissue damage, gangrene, and even limb amputation if left untreated.
5. Cardiovascular Complications
PVD is often associated with a higher risk of heart disease and stroke. The same processes that cause blockages in peripheral arteries can also affect the coronary arteries and carotid arteries, increasing the risk of heart attacks and strokes.
6. Diminished Quality of Life
Living with the pain, reduced mobility, and the threat of limb loss can significantly impact a person’s overall quality of life. It can limit their ability to perform daily tasks, enjoy physical activities, and maintain independence.
7. Psychological Impact
PVD can also have psychological consequences, leading to anxiety, depression, or a reduced sense of well-being due to the challenges it presents.
Diagnosis
- Physical Examination: Dr. Lim will conduct a physical exam and assess your medical history.
- Ankle-Brachial Index (ABI): A simple, painless test to measure blood pressure in your arms and ankles.
- Ultrasound: Duplex ultrasound imaging to visualize blood flow in the arteries.
- Angiography: X-ray imaging with contrast dye to identify blockages.
- CT Scan: Advanced imaging techniques to assess blood vessel health. Required in select cases when there is suspicion of more proximal disease of the arteries in the abdomen.
Treatment Options
- Lifestyle Changes: Smoking cessation, adoption of a healthy diet, regular exercise.
- Medications: Prescribed to manage blood pressure, cholesterol, and prevent blood clot formation (antiplatelet medication e.g. aspirin).
- Angioplasty and Stenting: Minimally invasive procedures to open narrowed arteries. This is the mainstay modality of contemporary revascularization.
- Bypass Surgery: Surgical creation of a new path for blood flow around blocked arteries.
- Clot-Busting (Thrombolytic Medications): Administered in certain cases to dissolve blood clots.
Conclusion
Early diagnosis and appropriate management of PVD is crucial to prevent the onset of complications. Lifestyle changes, medication, minimally invasive procedures, or surgery may be recommended depending on the severity of the condition. Patients with PVD should work closely with vascular surgeons to develop a personalized treatment plan to improve their vascular health and reduce the risk of complications.

FAQ about Peripheral Vascular Disease
Peripheral Vascular Disease (PVD) is a blood circulation disorder, where blood vessels outside the heart—usually the arteries—experience narrowing or blockage, often affecting the legs and feet. This typically occurs due to atherosclerosis, a build-up of fatty deposits (plaque) on the vessel walls, leading to reduced or obstructed blood flow.
Anyone can develop PVD, but it’s more common in people over 50, smokers, diabetics, and those with high blood pressure or high cholesterol. Early detection and treatment is the best way to slow down progression of the disease and reduce your chances of irreversible tissue loss.
If you’re experiencing leg pain while walking, numbness, or sores that aren’t healing, you might have PVD. But don’t worry – Dr. Lim is here to help diagnose and treat your condition, getting you back on your feet in no time!
To diagnose PVD, Dr. Lim might recommend a range of tests like an ultrasound, blood tests, or an angiogram. These are pretty straightforward and will help in crafting your treatment plan by identifying which blood vessels are blocked and how severe the blockage is.
Poorly healing wounds can be a sign of reduced blood flow due to PVD, especially in patients suffering from diabetes. Patients with diabetes also often have diminished sensation in their feet due to nerve damage (neuropathy), making them more likely to injure themselves. It’s crucial to get these issues checked by a professional as early as possible to reduce your chances of further issues like infection, gangrene and irreversible tissue loss.
While there’s no magic bullet to ‘cure’ PVD, it can be very manageable. Lifestyle changes, medication, or sometimes surgery can help control the symptoms and improve your quality of life.
If you have been recently diagnosed with PVD, do not be afraid. Dr. Lim will guide you through the best treatment options for your situation and help you gain control over your health and body.
Treatment plans depend on the severity of your symptoms, amount of tissue damage and the extent of infection (if any).
General treatment plans typical include lifestyle changes, medications to optimize the treatment underlying conditions, medications to improve blood flow, and sometimes procedures to open blocked vessels. Dr. Lim has a wealth of knowledge and experience with complex angioplasties to help you and your loved ones obtain the best possible outcomes.
Dr Lim works closely with other doctors and allied health professionals, like endocrinologists, renal physicians, podiatrists and physiotherapists, to help his patients get back on their feet as soon as possible. Sometimes it may also be necessary for patients to speak to a dietician or nutritionist to help design a sustainable meal plan.
It can be frightening to hear the word “amputation,” but there may be options like revascularization procedures to improve blood flow and promote healing. Dr. Lim specializes in these life- and limb-saving techniques and will explore every possibility to help you. Remember that early treatment for infections or tissue damage is usually your best chance of avoiding irreversible tissue loss and seek medical advice as soon as possible.
It’s tough when loved ones avoid medical advice. In our experience, one of the best ways to help a loved one who refuses to seek medical treatment is to understand their personal barriers to seeking care. This conversation may be difficult to initiate as your loved one may be worried about having their views ridiculed or dismissed. Take their concerns seriously and show them that you understand and are hearing them. You can also take some time to understand their diagnosis to the best of your ability, in case they do not understand it and need it to be explained to them again.
Some reasons patients may avoid medical advice or treatment are 1) Fear of bad news, 2) Poor understanding of the disease or diagnosis, and, 3) Worries about being a ‘burden’ to their family (financially, physically etc.).
A lower limb angioplasty is a procedure to open up narrowed or blocked blood vessels in your legs, improving blood flow. It can relieve pain and help heal wounds. This is a minimally invasive procedure that requires a ‘puncture’ (injection) in your groin. Dr. Lim has successfully performed many of these procedures, helping patients regain their mobility and quality of life.
