Overview

Peripheral Artery Disease (PAD) is a circulatory condition in which narrowed or blocked arteries reduce blood flow to the legs and feet. The condition usually develops due to the buildup of fatty deposits (atherosclerosis) inside the arteries, making it difficult for oxygen-rich blood to reach the muscles and tissues. If left untreated, PAD can lead to persistent leg pain, poor wound healing, ulcers, and, in severe cases, tissue damage.

Early diagnosis and timely Peripheral Artery Disease treatment are essential to improve circulation, relieve symptoms, and prevent serious complications. Modern PAD treatment includes lifestyle modifications, medications, minimally invasive vascular procedures, and surgery, depending on the severity of artery blockage.

At Sarvodaya Hospital, our vascular surgeons, cardiologists, and multidisciplinary specialists provide advanced vascular disease care using state-of-the-art diagnostic technology and personalised treatment plans to restore healthy blood flow.

Symptoms of Peripheral Artery Disease

• Leg pain while walking (claudication)
• Leg cramps during exercise
• Numbness or weakness in the legs
• Coldness in one leg or foot
• Slow-healing wounds on the feet or legs
• Shiny skin on the legs
• Reduced hair growth on the legs
• Weak or absent pulses in the feet
• Pain at rest in advanced stages

Causes of Peripheral Artery Disease

• Atherosclerosis (fatty plaque buildup)
• Smoking
• Diabetes
• High blood pressure
• High cholesterol
• Obesity
• Chronic kidney disease
• Increasing age
• Family history of vascular disease

Risk Factors for PAD

Certain medical conditions and lifestyle habits significantly increase the risk of developing PAD.

• Smoking: Smoking damages blood vessels and is one of the strongest risk factors for peripheral artery disease.
• Diabetes: High blood sugar damages blood vessels and increases the risk of blocked leg arteries and poor circulation.
• High Cholesterol: Elevated cholesterol contributes to plaque formation inside arteries, restricting blood flow.
• High Blood Pressure: Long-term hypertension damages artery walls and accelerates atherosclerosis.

Diagnosis of Peripheral Artery Disease

Accurate diagnosis helps determine the severity of artery blockage and guides the most effective treatment approach.

• Clinical Examination: Doctors assess leg symptoms, skin changes, pulse strength, circulation, and overall vascular health.
• Ankle-Brachial Index (ABI): This simple, non-invasive test compares blood pressure in the arms and ankles to detect reduced blood flow.
• Doppler Ultrasound: Ultrasound evaluates blood flow through the arteries and identifies narrowed or blocked vessels.
• CT Angiography (CTA): CTA provides detailed images of blood vessels to assess the location and extent of artery blockage.
• MR Angiography (MRA): MRI-based angiography offers detailed vascular imaging without conventional catheterisation in selected patients.
• Digital Angiography: This advanced imaging procedure precisely identifies arterial blockages and helps plan minimally invasive treatment.

Treatment Options & Technology for Peripheral Artery Disease

Peripheral Artery Disease treatment aims to restore blood flow, relieve symptoms, prevent disease progression, and reduce cardiovascular complications.

• Lifestyle Modification: Stopping smoking, controlling diabetes, maintaining a healthy weight, and regular supervised exercise significantly improve circulation and overall vascular health.
• Medication Therapy: Medicines help reduce cholesterol, control blood pressure, prevent blood clots, and improve blood flow.
• Supervised Exercise Therapy: Structured walking programmes improve circulation, increase walking distance, and reduce leg pain caused by PAD.
• Endovascular PAD Treatment: Minimally invasive procedures such as balloon angioplasty and stent placement help open narrowed or blocked leg arteries.
• Peripheral Artery Bypass Surgery: In advanced disease, vascular bypass surgery creates an alternative route for blood flow around blocked arteries.
• Advanced Vascular Technology: Ankle-Brachial Index (ABI), Colour Doppler Ultrasound, CT Angiography, MR Angiography, Digital Angiography, and Intravascular Ultrasound (IVUS) support accurate diagnosis and personalised artery blockage treatment.

Benefits of Early Peripheral Artery Disease Treatment

Timely diagnosis and treatment significantly improve circulation and long-term vascular health.

• Improves Blood Flow: Early treatment restores circulation and reduces symptoms caused by blocked arteries.
• Reduces Leg Pain: Improved blood supply allows patients to walk longer distances with less discomfort.
• Prevents Disease Progression: Timely management reduces the risk of severe artery blockage and limb complications.
• Protects Limb Health: Restoring circulation promotes wound healing and lowers the risk of tissue damage.
• Reduces Cardiovascular Risk: Treating PAD also lowers the risk of heart attack and stroke associated with widespread atherosclerosis.

Complications if Left Untreated

Untreated peripheral artery disease can lead to serious health problems.

• Critical limb ischaemia
• Non-healing foot ulcers
• Tissue death (gangrene)
• Limb amputation
• Heart attack
• Stroke
• Severe disability

When Should You See a Doctor for Peripheral Artery Disease?

Consult a vascular specialist if you experience:

• Leg pain while walking
• Persistent leg cramps
• Cold feet or toes
• Slow-healing wounds
• Numbness in the legs
• Skin colour changes in the feet
• Pain in the legs at rest

Prevention & Lifestyle Modifications for Peripheral Artery Disease

Healthy habits play an important role in preventing PAD and slowing disease progression.

• Quit Smoking: Smoking cessation is the most effective way to reduce vascular disease progression.
• Exercise Regularly: Daily walking programmes improve circulation and strengthen leg muscles.
• Control Diabetes: Maintaining healthy blood sugar protects blood vessels from further damage.
• Follow a Heart-Healthy Diet: Eating foods low in saturated fats and rich in fruits, vegetables, and whole grains supports vascular health.
• Manage Blood Pressure and Cholesterol: Regular monitoring and prescribed treatment help reduce future artery blockage.
