Peripheral Artery Disease

What Is Peripheral Artery Disease (PAD)? 

Peripheral artery disease occurs when arteries in the limbs—most often the legs—become narrowed or obstructed due to plaque accumulation. This restricts blood circulation, which can result in discomfort, delayed wound healing and other complications. 

PAD primarily impacts the lower extremities and may indicate broader cardiovascular issues.

Typical Signs and Symptoms

PAD can present in various ways, including: 

  • Aching or cramping in the legs during activity (known as claudication) 
  • Tingling, numbness or leg weakness 
  • A feeling of cold in the foot or lower leg 
  • Persistent sores or ulcers that are slow to heal 
  • Reduced hair or toenail growth 

Some individuals may not notice any symptoms, especially in early stages. 

Diagnostic Methods

To identify PAD, healthcare professionals may perform: 

  • Ankle-Brachial Index (ABI): Measures blood pressure differences between the arms and legs 
  • Doppler Ultrasound: Assesses blood flow in the arteries 
  • Lab Tests: Evaluate for contributing health conditions 
  • Angiography: Provides detailed imaging of arterial blockages 

Timely diagnosis is essential to avoid serious health issues. 

Treatment and Management Strategies

Managing PAD often involves a combination of approaches: 

  • Lifestyle Adjustments: Regular walking, smoking cessation and a heart-healthy diet 
  • Medications: Help improve circulation and reduce the risk of blood clots 
  • Interventional Procedures: Techniques like angioplasty or stent placement to reopen narrowed arteries 
  • Proper treatment can enhance mobility and support overall cardiovascular health.
