Peripheral Artery Disease
Peripheral artery disease (PAD) is a condition in which plaque buildup inside the arteries reduces blood flow to the arms or legs, most commonly the legs. PAD is caused by atherosclerosis, a process where cholesterol, fat, and other substances accumulate within the artery walls, causing narrowing or blockage of blood vessels.
Reduced blood flow can lead to pain, difficulty walking, poor wound healing, and an increased risk of cardiovascular complications such as heart attack and stroke.
SYMPTOMS
of Peripheral Arterial Disease (PAD)
Some people with PAD may not experience symptoms, especially in the early stages. When symptoms occur, they may include:
Leg pain while walking (claudication)
Cramping or aching in the calves, thighs, hips, or buttocks during activity
Leg pain that improves with rest
Coldness in the lower leg or foot
Numbness or weakness in the legs
Weak or absent pulses in the feet or legs
Pain in the arms with activity
Shiny skin on the legs
Slower hair or toenail growth
Skin discoloration
Sores or wounds on the feet or legs that heal slowly or not at all
In more advanced PAD, pain may occur even at rest or during sleep.
DIAGNOSIS
of Peripheral Artery Disease
Peripheral artery disease is diagnosed through a combination of physical examination, medical history, and vascular testing.
Diagnostic testing may include:
Blood tests to evaluate cholesterol, blood sugar, and cardiovascular risk factors
Ankle-brachial index (ABI)
Doppler ultrasound or vascular ultrasound
Angiography
These tests help determine the location and severity of arterial narrowing or blockage.
TREATMENT
for Peripheral Artery Disease
Treatment for PAD focuses on improving blood flow, reducing symptoms, preventing disease progression, and lowering the risk of heart attack and stroke.
Lifestyle Changes
Lifestyle modifications are often the first step in treatment and may include:
Quitting smoking or tobacco use
Regular walking and exercise programs
Eating a heart-healthy diet
Managing blood pressure, cholesterol, and diabetes
Maintaining a healthy weight
Medications
Medications may be prescribed to:
Lower cholesterol
Control blood pressure
Manage diabetes
Reduce the risk of blood clots
Improve walking distance and leg symptoms
Procedures
If symptoms are severe or blood flow is significantly reduced, minimally invasive procedures or surgery may be recommended.
Common Procedures Include:
Angioplasty with or without stent placement
During angioplasty, a small balloon is used to widen the narrowed artery and improve circulation. In some cases, a stent may be placed to help keep the artery open.
Early diagnosis and treatment of PAD can help improve quality of life, preserve circulation, and reduce the risk of serious cardiovascular complications.
