Expert Care for Peripheral Artery Disease in Bronx, NY

What is Peripheral Artery Disease?

Peripheral artery disease (PAD) is a common circulatory problem in which narrowed or blocked arteries reduce blood flow to the limbs, most often the legs. This restricted blood flow can cause pain, cramping, and weakness, especially during walking or physical activity. PAD is not just a condition of the legs , it is also a warning sign of widespread vascular disease, meaning patients with PAD are at higher risk of heart attack and stroke.

Symptoms of Peripheral Artery Disease

PAD symptoms can develop gradually and often worsen over time. Some people may have mild or no symptoms, while others experience significant discomfort that affects daily activities. Common signs include:

• Leg pain or cramping: Often triggered by walking or exercise (claudication) and relieved by rest.
• Numbness or weakness: Affected legs may feel weak, heavy, or fatigued.
• Coldness in lower leg or foot: Compared to the other side.
• Sores or wounds that heal poorly: Especially on the toes, feet, or legs.
• Change in skin color: Shiny skin or slower hair and toenail growth.
• Rest pain: Severe PAD may cause leg pain even while at rest or when lying down.

Causes and Risk Factors

Peripheral artery disease develops when fatty deposits (plaques) build up in the artery walls, a process known as atherosclerosis. This narrowing limits blood flow and oxygen delivery to the muscles. Factors that increase the likelihood of developing PAD include:

• Smoking: The most significant risk factor for PAD.
• Diabetes: High blood sugar damages blood vessels and accelerates plaque buildup.
• High blood pressure: Increases strain on arteries and promotes narrowing.
• High cholesterol: Contributes to fatty deposits in artery walls.
• Age: Risk rises significantly after age 50, especially with other risk factors.
• Obesity and sedentary lifestyle: Lack of activity can worsen circulation and vascular health.
• Family history: A close relative with PAD, heart disease, or stroke raises the risk.
  
  

  Treatment for PAD aims to relieve symptoms, improve quality of life, and reduce the risk of complications. 

  Depending on the severity of the condition, treatment options may include:

  1. Lifestyle modifications: Quitting smoking, adopting a healthy diet low in saturated fats and cholesterol, regular exercise, and maintaining a healthy weight can help manage PAD and improve overall cardiovascular health.
  2. Medications: Your doctor may prescribe medications to manage symptoms and reduce the risk of complications, such as blood thinners (anticoagulants), antiplatelet drugs, cholesterol-lowering medications (statins), and medications to control blood pressure and blood sugar levels.
  3. Angioplasty, Atherectomy and stenting: In more severe cases of PAD, procedures such as angioplasty, atherectomy and stenting may be performed to open blocked or narrowed arteries. During angioplasty, a catheter with a balloon tip is inserted into the narrowed artery and inflated to widen the artery and improve blood flow. Atherectomy procedure involves removing plaque buildup from the artery using a specialized catheter with cutting or grinding tools. Stenting involves placing a small metal mesh tube (stent) in the artery to keep it open.
  4. Bypass surgery: In cases where angioplasty, stenting, or atherectomy are not suitable or effective, bypass surgery may be recommended. This involves creating a new pathway for blood flow by grafting a healthy blood vessel from another part of the body or using a synthetic graft to bypass the blocked or narrowed artery.
