Peripheral vascular disease (PVD) is a slow and progressive circulation disorder caused by narrowing, blockage, or spasms in a blood vessel. It is a common condition, affecting around 8.5 million people in the United States, and can lead to reduced blood flow to the limbs, most often the legs. The most common symptom of PVD is pain, which becomes worse as circulation becomes more limited. This pain is caused by a lack of oxygen reaching the leg muscles. While the pain typically occurs during physical activity, it can persist even while resting as the condition progresses.

What You'll Learn
Peripheral vascular disease (PVD) is a circulation disorder
Peripheral vascular disease (PVD) is a slow and progressive circulation disorder caused by narrowing, blockage, or spasms in a blood vessel. It is a type of systemic disorder that involves the narrowing of peripheral blood vessels, or vessels situated away from the heart or brain. This happens due to the buildup of plaque, known as arteriosclerosis or atherosclerosis. The legs and feet are the most commonly affected body parts, but PVD may affect any blood vessel outside of the heart, including the arteries, veins, or lymphatic vessels.
The reduced blood flow to the limbs caused by PVD can result in pain and discomfort while walking. This pain tends to worsen as circulation becomes more limited. Other symptoms include cramping, achiness, burning, and fatigue. If left untreated, PVD can progress into critical limb ischemia, a severe stage that may result in the loss of the affected limb. However, if caught early, PVD is treatable and reversible.
The diagnosis of PVD is typically based on patient risk factors, clinical presentation, and physical exam findings. A handheld ultrasound device can be used to obtain an accurate picture of abnormalities in the vessels or obstructions of blood flow. MRI is another noninvasive imaging technique that provides detailed images of blood vessels.
The main goals of PVD treatment are to control symptoms and halt disease progression, thereby lowering the risk of heart attack, stroke, and other problems. Treatment options include lifestyle changes, such as regular exercise, good nutrition, and smoking cessation, as well as medications and vascular surgery.
While PVD does not directly cause muscle pain, the reduced blood flow associated with the condition can lead to pain, discomfort, and other symptoms, particularly in the legs and feet.

PVD is caused by blockage, narrowing or spasms in blood vessels
Peripheral vascular disease (PVD) is a slow and progressive circulation disorder caused by narrowing, blockage, or spasms in a blood vessel. It is a disease or disorder of the circulatory system outside of the brain and heart, including DVT and PE. PVD may affect any blood vessel outside of the heart, including the arteries, veins, or lymphatic vessels. Organs supplied by these vessels, such as the brain or legs, may not get enough blood flow for healthy function.
The most common cause of PVD is atherosclerosis, or the buildup of plaque—a mix of fat, cholesterol, and other substances—inside your artery walls. The plaque builds up enough to narrow a peripheral artery and reduce blood flow, which can lead to symptoms of PVD such as pain, skin colour changes, trouble walking, and sores. When an artery is blocked or narrowed, the part of the body it supplies doesn't get enough oxygen. This condition is called ischemia, which can cause symptoms such as pain, cold feet, and bluish discolouration. Ischemia can also lead to more severe complications such as stroke or gangrene.
PVD can also be caused by blood clots, which may form on the artery walls, further reducing blood flow. In addition to atherosclerosis and blood clots, infections and injuries can also cause PVD. Specifically, salmonellosis (infection with Salmonella bacteria) and syphilis can damage blood vessels, and accidents such as car collisions or bad falls can injure blood vessels.
The treatment for PVD aims to control symptoms and halt the progression of the disease to lower the risk of heart attack, stroke, and other problems. Lifestyle changes, such as regular exercise, a healthy diet, and smoking cessation, can help control risk factors. Additionally, medications such as antiplatelet medicines (blood thinners) and vascular surgery may be recommended to improve blood flow and restore circulation.

PVD can cause muscle pain and fatigue
Peripheral vascular disease (PVD) is a slow and progressive circulation disorder caused by narrowing, blockage, or spasms in a blood vessel. PVD may affect any blood vessel outside of the heart, including the arteries, veins, or lymphatic vessels. Organs supplied by these vessels, such as the brain or legs, may not get enough blood flow for healthy function. The legs and feet are most often affected, and the most common symptom is pain, which becomes worse as circulation becomes more limited.
The pain and fatigue associated with PVD can interfere with daily activities and impact a person's quality of life. It is important to seek medical advice if experiencing any symptoms of PVD. Early intervention can help prevent the condition from progressing and reduce the risk of severe complications. Treatment options for PVD include lifestyle modifications, medications, and surgical procedures.
Lifestyle changes that may help manage PVD include regular exercise, a healthy diet, and smoking cessation. Exercise, in particular, can improve blood flow and reduce symptoms. However, it is important to consult a healthcare provider before starting an exercise routine to ensure it is safe and appropriate for your condition. Additionally, medications such as antiplatelet drugs and vascular surgery may be recommended to improve blood flow and alleviate symptoms of PVD, including muscle pain and fatigue.

Treatment options include medication and lifestyle changes
Peripheral vascular disease (PVD) is a slow and progressive circulation disorder caused by narrowing, blockage, or spasms in a blood vessel. It is a common condition, affecting about 8.5 million people in the United States, and is more prevalent in those over 60 years of age. The legs and feet are the most frequently affected body parts, but PVD may impact any blood vessel outside of the heart, including the arms and kidneys.
The main goals of PVD treatment are to manage symptoms and prevent the disease from progressing further. This is crucial to lower the risk of heart attack, stroke, and other complications. Treatment options include medication and lifestyle changes.
Medications used to treat PVD include:
- Antiplatelet medicines (blood thinners) to prevent blood cells and platelets from clumping together and forming clots, thereby improving blood flow. Examples include aspirin, aspirin plus dipyridamole, ticlopidine, and clopidogrel.
- Medicines that relax the blood vessel walls, such as Cilostazol (Pletal), which helps dilate or expand the blood vessels, encouraging improved blood flow.
- Drugs to lower blood pressure, lower cholesterol, and optimize blood sugar if you have diabetes.
Lifestyle changes that can help manage PVD include:
- Regular exercise
- Good nutrition, including a diet low in fat, cholesterol, and simple carbohydrates, and high in fruits, vegetables, low-fat dairy, and lean meats
- Not smoking, including avoiding secondhand smoke and tobacco products
- Aggressively treating other problems that may worsen PVD, such as diabetes, high blood pressure, and high cholesterol
In more severe cases of PVD, vascular surgery may be required to restore blood flow. This could involve a bypass graft using a blood vessel from another part of the body or a synthetic tube to reroute blood flow, or angioplasty, where a catheter (thin, flexible tube) is inserted to create a larger opening in the blocked artery.

PVD can lead to severe complications if left untreated
Peripheral vascular disease (PVD) is a slow and progressive disorder of the blood vessels caused by narrowing, blockage, or spasms in a blood vessel. It is a type of circulatory system disease outside of the brain and heart. PVD can lead to severe complications if left untreated.
Complications of untreated PVD occur due to decreased or absent blood flow, which can result in permanent numbness, tingling, or weakness in the legs or feet. This can also lead to a constant burning or aching pain in the affected areas. One of the most severe complications is gangrene, which occurs when the affected limb does not receive sufficient blood flow, leading to tissue death.
PVD can also progress into critical limb ischemia, a severe stage that may result in the loss of the affected limb. This condition is characterised by insufficient blood flow to the limbs, causing symptoms such as pain, cold feet, and bluish discolouration. If not addressed, the affected limb may suffer permanent damage.
Additionally, untreated PVD increases the risk of heart attack and stroke. This is because PVD can be associated with other conditions such as coronary artery disease (CAD) and diabetes, which are risk factors for cardiovascular events. Therefore, it is crucial to manage PVD through lifestyle changes, such as regular exercise, a healthy diet, and smoking cessation, as well as medical treatments to prevent these severe complications.
While PVD can lead to severe complications, early detection and treatment can often result in a full recovery. It is important to consult a healthcare professional if any symptoms of PVD are present or if there is a family history of the disease.
