Peripheral vascular disease, abbreviated as PVD, is a condition characterized by obstruction of large arteries, causing the blood supply to reduce significantly. Such a type of condition is also referred to as Peripheral arterial disease.
Presentation
Intermittent claudication, characterized by pain in leg, experienced while walking, is the classical symptom of peripheral vascular disease. In addition to pain, affected individuals would also experience cramps, weakness and numbness in the area of reduced blood flow [7].
Other symptoms of PVD include the following:
- Development of sores and ulcers in the affected area which do not heal easily
- There is no nail or hair growth in the affected limb
- There is change in the color characterized by bluish tinge or paleness
- Temperature changes also occur; wherein one limb is cold to touch, in comparison to other – a condition known as unilateral dependent rubor.
Entire Body System
- Asymptomatic
Two carotid lesions at follow up were asymptomatic without stroke. CONCLUSION: Endovascular treatment of peripheral vascular lesions, i.e., aortoiliac, femoropopliteal tibioperoneal and carotid lesions were satisfactory in immediate outcome. [ncbi.nlm.nih.gov]
Risk factors The risk factors for PAD are basically the same as for coronary artery disease : diabetes mellitus cigarette smoking advancing age hypercholesterolemia hypertension overweight/ obesity Rutherford classification stage 0: asymptomatic stage [radiopaedia.org]
Most patients are asymptomatic, but many experience intermittent claudication (pain on walking). [bmj.com]
- Congestive Heart Failure
Despite the absence of symptoms and signs of congestive heart failure at presentation, AAS-induced cardiomyopathy with a thrombus in the left ventricle was discovered to be the aetiology of his stroke and peripheral vascular disease. [ncbi.nlm.nih.gov]
Clinical findings: Most children with PDA do not have heart related symptoms. If the ductus is large in size, symptoms of congestive heart failure may develop. [mottchildren.org]

- Difficulty Walking
If that blockage remains in the peripheral arteries of the legs, it can cause pain, changes in skin color, difficulty walking and sores or ulcers. Total loss of circulation to the legs and feet can cause gangrene and the loss of a limb. [heart.org]
Get active: Regular exercise, such as walking, can often reduce symptoms and increase the distance you can walk without symptoms. Eat nutritious, low-fat foods and avoid foods high in cholesterol. Maintain a healthy weight. [webmd.com]
- Toe Pain
When PAD becomes severe, you may have: Impotence Pain and cramps at night Pain or tingling in the feet or toes, which can be so severe that even the weight of clothes or bed sheets is painful Pain that is worse when you elevate your legs, and improves [medlineplus.gov]

Neurologic
- Burning Sensation
It is an aching or burning sensation in the muscles of the leg that it reliably reproduced after a set walking distance and is relieved with rest. It is not exacerbated by position or present at rest. [physio-pedia.com]
- Agitation
Contrast echocardiography may be helpful in this setting; intravenous injection of agitated saline leads to microbubbles in the descending aorta (from ductal right-to-left shunting) but not in the ascending aorta. [ahajournals.org]
Workup
The following tests are used for diagnosis of PVD:
- Physical examination: Preliminary physical examination to detect weak pulse, whooshing sound, and signs of poor wound healing in the affected area, would be determined.
- ABI – Ankle Brachial Index: This is one of the most common tests for diagnosing PVD. It measures the blood pressure in the ankle, as well as in the arm. Individuals will be asked to walk on a treadmill, to measure the severity of the symptoms, before and after the exercise [8].
- Ultrasound examination: This method can help evaluate the blood flow, as well as aid in identification of narrowed arteries.
- Blood tests: This is done to determine the presence of underlying conditions, such as diabetes and levels of triglycerides and cholesterol.
- Angiography: Such a type of test, allows in identifying the blocked arteries, and degree of blockage as well.
Treatment
Treatment of PVD depends on severity of the condition: The following methods would be employed:
- Medications: Medications, such as cilostazol and pentoxifylline, are administered for providing relief from claudication. In addition, medications to lower blood pressure, diabetes and cholesterol are also given.
- Lifestyle modifications: Individuals are also suggested to avoid smoking, alcohol, calorie dense foods, and sedentary lifestyle. All these, significantly increase the chances of developing PVD, and therefore, should be avoided [9].
- Angioplasty: This is a method, which helps in opening the clogged arteries. It is the same procedure, which is employed for opening blocked arteries of the heart.
- Surgery: It is the method of choice, when all other treatments do not bring about the desirable effect. It is known as bypass surgery, wherein a graft bypass is created, with the help of neighboring blood vessels. In some cases, synthetic blood vessels may also be used [10].
Prognosis
Prognosis of peripheral vascular disease depends on the severity of the condition. This is measured with the help of a tool, named as the Ankle brachial pressure index [6]. Individuals with PVD are at an increased risk of developing cardiovascular events, and subsequent mortality. However, if the disease is diagnosed in the preliminary stages, then adopting certain measures can effectively help in controlling the condition.
Etiology
Development of atherosclerosis is the primary cause of PVD. Although, atherosclerosis majorly affects the heart functioning; it can also significantly affect the blood supply to the limbs, giving rise to PVD. Along with atherosclerosis, other causative factors, such as diabetes mellitus, hypertension, dyslipidemia and obesity, also predispose an individual to develop peripheral vascular disease.
In addition, other risk factors for PVD include emotional stress, extreme cold temperatures, smoking, and operating vibrating tools and machinery [2].
Epidemiology
Peripheral vascular disease affects about 10 – 12% of general population. Individuals, above 70 years of age, are more prone to contract this disease condition. It has been estimated that, 20% of individuals at this age develop PVD. It has also been reported that, 1 in every 3 diabetic individuals contract PVD [3].
In the US, PVD strikes about 10 million Americans. In spite of high prevalence rates and associated complications, only 25% of individuals affected by PVD seek medical intervention.
Pathophysiology
The basic principle involved in the development of peripheral vascular disease, is the narrowing of the arteries, which causes significant reduction in the blood supply to the extremities. Such a kind of phenomenon occurs as a result of several predisposing factors, which include atherosclerosis, smoking, hypertension and diabetes.
It has been reported that, individuals who smoke, are 2 – 3 times at increased risk of developing peripheral arterial disease, concerning the lower extremities. Certain statistics also point towards the fact that, diabetes alone was the major cause of limb amputation in about 70% of cases [4, 5].
Prevention
Maintaining a healthy lifestyle is the key to prevent development of PVD. The following measures can be adopted, to stay healthy, and keep PVD at bay [11]:
Summary
It is a type of circulation disorder, gravely affecting the blood vessels, not including the heart and brain. PVD can turn into a life threatening condition, which can lead to amputation of the affected limb. In more severe conditions, it can also cause death of the individual. Disease conditions, such as atherosclerosis, embolism, stenosis and thrombus formation, can increase the risk of development of PVD [1].
Patient Information
- Definition: Peripheral vascular disease is a condition, characterized by narrowing of the arteries, which causes intermittent claudication to set in. Individuals with underlying disease conditions, and elderly population, are at an increased risk of developing this condition.
- Cause: Atherosclerosis is the major cause of PVD. In addition, several other factors, such as hypertension, diabetes, smoking, obesity and dyslipidemia, increase the chances of contracting PVD.
- Symptoms: Symptoms of PVD include intermittent claudication, characterized by pain in leg during walking. Other symptoms include changes in the coloration, and temperature of the affected skin, followed by development of sores, and ulcers which do not heal readily.
- Diagnosis: Diagnosis is done, through the ankle brachial pressure index, in addition to ultrasound and angiography. Blood tests are also done to determine the underlying disease conditions.
- Treatment: Lifestyle changes and medications form the basis of the treatment regime. Medications to relieve symptoms, and manage the underlying conditions are given. Moreover, leading a healthy lifestyle with regular exercise and healthy diet is also essential.
