Peripheral vascular disease is a manifestation of systemic atherosclerosis that leads to significant narrowing of arteries distal to the arch of the aorta. The in the greatest degree common symptom of peripheral vascular disease is intermittent claudication. At other times, peripheral vascular disease leads to acute or critical limb ischemia. Intermittent claudication manifests as pain in the muscles of the leg with exercise; it is experienced from 2 percent of persons older than 65 years. Physical findings include abnormal pedal oscillations femoral artery bruit, delayed venous filling time, placid skin, and abnormal skin color. greatest in quantity patients present with subtle findings and lack classic symptoms, which makes the diagnosis difficult. The standard office-based exhibition to determine the presence of peripheral vascular disease is calculation of the ankle-brachial index. Magnetic resonance arteriography, duplex scanning, and hemodynamic localization are noninvasive [i]modus operandi[/i]s for lesion localization and may be helpful when symptoms or findings do not correlate with the ankle-brachial index. Contrast arteriography is used for definitive localization before intervention. Treatment is divided into lifestyle, medical, and surgical therapies. Lifestyle therapies focus onward exercise, smoking cessation, and dietary modification. Medical therapy is directed at reducing platelet aggregation. In addition, patients with contributing disorders as it is as hypertension, diabetes, and hyperlipidemia ne to have these conditions managed as aggressively as possible. Surgical therapies include s arterectomies, angioplasty, and bypass surgery

**********

Peripheral vascular disease (PVD) is the mien of systemic atherosclerosis in arteries distal to the arch of the aorta. As a proceed of the atherosclerotic process, patients with PVD expand narrowing of these arteries. The principally common symptom of PVD is intermittent claudication, which manifests as pain in the muscles of the leg with exercise and is experienced by the agency of 2 percent of persons older than 65 years. (1) In individual study of outpatients in the United States, PVD was instant in 29 percent of patients. (2) This inquiry included patients older than 70 and patients 50 to 69 years of age with a history of cigarette smoking or diabetes mellitus. The greatest modifiable risk factor for the disentanglement and progression of PVD is cigarette smoking. Cigarette smoking increases the not divisible by 2s for PVD by 1.4 for each 10 cigarettes smoked per day. (3)

Screening and Primary Prevention

To date, no studies have attempted to document reductions in morbidity and mortality that deduction from screening for PVD in primary care. The U Preventive Services Task Force has make acceptableed against routine screening for peripheral arterial disease. (4)

Primary prevention of PVD consists of encouraging smoking cessation. Smoking cessation also is make acceptableed for the prevention of coronary artery disease, chronic obstructive pulmonary disease, hit and lung cancer.

Diagnosis

The differential diagnosis of PVD includes musculoskeletal and neurologic causes. The mostly common entity that mimics PVD is spinal stenosis. Spinal stenosis can cause compression of the cauda equina, which follows in pain that radiates down the one and the other legs. The pain occurs with walking (i.e., pseudoclaudication) or protracted standing and does not subside rapidly with tranquillity Additional conditions to consider are acute embolism, knotty or superficial venous thrombosis, restles leg syndrome systemic vasculitides, nocturnal leg cramps, muscle or tendon strains, peripheral neuropathy, and arthritides (Table 1) (5)

Patients with PVD have a history of claudication, which manifests as cramp-like muscle pain occurring with exercise and subsiding rapidly with pause In addition, later in the course of the disease, patients may not absent with night pain, nonhealing sore s and skin color changes. However, PVD is asymptomatic in almost 90 percent of patients. (2) The Edinburgh Claudication Questionnaire has been shown to be 91 percent specific and 99 percent sensitive for diagnosing intermittent claudication in symptomatic patients. (6) It is compos of a series of six questions and a pain diagram that are self-administered by means of the patient (Table 2). (6)

Classic risk factors for PVD are smoking, diabetes mellitus, hypertension, and hyperlipidemia. novel trials have added chronic renal insufficiency, (7) elevated C-reactive protein flushs (8) and hyperhomocysteinemia (9) to the list of risk factors. In united series from the Netherlands, the likelihood of a patient having PVD (as defined on an anklebrachial index [ABI] of les than 09) was increased by means of being male (odds ratio [OR] 16); being older than 60 years (OR 41); having hypercholesterolemia (OR 19); having a history of ischemic heart disease (OR 35) cerebrovascular disease (OR 36) diabetes mellitus (OR 25) or intermittent claudication (OR 56); or smoking (OR 16) (9)

Physical examination findings in patients with PVD vary. They may include absent or diminished measured [i]or[/i] regular beats abnormal skin color, poor hair expansion and cool skin. The most numerous reliable physical findings are diminished or absent pedal pulsations presence of femoral artery bruit, abnormal skin color, and cold-blooded skin (Table 3 (10)), moreover their absence does not prevent PVD.
