peripheral vascular disease (PVD),

any abnormal condition that affects the blood vessels and lymphatic vessels, except those that supply the heart. Different kinds and degrees of PVD are characterized by a variety of signs and symptoms, such as numbness, pain, pallor, elevated blood pressure, and impaired arterial pulsations. Causative factors include obesity, cigarette smoking, stress, sedentary occupations, and numerous metabolic disorders. PVD in association with bacterial endocarditis may involve emboli in terminal arterioles and produce gangrenous infarctions of distal parts of the body, such as the tip of the nose, the pinna of the ear, the fingers, and the toes. Large emboli may occlude peripheral vessels and cause atherosclerotic occlusive disease. Treatment of severe cases may require amputation of gangrenous body parts. Less severe peripheral vascular problems may be treated by eliminating causative factors, especially cigarette smoking, and by administering various drugs, such as salicylates and anticoagulants. Some kinds of peripheral vascular disease are atherosclerosis and arteriosclerosis.
