Peripheral vascular disease (PVD) is a general term for disease of any blood vessel that is not part of the heart or brain. The arterial form, usually referred to as PAD, is caused by deposits of fatty material (atheroma) in arteries of the legs. Since arteries carry oxygen-rich blood to the cells of the body, restriction of this blood flow can cause bodily organs to fail.
This is a potentially serious condition that requires care from your doctor. The sooner PAD is treated, the more favorable the outcome. If you suspect you have this condition, contact your doctor.
PAD is usually caused by a gradual buildup of plaque within the arteries ( atherosclerosis ). Other causes include blood clots or embolisms, congenital heart disease, and inflammation of the blood vessels (vasculitis).
PAD can be hereditary. More commonly, you may get PAD if you are overweight or obese , or have high blood pressure , diabetes , or high cholesterol . Unhealthy lifestyle choices such as smoking, eating a high-fat diet, and not exercising enough frequently lead to PAD.
The following factors increase your chance of developing PAD. If you have any of these risk factors, discuss them with your doctor:
Symptoms of PAD are related to the organ or part of the body deprived of adequate circulation. This includes:
Your doctor will ask about your symptoms and medical history, and perform a physical exam . Tests may include the following:
Early treatment can slow or stop the advancement of the disease. Talk with your doctor about the best treatment plan for you. Treatment options include the following:
Surgery to open up narrowed arteries is performed in severe cases.
If you are diagnosed with PAD, follow your doctor's instructions .
