Peripheral artery disease (PAD) is caused from the narrowing of damaged arteries most commonly affecting one or both of the legs. The classic symptoms of intermittent claudication is a predictable leg pain when walking for a certain distance, due to insufficient atrial circulation to supply an increased oxygen demand for the increased muscular exertion when walking. Pain then resolves with rest. Symptoms may also include skin ulceration, a cold skin temperature, pale or bluish skin tone, reduced or deformed toenails and reduced hair growth in the affected leg(s), with a reduced pulse in the affected limb. However, up to 50 percent of mild to moderate PAD cases do not produce obvious symptoms. Risk factors include anything that can damage the arterial circulation including cigarette smoking, diabetes, uncontrolled high blood pressure or blood cholesterol. PAD is diagnosed by determining the ankle-brachial index (ABI) which compares the systolic blood pressure at the ankle divided by the systolic blood pressure of the arm. Duplex ultrasound can also be used and an angiography may be done in anticipation of a surgical repair on narrowed segments of leg arteries (similar to a cardiac catheter and repair of coranary blockages).
