Peripheral vascular disease (PVD) refers to the obstruction of large arteries not within the coronary, aortic arch vasculature, or brain. PVD can result from atherosclerosis, inflammatory processes leading to stenosis, an embolism, or thrombus formation.

It causes either acute or chronic ischemia (lack of blood supply). Often PAD is a term used to refer to atheresclortic blockages found in the lower extremity

Symptoms

About 20% of patients with mild PAD may be asymptomatic; other symptoms include:

• Claudication - pain, weakness, numbness, or cramping in muscles due to decreased blood flow
• Sores, wounds, or ulcers that heal slowly or not at all
• Noticeable change in color (blueness or paleness) or temperature (coolness) when compared to the other limb
• Diminished hair and nail growth on affected limb and digits.
