Hospital Discharge Teaching for Patients with Peripheral Vascular Disease.

Peripheral disease affects both arteries and veins and encompasses pathophysiologic conditions that affect arterial, venous, and lymphatic circulations. This article discusses disorders of peripheral vascular disease (PVD) that affect the lower extremity. PVD is an obstruction in the arteries known as arteriosclerosis obliterans, a condition that manifests from insufficient tissue perfusion that results in hardening of the arteries. Peripheral artery disease leads to an inflammatory condition called atherosclerosis. People at greatest risk include smokers, diabetics, those with high blood pressure, and those with elevated cholesterol levels.
