Peripheral Circulation and Vascular Disorders

Peripheral circulation and vascular disorder primarily result in increased blood flow to the extremities.

Arterial disorders can cause tissue necrosis due to chronically progressive pathologic changes to the arterial vasculature.

Arteriosclerosis is a diffuse process that thickens the muscle fibers and the endothelial lining of the walls of small arteries and arterioles.

Circulatory insufficiency of the extremities always leads to edema and skin changes.

The regulatory mechanism of peripheral vessels is solely dependent on the central nervous system influences.

Varicose veins are caused by incompetent venous valves and most commonly occur in the lower extremities

Atherosclerosis affects the intima of large and medium-sized veins

Peripheral arterial insufficiency may cause chronic, continuous, and disabling pain

Bed rest is encouraged for patients with varicose veins after ligation and stripping surgery

Atherosclerosis involves the accumulation of lipids, calcium, blood components, carbohydrates, and fibrous tissue on the intimal layer of the artery
