Study Notes
Peripheral Circulation and Vascular Disorders
- Increased blood flow to extremities is primarily due to peripheral circulation and vascular disorders.
- Arterial disorders can lead to tissue necrosis through progressive pathological changes in the arterial vasculature.
Arteriosclerosis
- Characterized by thickening of muscle fibers and endothelial lining in small arteries and arterioles.
- Affects blood flow and can result in circulatory insufficiency.
Circulatory Insufficiency
- Always leads to edema and changes in skin integrity.
- Impacts extremity health significantly.
Regulatory Mechanism
- Peripheral vessel regulation is influenced exclusively by the central nervous system.
Varicose Veins
- Caused by incompetent venous valves, primarily affecting lower extremities.
- Post-operative care for varicose vein ligation and stripping surgery includes encouragement of bed rest.
Atherosclerosis
- Affects the intima of large and medium-sized arteries.
- Involves lipid, calcium, blood components, carbohydrates, and fibrous tissue accumulation on the arterial intimal layer.
- Can lead to peripheral arterial insufficiency, resulting in chronic, continuous, disabling pain.
