PY - 2024 T2 - Vascular and Endovascular Surgery: Clinical Diagnosis and Management AB - Hemodynamic principles describe how blood flows in arteries and veins. This includes the relationship between pressure, flow, and resistance in normal, diseased, and collateral vessels. The clinical significance of arterial disease such as obstruction depends on its location, severity, and duration, as well as on the ability of the circulation to compensate, by changing cardiac output and developing collateral pathways. The aim of this chapter is to describe the principles and laws that are essential to understanding the pathophysiology and the fundamentals of the treatment of vascular disease. There are a few principles that govern flow in tubes including blood vessels; however, blood vessels are more compliant than rigid tubes making blood vessels more complex than rigid tubes. Additionally, blood vessels are affected by biological and hormonal factors that add to the complexity of the flow in blood vessels.
