Hemodynamic Aspects of Chronic Venous Disease
The hemodynamics of chronic venous disease differs significantly from arterial insufficiency. Often, arterial concepts are inappropriately applied to venous pathology. In some instances, such as, for example, saphenous reflux, applicable hemodynamics is unique and has no parallel in arterial practice. In this chapter, we focus on four areas of chronic venous disease: (1) quantifying saphenous reflux, (2) defining critical venous stenosis, (3) grading severity of iliac vein stenosis (“area method”), and (4) hemodynamics of venous collaterals and venous bypass.
