title: [Hemorrheological anomalies: an element of additional risk in arterial diseases].
abstract: Arterial blood flow to different tissues and organs is influenced by blood viscosity. The main determinants of blood viscosity are hematocrit and plasma protein concentration. Venesection and consequent reduction of hematocrit are very useful in various pathological conditions. Plasma-exchange removes proteins in excess (such as LDL in familial hypercholesterolemia) from plasma and thereby improves plasma viscosity, erythrocyte deformability and blood flow to the body tissues.
