After having found out an increase in the Von Willebrand Factor (vWF) and a relation between its persistance and seriousness of some vasculities, we looked for a link between changes in vWF level and hemorheology, their role and interdependence in the evolution of the vascular diseases, in complications and in relapses. We studied patients affected with degenerative and inflammatory vascular diseases and we determined rheologic parameters, in traditional and personal innovative way, pro- and anti-coagulation factors, other inflammatory proteins and hematic parameters. As regards coagulation only the vWF appeared increased in a significant way, without differences between two types of vascular diseases. As regards hemorheology, in both of them we measured an increase in the whole blood viscosity but with a different behaviour of its components. In the degenerative vascular diseases there was an increase both in corpuscular viscosity and in the plasma-erythrocyte one, a no significant increase in the plasma viscosity whereas the erythrocyte deformability was in the normal range. In vasculitis there was the highest increase in the plasma and corpuscular viscosities with a decrease in the deformability without changes in the plasma-erythrocyte viscosity. We give some interpretations on their different behaviour and a right meaning of the involved phenomena in every kind of rheologic parameter.
