Endothelin-1 concentrations in the internal jugular and azygous veins in multiple sclerosis patients: the results of a pilot study

2014

Objectives: In this pilot study we examined the potent vasoconstrictor, endothelin-1, in the blood of multiple sclerosis patients in the context of chronic cerebrospinal venous insufficiency hypothesis. For this purpose we measured endothelin-1 concentrations in blood samples that were obtained during selective catheterisation of the main veins draining the central nervous system: the internal jugular veins and the azygous vein. Material and methods: We measured endothelin-1 concentrations in peripheral blood in nine multiple sclerosis patients and five healthy controls. In multiple sclerosis patients this peptide was also evaluated in blood samples obtained from the internal jugular veins …
