Abstract:
Objective. To evaluate the jugular veins (IJV) using duplex sonography in patients with multiple sclerosis (MS). Material and methods. The study included 21 MS patients with different disease course, degree of disability and disease duration. A control group consisted of 8 healthy volunteers. Results. IJV changes that meet the CCSVI criteria have not been found. These findings are consistent with the results of recently published large studies. Possible reasons of non-confirmation of this hypothesis are discussed. Conclusion. Currently vascular intervention in MS is not recommended.
