Report of extracranial venous stenoses in relapsing-remitting multiple sclerosis patients.

摘要

Yamout et al.'s paper1 is welcomed by many people with multiple sclerosis (pwMS), as it reports that people with relapsing-remitting MS (RRMS) for more than 10 years are highly likely (12 of 13 subjects or 92%) to have extracranial venous stenoses (EVSs). This study made an error in combining results from RRMS and clinically isolated syndrome (CIS) subjects, naming them early MS (EMS). Such a grouping does not follow the McDonald criteria, as CIS is not MS in this classification. Excluding results for CIS from the data means results for a group of RRMS is obtained. This revised data shows that 18 RRMS subjects have stenosed veins within the subset of 31 subjects with RRMS. The resulting correlation factor of 0.58 is similar to the initial results from the Buffalo Neuroimaging Analysis Center (BNAC) Buffalo, NY, USA, which reported a correlation factor of 0.55.
