Chronic
cerebrospinal venous insufficiency (CCSVI) is a vascular picture in multiple
sclerosis patients characterized by stenoses affecting the main extracranial
venous outflow pathways and by a high rate of cerebral venous reflux that may
lead to increased iron deposition in the brain. We explored relationship
between venous hemodynamic (VH) parameters and disability and iron
concentration in deep-gray matter (DGM) structures and lesions on
susceptibility-weighted imaging. There was a significant association between
higher number of VH criteria and higher iron concentration in T2 and T1
lesion volumes. Higher iron concentration in DGM structures was strongly
associated with higher disability status.
