AIM: Chronic cerebrospinal venous insufficiency (CCSVI) is associated with multiple sclerosis (MS). CCSVI is detected by transcranial and extracranial color-Doppler high-resolution examination (TCCS-ECD) and venography that permit to identify five types of venous malformations and four major (A-D) hemodynamic patterns of anomalous extracranial-extravertebral venous outflow. We investigated possible correlation between such hemodynamic patterns and both the symptoms at onset and clinical course in patients with MS and CCSVI.
METHODS: TCCS-ECD, selective venography and clinical records of 65 patients affected by definite MS and CCSVI were reviewed.
RESULTS: The four hemodynamic patterns of CCSVI were unevenly (P<0.0001) distributed with respect to the types of clinical presentation and course. In particular the Type A or B patterns were common in patients with onset of optic neuritis, but rare in patients presenting with spinal cord symptoms who typically showed a type D pattern. As well, the type A or type B hemodynamic were more common in patients with relapsing remitting course than in patients with secondary progressive course and rare in patients with primary progressive course. The C hemodynamic pattern was not observed in patients with primary progressive course who showed a remarkable prevalence of the type D pattern.
CONCLUSION: The distribution of venous malformations and the resulting hemodynamic pattern show correlation with symptoms at onset and clinical course in patients with MS and CCSVI.
