There's recognition of CCSVI in Australia and China. Here's a new abstract describing 4 cases of lesions potentially attributed to impaired venous drainage.
Wedge-shaped medullary lesions in multiple sclerosis
The clinical features and MRI characteristics of the medullary lesions suggest an impairment of venous drainage.
We propose that the formation of these wedge-shaped lesions may be related to the pattern of venous drainage in the ventral medulla and raised venous pressure due to chronic cerebrospinal venous insufficiency which has recently been described in MS.
So nice to see the "research" expanding.
Take care all (if it applies, stay warm too )
