Sir,
Reading of the Editorial published on Neurology by Bourdette and Cohen, who claimed for ending a therapeutic CCSVI in MS misadventure, we would briefly discuss on how to prevent it.1
Envisaging brain and cord changes that relate to the more central venous changes of CCSVI is the first step.
The diagnosis of CCSVI is based upon venous flow reversals, narrowings, and direct or position-dependent signs of venous stasis. The related flow reversals deep in the brain find little attention.2,3
Bedside diagnoses of MS have no concrete identifying features. They rely on cryptogenic neurodysfunctions perchance fitting in with pragmatically convened on patterns of a progression in time. Writing statistics on the co-occurrence of CCSVI with cerebrospinal dysfunctions defined but by numbers and times cannot but breed further misadventures.3
A recent re-evaluation of CCSVI criterion two, the expiratory cerebral venous flow reversal stresses its topical relevance.2
Corresponding pressure surges arise during compressions of extracranial veins in dependence of some hindrance to the venting of pressurized venous blood in direction of the heart and an insufficient venting via collaterals. CCSVI criterion two directly explains the emergence of the vein-specific brain pathology peculiar to MS.4,5
Focusing on the vein-specific MS symptom relationship and further research on the topic will prevent us from ruining the prospects of CCSVI-MS patients desperate for a cure.
