via CCSVI in Multiple Sclerosis - "New neurological research notes that small internal jugular veins are related to multiple sclerosis severity. The researchers claim they have discovered something new and different than Dr. Zamboni, but they haven't.
Dr. Zamboni has already shown that venous malformations of the jugular veins contribute to CCSVI--hypoplasia, agenesis, and atresia all refer to veins that are either not fully opened (atresia), not fully formed (hypoplasia), or almost entirely missing (agenesis). This creates slowed venous drainage. And Dr. Zamboni has written about this." http://www.biomedcentral.com/1471-2377/13/90/abstract

Recent evidence has indicated an association between chronic cerebrospinal venous insufficiency (CCSVI) and multiple sclerosis. Small internal jugular veins (IJVs) (with a cross-sectional area of less than 0.4 cm2) have been previously described as difficult to catheterize, and their presence may po...
