Schreiber and colleagues also investigated human cerebral venous blood drainage with color-coded duplex ultrasound. In their first study, they reported that total venous blood flow at rest was 766 ± 226 mL/minute in healthy human volunteers in the supine position, with the majority of flow through the internal jugular veins (720 ± 232 mL/minute) and a small amount of flow (47 ± 33mL/ minute) through the vertebral veins. In a later study, they found that 6% of healthy human volunteers had a predominantly nonjugular pattern of cerebral venous drainage when in the supine position.
If nonjugular pattern of cerebral venous drainage can be considered akin to CCSVI, this is nearly identical to Dr. Haacke's findings of 8% of healthy volunteers had CCSVI.
Only if the reason they didn't use their jugulars was because they couldn't, and what's more, what is really the problem with a non-jugular drainage when supine? How healthy is healthy? How insufficient is insufficient? How can you be both?
