Dr. Zamboni collaborates with Dr. Beggs, a specialist in fluid dynamics. They use a cervical collar gage to measure hydrolic resistance and find blood flow is very different in CCSVI.
The mean hydraulic resistance of the extracranial venous system was 10.28 mmHg.s/mL in the healthy controls and 16.81 in the CCSVI patients.
Conclusions: The haemodynamics of the extracranial venous system are greatly altered in CCSVI patients.

ObjectiveWhile chronic cerebrospinal venous insufficiency (CCSVI) can be characterized using cervical plethysmography, much remains unknown about the haemodynamics associated with this procedure. The aim of the study was therefore to gain a deeper understanding of the observe...
