New research: Using a new ultrasound cerebral venous return model, people with CCSVI have 70% less blood returning through the jugular veins when supine than healthy controls. This leads to activation of collateral veins and longer cerebral circulation time in those with CCSVI. Full paper available at link.

The quantification of the flow returning from the head through the cervical veins and the collaterals of the internal jugular vein (IJV), is becoming of prominent interest in clinical practice. We developed a novel model to calculate the cerebral venous return, normalized to the arterial inflow, in…
