We investigated the flow patterns in the jugular veins
of two subject groups, one normal and one with suspected
anamolies, using MRI-based CFD. Our results show that
there are two types of venous geometries and flow
patterns: (1) One which has helical flow in the jugular
bulb (the junction between the sigmoid sinus and jugular
vein), which results in a relatively straight flow in
the jugular vein; (2) and another in which the jugular
bulb is shaped such that it redirects flow at a right
angle to the jugular vein, which creates pronounced
helical flow pattern.
