Re: twisty jugular vein image

The reference indicates this was the IJV for a hemodialysis patient for whom previous cannulations may have been through this IJV. This could leave a bit of scarring which, combined, with the tendency for the flow through curves and stenoses to be helical in nature (google "helical flow index"), may...

Re: Bidirectional flow in the fine veins

It seems to have been well received, in that quite a number of audience members were taking pictures of the slides as I presented them. It was presented in a brief format on the second stage, not the main stage, with perhaps 30 to 40 in attendance. There were no questions after the presentation, but...

Re: Bidirectional flow in the fine veins

The content of the two papers is encapsulated in the abstract for a presentation I made at ISNVD in Ferrara a few weeks ago, as follows: "Fluid Dynamics of Venous Flow in Multiple Sclerosis Trevor Tucker (PhD) Abstract Background Venous insufficiency in multiple sclerosis (MS) has often been associa...

Re: Bidirectional flow in the fine veins

You captured the premise precisely. The venous malformations in MS appear to be similar to atherosclerosis (artery) malformations which are now widely accepted to be related to low and reversing blood flow shear stress. (ie hardening of the veins.)

Re: Bidirectional flow in the fine veins

Thank you for citing this cerebrospinal venous flow paper Cece. There is a second paper also scheduled for publication in Medical Hypotheses which addresses the impact of vortex flow on valves and intraluminal growths like webs and septa in the major veins in the thoracic cavity. The abstract is at ...
