Spinal cord Ischemia and vascular issues of the cord.

Thanks Dr. Flanagan found it first hit;

"Spinal cord ischemia can result from many causes. Obstruction of arterial blood supply to the spinal cord is the most commonly cited cause of spinal cord ischemia. Ischemic myelopathy of the spinal cord is frequently misdiagnosed as transverse myelitis. Also, many cases of spinal cord ischemia are attributed to other causes. For example, arteriovenous malformations cause ischemia. Compression of the spinal cord also can cause ischemia. Perhaps the most under appreciated cause of spinal cord ischemia is venous obstruction or congestion. Although the venous system is redundant, it is also a low pressure system that is susceptible to even mild compression and elevated venous pressures.

Spinal cord injury due to arterial, venous, and cerebrospinal fluid obstruction is far more common than we think. It is likely that they contribute significantly to the severity of spinal cord injury and failure of recovery in many causes of traumatic spinal cord injury where failure to decompress the injury site for days or weeks, poor maintenance of perfusion pressure, increased central venous pressure, and development of enlarging spinal cysts may contribute to lack of recovery or loss of function in chronic spinal cord injury"

Great article,

remarkable, yet mainstream wants these symptoms they named ms all in one pot. that's very interesting nzer.

The link didn't work for me, but I found it on google and shortened/fixed the link. Here ya go: http://bit.ly/vWLus1

Talk about WOW factor, what a great read. Shows how critical a healthy, and free flowing venous system is when it comes to proper neurologic and spinal function. How Zamboni's hypothesis can be dismissed outright (by some) with nary a second glance is beyond me. Very interesting about the CSF too, always wondered about that, quantities, flow etc. Thanks for the post ( and tiny url)

Very interesting.

Before talking about CCSVI one should give this to a "sceptical" neuro.

Ha! Yes SE, I would also add, that anyone new to CCSVI, read this first, to get a feel for how the interplay between arterial/venous/CSF works, so that the dysfunctional makes more sense. It's so intriguing anyways. We sure are wonderfully made...

Wonderfully made and poorly understood!
Thanks every one for your comments, and help with the link!

The problem with the link was due to copying and pasting from your other post. The new forum software automatically shortens the display of long URLs. However, a simple copy will not pick up the characters in the URL that are not displayed. The work-around is to click edit on your prior post and copy and paste from there. After copying the text with the complete URL, click cancel to close the edit screen. If it's not your own post that you're copying from, then you will need to copy the complete URL in a separate step. For example, right click on the link and select "copy link location" or whatever option your browser provides. Lastly, if the URL is not so long that it causes horizontal scrolling of the forum page, then you can prevent the automatic shortening by using [url] [/url] BBCode tags around the link.

That is the safest way I think, but another quick way for those of you that have a two button mouse (ie mostly windows), you can "right click" on a link (in most common browsers), and then select "Copy Shortcut" from the pop-up menu, and then paste it (Ctrl-V on the keyboard in windows, or right click and select "paste") into your reply.

And if you want the link off someone else's post, you can of course click the "quote" button on that post, to see the full link within their post, if your not comfortable with the right click method.

The "right click" method works in most places/links across the web (just not in scripted links etc)

Link did not work for me too.

The venous system, like the arterial system, has many redundant and alternative flow patterns that can withstand occlusion of one or more veins.

This is a quote from the article and I believe it to be the big question of CCSVI.

(Can the system withstand the occlusion of one or more vein? At what point do redundancies and alternatives fail? My own experience that, even with a now-fully-functioning right jugular, having my little left jugular re-opened resulting in improvements says to me that even one occlusion in one major vein (jugular) can have an effect, particularly if the organ it drains is already in a precarious state from previous damage.)

I kind of agree on this Cece. I think that as a broad statement there are alternatives in the Venus system. 'And' some of the alternatives overload the alternative route and that causes a double problem that can be causing more and different problems to the original. All areas in our brains require flow and when the flow is disrupted it is not one but many flow paths that will be effected and backed up.

We are working with cause and effect that is a mine field to map the dynamics.

Simply opening one path way eg a jugular effects the entire system. The pressure changes, the flow paths, the direction of flow, the volume of flow in a given area, the decrease of flow through the alternative region and so many other fluid dynamics that interplay when fluid is rerouted. Opening a jugular could be detrimental to another area, we simply don't know what is changing, and we need to know what the change of flow is 'doing' to the symptoms, why there is symptom change after flow changes.
Food for thought,
Nigel

I have yet to complete a thorough read of the article, but if anyone wants a more printer friendly version, then you can get it from here.
