Venography without a qualifier such as MR is a roentgenographic examination of veins. Selective is when it is applied to selected veins. A recent paper about the different methodologies for the diagnosis of CCSVI is the following "Use of neck magnetic resonance venography, Doppler sonography and selective venography for diagnosis of chronic cerebrospinal venous insufficiency: a pilot study in multiple sclerosis patients and healthy controls."( http://www.fondazionehilarescere.org/pd ... 5-ANGY.pdf)Cece wrote:I googled "selective venous angiography" and got this:
It mentions selective arterial and venous MR angiography being compared with "intraarterial venography" which is the gold standard. It also compares selective arterial MRA vs nonselective arterial MRA. Selective must be MRA terminology. Conclusion is that the selective arterial MR angiography is a powerful noninvasive method.
(Interestingly it separately says that the MR of the venous system is an "accurate" evaluation. Powerful beats accurate, is it saying that MR angiography is a better tool for evaluation of arteries than it is for veins? This was an AVM article, it was looking at cerebral drainage CCSVI-relevant veins.)
Cheer has a list of a gazillion things that negatively impact the venous system! It's all in her endothelial health regimen.
The Beirut study finds that CCSVI is less common in pwCIS and more common in pwMS. So they argue that this may mean that CCSVI is a late secondary phenomenon, possibly related to chronic central nervous system (CNS) disease and atrophy. I ask if this could also mean that having MS, there may also be another factor for the deterioration of veins (e.g. a virus) or if this could be a property of the malformations (truncular vs. extratruncular). I know there are no clear answers yet, but I would like to know what Dr. Sclafani thinks about it.
