I see ligation of the ijv is used for treatment of neo-natal middle air infections that spread. Below study observes collaterals in these cases.

Question- would one not expect to see MS develop in these cases if ccsvi is the cause of MS?

Poor kid!

Here's an intriguing title with no article or abstact printed:
http://www.ncbi.nlm.nih.gov/pubmed/11347652
"A warning on venous ligation for pulsatile tinnitus."

edit: here are some of the contents of this research, cited in another article

However, this is not without risk, as IJV occlusion has been reported to engender
intracranial hypertension, cerebral venous ischemia, superior vena cava syndrome and even pulmonary embolism
secondary to dislodgment of clot

IJV occlusion can't lead to superior vena cava syndrome, can it? It could lead to symptoms similar to superior vena cava syndrome that warrant its own syndrome name (ccsvi syndrome).

According to Zamboni two venous problems are required for CCSVI. It seems taht there is enough redundancy in the venous system to stand this intervention. Only children with a second venous problem would be in danger for MS.

It appears the procedure is not uncommon (treatment for tinitus) and also in situations of cancer multiple veins are ligated (see below)

Perhaps this is one reason that the findings of narrowings are eliciting a 'so what' from those familiar with the pathology of ijvs. Narrowing or ligating jugular veins is performed surgically without any apparent issue. This suggests to me that ccsvi is a symptom with associated fatigue rather than a cause of ms

In mid 1980s I discovered that pulsatilla tinnitus could be cured by ligation of the jugular vein. Interestingly the patient ( my wife) developed symptoms of cvs I (unrecognized by me)including fatigue migraine headaches heat intolerance and memory impairment. Fortunately these symptoms improved with time and collateral development

I would expect there to be something in the published literature involving these sorts of symptoms after jugular vein ligation, but I can't find it (other than the 2001 warning article listed above.) The only follow-up is looking at the symptom of tinnitus.

Wow, saved.

It is believed that the sacrifice of both jugular veins leads to increased intracranial pressure with subsequent neurological sequela (6).

Such as? "MS" slash CCSVI symptoms, perhaps?

I think it's safe to say that not enough is known about venous anatomy, collateral drainage etc. Everyone seems very different: maybe we only know about anatomy that is usually the same from one person to the next.

This poor cancer sufferer showed them, the hard way, that it does not have to be fatal, or cause neurological damage, even. Does that mean it's good to cut off some of your drainage? I have some doubts. For similar reasons a relatively safe venoplasty that unblocks it is very probably a good thing. Doctors don't like to tell you, but the "common" ligation procedure, on both IJVs, can lead to death. The fact that it doesn't always do so is no great praise of the practice, but sometimes certain death is the only alternative.

Veins are not disposable.
