While waiting on Poland, I managed a standard (not proper protocol) MRV. I know this is not the end of my vein story, but it did show a completely occluded (or very near) left transverse dural sinus. Also, the left jugular was "small." The interventional neuroradiologist guessed it was 1/4 the size it should be, but couldn't be certain from the picture and said virtually all my drainage was taking place on the right side. He was ready to set me up for an angiogram based on the MRV, but following our discussion, he is getting up to speed on CCSVI first. I welcome any thoughts on the significance of the sinus blockage related to CCSVI. I recall Melissa's was quite stenosed but Dake thought it was too risky to treat, but that's my only reference point. Not sure if collateral veins work fine when they are bypassing the sinus, but just not in the jugs? I'm also curious about a jugular that is small all the way down, rather that having a specific stenosed point. To my untrained eye, the picture of my veins looked like the entire left side was atrophied or shriveled up compared to the right. I'd appreciate any thoughts.
