Dr. Zamboni found that progressive MS patients with the worst mobility issues had azygos blockage, which he opened up and the vein remained patent in 97% of the cases...much better than the jugulars. But he also found that a few patients were missing a lumbar vein completely, and there was nothing he could do to help those cases. When a person is born without a vein it is called agenesis.
and TMrox is right...we need to understand what it causing the demyelination. Here is a study I linked to a in the first CCSVI discussion. It describes three autopsy cases of venous myelopathy...all had demyelination of the spine, all had different diagnoses..one was even "MS." But all had enlarged, torturous veins. Doesn't matter what you call it...it matters what is really going on...

We describe three patients with progressive myelopathy, in whom autopsy revealed spinal cord pathology compatible with that of venous congestive myelopathy (VCM) associated with dural arteriovenous fistula (AVF), formerly known as angiodysgenetic necrotizing myelopathy (Foix-Alajournine syndrome). In these three patients, common symptoms were gait disturbance and sensory disturbance of the extremities, and these symptoms slowly worsened. The clinical diagnoses varied and included spinal cord intramedullary tumor, cervical spondylosis and multiple sclerosis.
At autopsy, all the patients showed enlarged, tortuous venous vessels on the dorsal surfaces of the spinal cord at the affected levels. In the affected spinal cord parenchyma, necrotic lesions manifested by various degrees of neuronal loss and gliosis, with increased numbers of hyalinized vessels, were evident. The presence or absence of associated spinal dural AVF could not be identified histopathologically. Even with the help of modern neurological examination methods, early and accurate clinical diagnosis of VCM is sometimes difficult. When encountering patients with progressive myelopathy, VCM, although recognized as rare, should be considered as an important differential diagnosis.
