In the study, 40 people with MS underwent an array of tests before the venoplasty treatment and then at intervals of one month, three months, six months and one year after the procedure. These tests included questionnaires, MRI scans, and a standardised test used to assess function (manual dexterity, ability to walk and mental acuity).
The researchers found no difference between the 30 people who had been treated by the venoplasty and ten people who had not. The initial benefits reported by people who had received the procedure, such as more energy or better balance, tailed off over time, with a drop-off after three months. After a year, about a quarter had had a recurrence of blocked veins though showed no reduced function when compared to those where the blocked veins did not recur.
Dr. Pryse-Phillips said the study was set up so that he didn’t know which participants had undergone venoplasty and which had not.
Dr. Pryse-Phillips also noted that by the 12-month check up, about a quarter of the patients who had undergone venoplasty had blocked veins – either a clot in or the closure of one or more neck veins. But there was no difference, function-wise, in these patients as compared to the 75 per cent who didn’t have the clots or blockages.
The study done by Pryse-Phillips did find there were subjective psychological and physical benefits, but he described those as “meagre” compared to the costs and the risks.

After reading specifics of the study I think there were some minor flaws but overall it appears to have been ran in an objective manner.
