I don't know if this method has any merit. For sure it is not the usual angioplasty. If anybody has more information, please share it here.
It seems that they remove stem cells from your bone marrow and they inject them into the spinal fluid, I suppose trying to fix the wrongly formed veins.
I am not an English native speaker and maybe I got something wrong. Any correction is also welcomed.

EDIT: It seems that the stem cell treatment is not for the veins but to recover from the MS lesions. It is just a double way treatment.
