Please read part one of this article for an introduction on balloon angioplasty.
Jugular and azygos veins were observed with selective venography and intravascular ultrasound. Imaging identified stenosis in 94.9 percent of the patients. A total of 179 veins displayed venous stenosis. Balloon angioplasty was performed if the imaging picked up reflux, or showed a greater than 50 percent decrease in the vessel’s diameter. If needed, stents were then used to clear nonresponsive lesions or blockages. The patients were administered blood-thinning medication for the six weeks following CCSVI treatment.
Ferral’s team saw symptomatic improvement in 55 percent of the people treated, and 38 percent felt no improvement. Seven percent of patients did not attend their follow-up visits and were considered to be lost to follow-up. Jugular thrombosis occurred in three patients and bleeding at puncture site was experienced by three patients.
Almost 60 percent of patients with relapsing remitting MS saw an improvement in their symptoms, the highest of all the subgroups taking part in this study.
In 2011, members of the SIR panel expressed that evaluating patients with MS who have narrowed jugular and azygos veins, and looking at the value of widening those veins with balloon angioplasty, would require careful, well-designed research. The multidisciplinary panel communicated that the “mandatory goal” should be large-scale, pivotal multicenter trials to explore chronic cerebrospinal venous insufficiency and balloon angioplasty further.
At Angeles Health we offer balloon angioplasty for CCSVI that is performed by our Stanford trained interventional radiologist as well as a neurologist so you are well taken care of. We keep our patients in hospital for up to five nights so they can become used to their medication before travelling home.
