Can venoplasty help your multiple sclerosis symptoms?

By Mayo Clinic Staff

Venoplasty is a procedure that involves inserting an inflatable balloon to widen your veins and improve blood flow. It is also known as percutaneous, or balloon, venoplasty. Sometimes a tiny tube (stent) is inserted in the vein to keep the vein open.

Percutaneous venoplasty has been proposed as a treatment for symptoms of multiple sclerosis (MS) based on a theory about the role of vein abnormalities in the disease.

A proposed link

Although the underlying cause of MS is unknown, some researchers have proposed that there is a link between MS symptoms and narrowed veins or vein blockages in the head and neck that alter blood flow or drainage from the brain, a condition known as chronic cerebrospinal venous insufficiency (CCSVI).

However, recent studies have found that CCSVI is not exclusive to people who have MS and that healthy people and those with other neurologic diseases can also have the same vein abnormalities, indicating that they are not likely related to MS symptoms.

So far, studies of venoplasty for MS treatment have had many limitations, including not being randomized, placebo-controlled or blinded, and have not demonstrated any objective benefits on MS.
