The treatment for cerebrospinal venous insuffienciency (CCSVI) in people with multiple sclerosis (MS) is usually balloon angioplasty - the procedure is often called "Liberation Therapy."

The doctors who typically perform this procedure are interventional radiologists (IRs), doctors who do surgery or diagnose disorders using radiological images. The whole idea is that the images will help the doctors diagnose or treat in the least invasive way - instead of cutting patients open to find out what is going on and then fix it, IRs use images to show them a picture of the problem and allow them to get to the exact spot to correct it with tiny instruments, such as needles and catheters.
