March 29, 2012 (San Francisco) -- Most patients in two new studies said that their multiple sclerosis got better after doctors cleared blockages from their veins.

Researchers reported their results earlier this week at the Society of Interventional Radiology's annual meeting.

"It's a nice experience with a large group of patients," Michael Dake, MD, tells WebMD. He was not part of either study. Dake is a surgery professor at Stanford University in California.

But another expert warns that the studies don't prove the procedure works. Lily Jung Henson, MD, tells WebMD that multiple sclerosis patients should not try the procedure yet. Henson is a neurology professor at the University of Washington. She was not part of the new studies.
