A Calgary multiple sclerosis sufferer who recently received a controversial MS treatment in Costa Rica says he'd do it all over again.

Jordan York isn't fazed by the case of the Ontario man who died on Oct. 19, several months after going to the same Central American country for treatment and one day after doctors in Costa Rica tried to dissolve a blood-clot complication.

Both men received the MS vein therapy pioneered by Italian researcher Dr. Paolo Zamboni.

The so-called "liberation therapy" is based on a theory that narrowed neck veins cause blood-borne iron deposits to build up and damage brain cells, and that unblocking the veins will help people with multiple sclerosis.

The difference was that Mahir Mostic of St. Catharines had a stent put into his vein, a procedure the clinic has said it doesn't normally perform because it's considered risky.

But York had an angioplasty, which involves inserting a catheter into a vein and inflating it in order the clear the way.

York said he's now able to get up and walk on his own with a cane, something he couldn't do six weeks ago.

"You know this fellow that recently died, that's a tragedy. That's a terrible thing," said York. "And it's not just a tragedy for him and his family but for everybody with MS, because there will be people in the news media who are going to make a big deal out of it.

"I would never go somewhere and have a stent put in."
