Let me ask a different way... Has anyone had the Percutaneous Balloon Compression?

I am interested to see who has had the Percutaneous Balloon Compression and was it successful?

My husband is scheduled for a Percutaneous Balloon Compression next week with Dr. Kenneth Casey. Dr. Casey perfomed a MVD 2 years ago and my husband had a lot of relief though not 100% even with continuing medications. Now is pain has returned with a vengence. I had not heard of the balloon procedure until a few weeks ago. Does anyone have experience or comments?
