I had my flow diversion stent procedure done on June 2 2021. I had my follow-up MRI 2 weeks ago which showed some issues so I had an angiogram completed this week and I’ve just heard from the doctors that my artery (right carotid) is nearly blocked at the stent site so I’m scheduled to have an angioplasty balloon procedure dec 3 2021. My doctor said it’s only about 50% successful and if it doesn’t work I might need a bypass or something else. I’m wondering what others experiences have been. Has anyone else had the flow diversion stent procedure result in needing an angioplasty? What was your experience with it? Any information would be helpful to ease my anxiety.
