Welcome to HealingWell and I am so glad you found us. To the best of my knowledge, there is no surgery that can successfully re-open a carotid artery once it is 100% blocked. The brain will get blood from the other 2 arteries ( the vertebral arteries), but you will be at increased risk for having a stroke and will need to control your risk factors.

I hope you do talk with a Dr. who can guide on what things you should personally do to live as healthy as you can.
