Hi tskeane, hope all is well with you, I do understand your concern I had the same when I was at 75% blockage what they said to me made no sense why wait until it is more blocked that what it is now? I do know someone who is blocked at 100% on one of the arteries in her neck and they wont touch it now.. they all confirm that there are other pathways there for the blood to supply your brain area with the needed blood.I know it is not an ideal way to live with this.... I actually checked on having the "TCAR" procedure done and at the time my vascular surgeon was not willing to use it because there was no past track record of success with it. I did have the carotid Endarterectomy done and so far is was a great success. I am not sure where you are I am in clearwater florida and of course I feel like i had the best surgeon in the world everyone I talked to really liked and trusted him. If I can do anything to help you please let me know, be well.....
