hi my grandmother had a tia this weekend and today they found she has 100% blocked carotid on one side and 75% on the other side.  He said they cant do anything with the 100% blocked. Should she have the 75% carotid unblocked?  She has been on Cholesterol medication for years, and this can still happen?
Yes she needs to be treated as she may have recurrent Ties in future as well. Consult with your doctor to start her with blood thinners and if any stenting is possible at this stage or not as she is at risk of her brain damage whenever this borrowing increases
