Percentage of carotid artery block

Patient : Is a 50% blockage in the coratid artery something to be concerned about ?
Doctor :   Typically a 70% or greater amount of blockage of the carotid artery is considered significant.The blockage basically dec reases the blood supply to the brain and thus can lead to a stroke. However this amount of blocakge is not significant but can be followed up as the years go by or reviewed in case of symptoms appearing.All the best.
