Clinically, carotid plaques in eighty year olds that meet the indications are amenable to surgery, and even ninety year olds who are generally in good health can be considered for surgery. If the plaque is large, unstable or causes severe stenosis of the carotid artery (more than 70%), surgical thrombolysis or placement of balloon dilatation + stent placement can be considered. Surgery can be performed if the eighty-year-old is in good general condition and has no comorbid underlying disease. If the eighty-year-old carotid plaque is combined with poor underlying health conditions, such as heart disease, hypertension, kidney disease, etc., it is important to consider the risks associated with surgery and make good choices. Specifically, you can consult a specialized physician for advice.
