My mom is 90 years old with asymptomatic 80% blocked carotid artery . on aggrenox. bp and cholesterol well controlled. ? advise surgery tx or stent?

CEA or nothing: Carotid stents are relatively contraindicated in > 80 yrs old; CEA (endarterectomy) is high risk but safe in competent hands. The risk of heart attack is elevated in CEA pts > 80 yrs old, while stroke was higher (and more disabling) w/ stents (cas). In pts > 80 yrs old w/ good heart, lungs , and kidney fxn, CEA is tolerated well. Aspirin & Plavix (clopidogrel) is not superior to stroke prevention v. Cea.

Best to discuss: Your mother's case with a neurologist. Make sure she is really not having symptoms. Cta scan with perfusion can see how the flow to her brain is affected by the narrowing. Abnormal perfusion suggests that treatment is necessary. Your neurologist will help you decide between stenting and surgery. I routinely stent people over 80 and have stented a few 90 year olds. Stents are safe.
