No Surgery All Safe: Not even med tx all safe. Stenosis: a late symptom of atherosclerosis in artery walls; starts in childhood, asymptomatic for decades as artery walls thicken & enlarge. Narrowing: due to plaque rupture & clots. Primary drivers: lipoproteins (not cholesterol), blood sugar, BP + others. Best/safest optimize NMR particle text, hba1c, bp, etc 1st to ↓↓ ds. Surgery promoted to ↓ narrowing; risk: stroke.

Need Surgery: Acas trial in United States showed benefit of surgery for over 60% stenosis with risk reduction over 5 years. You want to make sure that you see experienced vascular surgeon.If you are a good anesthetic risk you should do fine and be able to go home day after surgery.

2nd opinion: A 70% blockage in an 80 year old female without stroke or ministroke should be observed. It is a marker for generalized atherosclerosis and you should be seeing your primary doctor (or cardiologist) for further advice. If your carotid artery gave you some trouble (stroke / mini-stroke) I'd consider repair by carotid endarterectomy. That surgery in good hands is quite safe. Get a 2nd opinion.
