A member asked:

I have a 100% occluded right intercranial internal carotid and a 50% narrowed left intercranial carotid. at what point is the left a worry?

A doctor has provided 1 answer

Symptoms: If you have symptoms of a TIA ("ministroke") or 70% or more narrowing on the left. Meanwhile, the person you're describing should be on aspirin or plavix (clopidogrel) and a statin drug (to lower cholesterol) with optimal blood pressure.
