A member asked:
What does less than 50% stenosis in bilateral corotid arteries actually mean?
5 doctors weighed in across 2 answers
Carotid stenosis: Any carotid stenosis means that you have significcant hardening of the arteries that should be treated aggressively. Less than 50% means that the risk of stroke over 5 years is low enough to warrant only aggressive medical therapy. Medical therapy includes blood thinners, cholesterol reducing medicine, and blood pressure medicine. Safe exercise is also very important.

Carotid disease: Any blood vessel may have a "blockage" due to internal clots/plaque or external pressure. The blockage can be graded and thus roughly estimated to be 25, 50, 50-75, more than 75%. Occasionally 60% is used as a cut off. Those numbers help to compare but also help to determine if blockage is significant enough to cause harm. Less than 50% says it is not significant. Test can monitor changes.
