In brief: Generally

Generally the major trials regarding decision making in carotid stenosis provide guidance at: 1) 70%, and 4) occluded (100%).
There are many other grades that have been developed and discussed, but their clinical utility from the vascular surgeon's perspective is limited. Discuss further with a board certified vascular surgeon.

In brief: Variable

They can be totally occluded or have non signicant plaque.
The degree of blockage is expressed in percentage so that 80% or greater is considered for intervention when unilateral or when associalted with symptons such as tias or if the other side is blocked at even lower percentage such as 70%.
