Carotid Endarterectomy Occlusion Order

What is the order of clamp placement during carotid endarterectomy?

A. External, internal, common
B. Internal, common, external
C. External, common, internal
D. Common, external, internal
E. Common, internal, external

B. Internal followed by common and then external

“Placing the clamps on the internal carotid first, followed by the common and then the external carotid artery often ensures that any accumulated blood clot will be more likely to pass through the external rather than the internal carotid circulation.” Source
