Why the study?
Does selective shunting based on prior stroke or carotid back pressure < 25 mm Hg accurately determine shunt requirements in patients undergoing carotid endarterectomy?

Selective shunting criteria may avoid unnecessary shunts in CEA; leaves open whether this reduces perioperative stroke versus routine use.
Does selective shunting based on prior stroke or carotid back pressure < 25 mm Hg accurately determine shunt requirements in patients undergoing carotid endarterectomy?
The study describes the application of selective shunting criteria (prior stroke or back pressure < 25 mm Hg) during carotid endarterectomy, demonstrating that a significant portion of patients can avoid shunting.
Hunter et al. (1982) studied this question.
