An intraarterial shunt for cerebral protection during carotid endarterectomy is described. It combines the features of the U-shaped shunt of Hallin and the straight shunt of Sundt, and incorporates a side-arm that can be used for perfusion, irrigation, and intraarterial pressure. The shunt is a molded Silastic tube with wire coils at each end to prevent collapse, and its funicular collar and rim obviate sudden expulsion. Its use allows endarterectomy to be performed in a deliberate manner, permitting careful attention to prevention of an intimal flap and unhurried repair of the arteriotomy.
