Electromagnetic Flowmetry in Bypass Shunt During Carotid Endarterectomy

By use of a custom-designed electromagnetic flow probe, continuous measurement of flow in a bypass shunt system is possible. This permits real-time evaluation of shunt function during carotid endarterectomy and will allow evaluation of changes made in future shunt designs. Although limited to the carotid circulation in this study, the method has applicability to any vascular region where bypass shunts are used.
