The Relationship between Carotid Stump Pressure and Changes in Motor-Evoked Potentials in Carotid Endarterectomy Patients

摘要

BackgroundThe threshold of ischemic tolerance has not been completely identified in human clinical studies. Distal carotid artery pressure can be easily measured through the internal shunt tube during carotid endarterectomy (CEA). To confirm the critical threshold of intracranial arterial pressure and its maximum duration, we investigated the distal internal carotid artery (ICA) pressure and motor-evoked potential (MEP) changes during ICA clamping.
