Intraoperative electroencephalography, somato-sensory evoked potentials and transcranial Doppler have been proposed to replace carotid artery stump pressure measurement (CASP) as the test of choice in the evaluation of cerebral tolerance during temporary carotid occlusion. CASP is a simple, inexpensive test that does not require an additional specialist in the operating room. Herein, we attempt to demonstrate that CASP is a reliable test that does not need to be replaced by more sophisticated and expensive techniques. ⋯ CASP > or = 45 mmHg was a reliable predictor of adequate cerebral perfusion during 1,135 consecutive CEAs performed under general anesthesia. The percentage of indwelling shunts utilized in this series was not significantly different from the ones using more expensive and sophisticated techniques.
