The results of carotid endarterectomy can be improved by reducing the perioperative embolic and hemodynamic risks. Electrophysiologic monitoring, although reliable, cannot provide full information. In this study, we report on the combined use of transcranial Doppler (TCD) and electrophysiologic monitoring in 153 patients undergoing 166 carotid endarterectomy procedures. TCD monitoring confirmed the low incidence of intolerance to cross-clamp (1.8%), showing a good correlation with electrophysiologic monitoring. In addition, it frequently showed embolic signals immediately after clamp release, but never during carotid dissection or in the final operative phases. Furthermore, TCD allowed the detection of hyperperfusional flow patterns in four cases, making immediate and aggressive control of arterial pressure possible.

D009609	Nitrous Oxide	Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream.

D002561	Cerebrovascular Disorders	A spectrum of pathological conditions of impaired blood flow in the brain. They can involve vessels (ARTERIES or VEINS) in the CEREBRUM, the CEREBELLUM, and the BRAIN STEM. Major categories include INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; BRAIN ISCHEMIA; CEREBRAL HEMORRHAGE; and others.
