We present our results of carotid endarterectomy performed in 12 patients(bilateral in 2
patients) under prospective brain protection-monitoring protocol during the past two
years. The protocol consists of induced hypertension. mild hypothermia, and pentothal
burst suppression under bipolar two-channel compressed spectral array(CSA) monitoring.
Eleven of the 12 patients recovered without any new deficit from the surgery, and this
result was expected as their CSA monitoring showed no significant changes. One patient
had multiple untreated aneurysms, and therefore, hypertension was not applied. This
patient developed significant postoperative neurological deficits correlated well with the
CSA changes, One of the major advantages of CSA monitoring is that dosage of
thiopental sodium for burst suppression that varied greatly from 1,016mg to 3,330mg.
could be titrated on each patient based upon the CSA findings. Another important
benefit of our brain protection under CSA monitoring could prevent dangerous shunting
procedure could be avoided. In conclusion, brain protection under CSA monitoring could
prevent dangerous ischemic insults from circulatory disruption on already vulnerable
ischemic in patients requiring carotid endarterectomy.
