[Q]: Question: Do s-100beta protein levels correlate with stroke in patients undergoing carotid endarterectomy under general anesthesia?
Answer: S-100 concentration slightly increased at the end of surgery and remained high until the first postoperative day in all patients. S-100 was not significantly different in the patients with postoperative stroke. S-100 did not serve as a marker for postoperative stroke after carotid artery surgery. This fact must be taken into account during further investigations of S-100.
