[Continuous EEG monitoring in carotid surgery].

From March 1980 to March 1987, at the Department of Vascular Surgery of the University of Padua, 217 patients underwent 252 carotid revascularizations with routine use of an intraluminal shunt (IS) for symptomatic (70%) or asymptomatic (30%) internal carotid artery (ICA) atherosclerotic stenosis. All carotid endarterectomies (CEs) were routinely performed with patch graft angioplasty to prevent restenosis. In the immediate post-operative period, no patient presented permanent or transient neurological deficits; no patient died. In the early post-operative course there was a 0.9% (2 patients) stroke rate and 0.4% (1 patient) mortality rate. These results suggest that the selective use of the IS on the basis of EEG changes is able to reduce the perioperative morbidity and mortality to nearly zero.
