Carotid surgery. Is regional anesthesia always appropriate?
We retrospectively studied a series of 385 carotid endarterectomies performed either under general anesthesia (242) or under local anesthesia (145) to compare the peri-operative mortality and morbidity rate and to identify factors which may influence the choice of anesthesia. The rate of transient ischaemic attacks (TIA), stroke, death, combined mortality, severe neurological and cardiac morbidity were not statistically different. Under general anesthesia, more shunts were inserted (17% versus 7%, p less than 0.05) and more myocardial infarctions occurred (5% versus 0%, p less than 0.05). However, more strokes due to technical imperfection were seen under regional anesthesia. We concluded that regional anesthesia is more appropriate in patients with coronary artery disease and in patients at risk of intolerance to cross clamping. General anesthesia is more appropriate in poorly cooperative patients or in those with unfavorable operative conditions.
