Abstract
BACKGROUND AND STUDY AIMS: Both general anesthesia (GA) and local anesthesia (LA) are used in our department for carotid endarterectomy. The decision of which anesthetic technique to use during surgery is made on an individual basis.
The aim of our study was to analyze the reasons for using GA or LA. MATERIAL AND METHODS: The reasons that led to the selection of either GA or LA were analyzed retrospectively in a group of 409 patients.
RESULTS: GA was used in 304 patients (74%) and LA in 105 patients (26%). The reasons for a preference for GA were clopidogrel use (88 patients), patient preference (80), increased risk of shunt insertion (43), unfavorable anatomical conditions (41), surgeon preference (21), simultaneous carotid endarterectomy and cardiac surgery (18), emergent carotid endarterectomy (12), and sleep apnea syndrome (1).
The reasons for selecting LA were internal comorbidities (46 patients), patient preference (39), unavailability of intraoperative electrophysiologic monitoring (15), and pacemaker (5). CONCLUSION: GA is the dominant choice for carotid endarterectomy in our department because of its prevailing benefits and its preference among neurosurgeons and patients.
However, in some subgroups of patients, LA is preferable. An optimal approach is therefore an individual indication for both anesthesia techniques.
