title: [Cerebral monitoring with somatosensory evoked potentials in carotid surgery. A review of 141 carotids].
abstract: OBJECTIVE
  To evaluate postoperative and mid-term results of carotid surgery (CS) with somatosensory evoked potentials (SEP) monitoring.
  
  
  METHODS
  Between 1998 and 2006, 141 CS in 124 patients were performed under general anesthesia. Selective shunting was based on SEP abnormality. Shunting criteria were: reduction up to 50% of the amplitude or latency increasing up to 10%. Early results and follow-up data are analyzed retrospectively.
  
  
  RESULTS
  Shunting rate was 6%, 3 strokes (two transient strokes) occurred and one patient died of perioperative myocardial ischemia. The cumulative stroke and death rate at 30 days was 1.4%.
  
  
  CONCLUSIONS
  Intra-operative SEP monitoring with selective shunting may be safely performed in carotid surgery.
