title: Episodes of flushing, dyspnea and hypertension after carotid stenting for severe carotid stenosis.
abstract: BACKGROUND
  Carotid angioplasty and stenting (CAS) is a treatment option for carotid stenosis in high surgical risk patients. As it implies instrumentation of the carotid bulb, baroreceptors dysfunction may be provoked with consequent hemodynamic instability.
  
  
  METHODS
  An 83-year-old woman treated by CAS presented with episodes of flushing, dyspnea and palpitations accompanied by transitory desaturation, hypertension, agitation and anxiety. Symptoms started 12h after the procedure. Each episode lasted 10 min. Five episodes in 3 days were observed.
  
  
  CONCLUSIONS
  A dysfunction of the carotid baroreceptors and chemoreceptors was hypothesized.
