title: [Carotid artery stenting--an update].
abstract: OBJECTIVE
  Therapy of carotid stenosis should be based on an accurate assessment of the stenosis and a differentiation between symptomatic and asymptomatic patients.
  
  
  METHODS
  According to current guidelines carotid artery stenting (CAS) can be considered as an established therapeutic alternative to carotid endarterectomy (CEA).
  
  
  METHODS
  For the therapy of carotid stenosis CAS has become established as a minimally invasive alternative to CEA because the complication rate has been reduced due to growing experience, technical innovations and external quality assessment.
  
  
  METHODS
  The CAS procedure should be performed in centers with documented complication rates of < 3 % for asymptomatic and < 6 % for symptomatic stenoses.
  
  
  RESULTS
  Overall there are no significant differences between CAS and CEA in the treatment of carotid stenosis concerning the secondary prophylactic effect.
  
  
  CONCLUSIONS
  Ideally an interdisciplinary approach should be chosen for the therapy regime. Revascularization of asymptomatic stenoses should be considered critically as these patients might profit from optimized conservative medicinal therapy.
