title: [Related factors of hemodynamic damage after carotid artery stenting].
abstract: OBJECTIVE
  To analyze correlation factors of hemodynamic damage after carotid artery stenting.
  
  
  METHODS
  In this study, 66 cases (71 lesions) who undertook carotid artery stenting were collected and the correlation factors of hemodynamic damage were analyzed.
  
  
  RESULTS
  Hemodynamic damage emerged in 23 cases (32.4%), of which, 11.3% developed hypotension. The distance between bifurcation and lesions (P=0.0020), plaque distribution (P=0.0002), plaque character (P=0.0019), post-dilation (P=0.0026) were associated with hemodynamic damage by single factor analysis. However, only eccentric plaque (P=0.0153) and calcified plaque (P=0.0097) were associated with hemodynamic damage by multiple factors analysis. All the patients could reach stable circulation by drugs during operation, and no cerebral ischemic events (transient ischemic attack or stroke) and cardiovascular ischemic events happened.
  
  
  CONCLUSIONS
  The distance between bifurcation and lesions, eccentric plaques, calcified plaques are correlation factors of hemodynamic damage.
