title: [Clinical selection of endovascular stenting and carotid endarterectomy in treatment of carotid artery stenosis].
abstract: OBJECTIVE
  To explore reasonable clinical decision in treating carotid artery stenosis under different conditions.
  
  
  METHODS
  The data of 133 carotid artery stenosis patients were retrospectively analyzed. Of the patients, 46 cases were treated with carotid angioplasty and stenting (CAS), 87 patients received carotid endarterectomy (CEA). The length of hospital stay and National Institutes of Health Stroke Scale (NIHSS) grade before and after treatment in both groups were observed; the forward flow were assessed by digital subtraction angiography (DSA) before and after treatment; the degree of carotid artery stenosis were determined by using ultrasound during 3 to 24 months after treatment in both groups; the cumulative incidence of major cardiovascular events was concentrated, including appearance of death, stroke or myocardial infarction during 30 days after CAS and CEA and death or homonymy stroke during 31 days to 2 years.
  
  
  RESULTS
  Significant difference was found in hospital stay and when NIHSS exceed 20 after treatment between the two groups (P < 0.05); there was no significant difference in the forward flow before and after treatment in both groups; the carotid artery stenosis had been improved significantly after the operation in both groups; the cumulative incidence of major cardiovascular events in CEA group was significantly higher than in CAS group in 30 days after the operation (P < 0.05), but no statistical difference in 31 days to 2 years after the operation.
  
  
  CONCLUSIONS
  CAS and CEA has equivalent effects in treating carotid artery stenosis, and should be selected according to the location of stenosis, etiological factors and the condition of opposite carotid artery.
