title: [The feasibility study of prediction internal carotid artery whether can resection by monitoring carotid artery pressure preoperative].
abstract: OBJECTIVE
  Through preoperative temporary balloon occlusion of internal carotid artery and monitoring of carotid artery stump pressure variation, in order to further predict the risk of carotid artery ligation and resection, evaluation operative risk and provides the reference for the choice of surgical approach.
  
  
  METHODS
  Continuous monitoring and recording the carotid artery stump return pressure,before clamping and in the process of blocking, close observation the patients mental state and the nervous systemof all kinds of signs, in the process of blocking, to understand the dynamic change of stump artery pressure return in patients and whether can the smooth passage of carotid artery balloon occlusion test.
  
  
  RESULTS
  Of the 19 patients, 4 cases were positive, 15 negative cases, Blocking immediate the positive patients and negative patients with stump pressure drop was (57. 35 ± 1. 89) % and (38. 99 ± 12. 23) %, with statistical significance between the two, in the process of blocking, the mean stump pressure of the positive patients and the negative patients was (37. 29 ± 3. 15) mmHg and (61. 36 ± 14. 69) mmHg, with statistical significance between the two.
  
  
  CONCLUSIONS
  Approximately 21. 05% of patients can not tolerate carotid artery balloon occlusion test, theory for carotid artery reconstruction operation. After blocking the stump pressure is less than 40. 44 mmHg, the theory for reconstruction of the internal carotid artery operation. Blocking instant artery stump pressure dropped more than 55. 46%, in theory the need for internal carotid artery reconstruction.
