Objective: To evaluate the related risk factors of cerebrovascular complications after carotid endarterectomy (CEA) and to improve the efficacy of CEA in the treatment of ischemic stroke. Methods: The clinical data of 295 patients with atherosclerotic carotid artery stenosis who underwent CEA in the Department of Vascular Surgery, Beijing Anzhen Hospital, Capital Medical University from January 2013 to March 2017 were retrospectively analyzed. Results: As the results of the single-factor analysis of logistics, severe lower limb artery stenosis (RR=5.667, P=0.017), systolic blood pressure before the carotid artery clamping (RR=6.659, P=0.010), diastolic blood pressure before the carotid artery clamping (RR=3.981, P=0.046), stump pressure (RR=5.359, P=0.021), diastolic blood pressure after surgery (RR=9.550, P=0.002), diastolic blood pressure of the first day after surgery (RR=7.932, P=0.005) were influencing factors of postoperative cerebrovascular complications after CEA. The results of multi-factor analysis of logistic regression indicated that diastolic blood pressure before the carotid artery clamping (RR=0.953, P=0.024) and stump pressure to basic systolic blood pressure index (SSI)>0.25 (RR=0.086, P=0.049) were independent risk factors for postoperative cerebrovascular complications after CEA. Conclusion: Systolic blood pressure before carotid artery clamping and SSI>0.25 are independent risk factors for postoperative cerebrovascular complications after CEA. Close follow-up and drug treatment for patients after CEA might be beneficial to reduce postoperative carotid artery restenosis.
