Abstract:
Objective To investigate the risk factors for carotid sinus reactions (CSR) during internal carotid artery stenting (CAS).Methods The clinical data of 36 patients treated with CAS were enrolled retrospectively.The patients were divided into either a CSR group or a non-CSR group according to whether they had CSR or not.The risk factors for CSR during procedure were analyzed using univariate and multivariate logistic regression analysis.Results Of the 36 patients,25 had CRS (7 simple hypotension,4 simple bradycardia,and 14 both co-existence).The constituent ratios of the patients of the age ≥ 75 years (64.00％ vs.27.27％ ;x2 =2.384,P =0.028),degree of CAS 70％ to 99％ (76.00％ vs.36.36％ ; x2 =4.430,P =0.035),symptomatic stenosis (72.00％ vs.36.36％ ; x2 =4.082,P =0.043),calcified plaque (76.00％ vs.36.36％ ;x2 =4.430,P =0.035),distance from stenosis to bifurcation ≤ 10 mm (72.00％ vs.27.27％ ;x2 =5.029,P =0.025) and balloon expansion (64.00％ vs.18.18％ ;x2 =44.483,P =0.000) in the CSR group were significantly higher than those in the non-CSR group.Multivariate logistic regression analysis showed that age ≥ 75 years (odds ratio [OR] 1.520,95％ confidence interval [CI] 1.376-4.369; P =0.034),distance from stenosis to bifurcation ≤ 10 wm (OR 2.432,95％ CI 2.423-3.421; P =0.041) and balloon expansion (OR 3.631,95％ CI 1.764-4.738; P=0.003) were the independent risk factors for occurring CSR during CAS.Conclusions CSR is a common perforrance during CAS.Advanced age,distance from stenosis to bifurcation ≤ 10 mm and balloon expansion are the independent risk factors for occurring CSR.
