Abstract:
Objective To investigate the risk factors for persistent hemodynamic depression after carotid angioplasty and stenting(CAS). Methods Sixty-one patients with CAS were included. By univariate Logistic regression analysis,the influencing factors for persistent hemodynamic depression were analyzed,by stepwise Logistic regression analysis and adjustment for age and gender factors,the independent risk factors for persistent hemodynamic depression were analyzed. Results In 61 patients,25 cases had hypotension,25 cases had bradycardia,all for 41.0% incidence. According to the patients intraoperative and postoperative blood pressure,heart rate conditions,the duration of hemodynamic depression,the cases were divided into persistent hemodynamic depression group (20 cases) and no-persistent hemodynamic depression group(41 cases). Univariate Logistic regression analysis indicated that persistent hemodynamic depression influencing factors were the symptomatic stenosis, severe stenosis, using balloon dilatation, implantation of laser-carving stent(P<0.05). With adjustment for age and gender factors, stepwise Logistic regression analysis showed that using balloon dilatation, implantation of laser-carving stent were the independent risk factors for persistent hemodynamic depression (OR = 5.046,95%CI 1.342-18.977,P = 0.017;OR = 4.142,95%CI 1.151-14.902, P= 0.030),symptomatic stenosis was the independent protective factor for persistent hemodynamic depression (OR = 0.264,95% CI 0.073-0.964,P= 0.044). Conclusions Persistent hemodynamic depression after CAS is a common complication.CAS patients with using balloon dilatation, implantation of laser-carving stent are more susceptible to persistent hemodynamic depression, while symptomatic stenosis is its protective factor.
