颈动脉球囊扩张支架置入术后持续性低血压危险因素分析

Risk factors for prolonged hypotension after carotid artery angioplasty and stenting

目的探讨颈动脉球囊扩张支架置入(CAAS)术后发生持续性低血压的危险因素。方法收集CAAS术患者177例资料,分析术后发生持续性低血压的危险因素。结果 177例中,出现持续性低血压92例。单因素分析提示,球囊直径、球囊长度、扩张次数、扩张持续时间、扩张压力、双侧颈动脉支架与术后发生持续性低血压有关(P<0.05)。Logistic回归Forward LR法分析提示,双侧颈动脉支架、球囊扩张持续时间≥5s、球囊扩张压力>8atm是发生术后持续性低血压的独立危险因素。结论双侧颈动脉支架置入、球囊扩张压力>8atm、扩张持续时间≥5s的患者术后易出现持续性低血压。

Objective To analyze the risk factors for prolonged hypotension after carotid artery angioplasty and stenting（CAAS）.Methods Of 177 patients underwent CAAS,prolonged-hypotension （systolic blood pressure 90 mm Hg,lasted for more than 3 hours） occurred in 92 cases.The risk factors for prolonged hypotension were analyzed.Results Univariate analysis found that the balloon diameter,balloon length,multiple balloon dilation,the time of balloon dilation lasted for more than 5 seconds,the pressure of balloon dilation more than 8 atm and dipl-stenting were closely related with prolonged hypotention（P0.05）.Logistic regression model analysis showed that dipl-stenting,the time of balloon dilation lasted for more than 5 seconds and the dilation pressure more than 8 atm were the independent risk factors for prolonged hypotension after CAAS.Conclusion The patients underwent dipl-stenting,the time of balloon dilation lasted for more than 5 seconds and the balloon dilation pressure more than 8 atm are more likely to develop prolonged hypotension after CAAS.
