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 investigate the risk factors of persistent hypotension after carotid artery balloon stenting (CAAS). Methods A total of 177 patients with CAAS were collected to analyze the risk factors of persistent hypotension after operation. Results In 177 cases, 92 cases of persistent hypotension occurred. Univariate analysis showed that balloon diameter, balloon length, number of dilatation, duration of dilatation, dilation pressure and bilateral carotid stenting were associated with postoperative persistent hypotension (P <0.05). Logistic regression analysis of Forward LR suggested that bilateral carotid stenting, balloon dilation duration ≥5s, balloon dilation pressure> 8atm is an independent risk factor for postoperative persistent hypotension. Conclusions Bilateral carotid stenting, balloon dilation pressure> 8atm, duration of expansion ≥ 5s patients prone to persistent hypotension.
