目的:观察颈动脉支架成形术中血液动力学不稳定的发生率及其相关因素。方法:15例症状性颈动脉狭 窄患者在行血管内支架成形术时,观察其血压、心率的变化以及药物控制的疗效、围手术期有无并发症。结果:15例支 架放置全部成功,其中11例在进行颈动脉分叉部球囊扩张或支架释放时出现不同程度的心率减慢和血压下降,6例出 现颈动脉窦反应,在使用阿托品和多巴胺后均恢复正常。术中及术后无与血液动力学相关的脑低灌注或高灌注并发症。 结论:血液动力学不稳定是CAS中较为常见的并发症,可通过药物加以控制。
Objective: To observe the incidence of hemodynamic instability in carotid stenting and its related factors. Methods: Fifteen patients with symptomatic carotid stenosis underwent balloon angioplasty, observed the changes of blood pressure and heart rate, and the curative effect of drug control, and whether there were complications during perioperative period. Results: All the 15 cases were successfully placed. Among them, 11 cases underwent carotid artery bifurcation balloon dilatation or stent release with varying degrees of heart rate slowed down and blood pressure decreased, 6 cases of carotid sinus reaction, the use of atropine and dopamine After all returned to normal. No intraoperative and postoperative hemodynamics related cerebral hypoperfusion or hyperperfusion complications. Conclusion: Hemodynamic instability is a more common complication in CAS and can be controlled by drugs.
