颈动脉支架成形术血流动力学损害的相关因素分析

目的：分析颈动脉支架成形术后造成血流动力学损害的相关因素。方法：回顾分析66例（71处病变）接受颈动脉支架成形术患者围手术期血流动力学损害的相关因素。结果：71例次颈动脉支架成形术中，血流动力学损害发生率为32.4%（23/71），其中低血压发生率为11.3%。单因素分析显示，病变距离颈动脉分叉的距离（P=0.002 0）、斑块分布（P=0.000 2）、斑块性质（P=0.001 9）和后扩张（P=0.002 6）与血流动力学损害有关，然而多因素分析中只有偏心斑块(P=0.015 3)和钙化斑块(P=0.009 7)与血流动力学损害相关。所有病例在术中通过药物治疗即能达到循环稳定，无围手术期短暂性脑缺血事件及卒中事件，无围手术期心血管缺血事件。结论：病变与分叉部的距离、偏心斑块、钙化斑块是血流动力学损害的相关危险因素。

Related factors of hemodynamic damage after carotid artery stenting

Objective:To analyze correlation factors of hemodynamic damage after carotid artery stenting.Methods:In this study, 66 cases (71 lesions) who undertook carotid artery stenting were col-lected and the correlation factors of hemodynamic damage were analyzed .Results:Hemodynamic damage emerged in 23 cases (32.4%), of which, 11.3%developed hypotension.The distance between bifurca-tion and lesions (P=0.002 0), plaque distribution (P=0.000 2), plaque character (P=0.001 9), post-dilation ( P =0.002 6 ) were associated with hemodynamic damage by single factor analysis . However, only eccentric plaque (P=0.015 3) and calcified plaque (P=0.009 7) were associated with hemodynamic damage by multiple factors analysis .All the patients could reach stable circulation by drugs during operation , and no cerebral ischemic events ( transient ischemic attack or stroke ) and cardiovascu-lar ischemic events happened .Conclusion: The distance between bifurcation and lesions , eccentric plaques, calcified plaques are correlation factors of hemodynamic damage .
