摘要
目的:探讨血管回声跟踪(E-Tracking,ET)技术评价晚期妊娠妇女双侧颈动脉顺应性改变的价值。方法:对正常妊娠女性35例(妊娠组)和该年龄段的非妊娠女性35例(对照组),应用ET技术检测双侧颈总动脉的硬化度(β)、弹性系数(Eρ)、动脉顺应性(AC)、膨大系数(AI)及单点脉搏波传导速度(PWVβ),并比较其差异。结果:妊娠组β、Eρ、AI、PWVβ与对照组比较明显升高,AC降低(P<0.05,P<0.01)。结论:血管回声跟踪技术能够简便、准确地反映妊娠血管内皮功能的变化。
Objective：To investigate the echo-tracking（E-Tracking, ET） technical in evaluating carotid artery elasticity in late pregnancy. Methods：35 female cases of normal pregnancy were selected as pregnancy group, and 35 non-pregnant female cases of child-beating age were selected as control group. The stiffness parameter（β）,elastic eoefficient（Ep）,arterial compliance （AC）, augment index （AI）, and one point pulse wave velocity （PWVβ） of bilateral common carotid artery were measured by ET techniques. Results：β, Ep,AI,PWVβ were significantly higher in pregnancy group than those in control group,meanwhile AC was lower （P〈0.05 ,P〈0.01）. Conclusion：Vascular echo-tracking technology can precisely reflect vascular endothelial function changes of pregnancy. This method is easy and feasible.
