摘要
目的探讨血管回声跟踪技术在评价子痫前期孕妇颈总动脉弹性功能中的应用价值。方法对22例非妊娠期妇女(A组),24例健康妊娠晚期妇女(B组),19例轻度子痫前期孕妇(C组)和21例重度子痫前期孕妇(D组)进行双侧颈总动脉血管弹性指标[压力应变弹性系数(Ep)、硬度指数(β)、顺应性(AC)、脉搏波传导速度(PWVβ)及膨大指数(AI)]及内膜厚度(IMT)的测量,并进行统计学分析。结果与A、B组比较,C组和D组患者双侧颈总动脉Ep、β、PWVβ级AI均升高,差异有统计学意义(P<0.01);而颈总动脉内中膜厚度虽有所增加,但差异无统计学意义(P>0.05)。结论血管回声跟踪技术可以早期发现子痫前期孕妇颈总血管弹性变化。
Objective To investigate the application value of echo tracking technique for assessing the elasticity of general carotid artery in pre-eclamptic pregnant women. Methods The vascular elastic indexes,such as the elasticity modulus （Ep）, stiffness parameter （ β ）, arterial compliance （AC）, augmentation index （AI） and one-point wave velocity （ PWV 13 ）, and inti mal-media thickness （IMT） of bilateral common carotid arteries were detected in 22 non-pregnant women （A）, 24 normal pregnant women in the late trimester pregnancy （B）, 19 pregnant women with mild preeclampsia （C）and 21 pregnant women with severe preeclampsia （D）.Then the detected dada were analyzed statistically. Results Compared with the group A and B, the group C and D had higher values of Ep, β, AI and PWVI3 in bilateral common carotid arteries and the values of AC were lower, the differencee showing statistical significance（P〈0.01 ）.Although the IMT of bilateral common carotid arteries in the group C and D was higher than that of in group A and group B, however,there was no statistical difference （P〉0.05）. Conclusion The echo tracing technique can find the early changes of elasticity of bilateral common carotid arteries in pre-eclamptic women.
