摘　　要：目的探讨超声斑点追踪显像技术对动脉导管未闭(PDA)封堵前后心脏旋转运动的意义。方法统计分析2013年5月至2016年5月我院收治的50例PDA患者的临床资料。结果组内比较,研究组患者术后的舒张期末左室内径(LVEDD)显著短于术前(P<0.05),左室舒张末容积(LVEDV)显著小于术前(P<0.05),但手术前后左室射血分数(LVEF)之间的差异无统计学意义(P>0.05);组间比较,术前研究组患者的LVEDD显著长于对照组(P<0.05),LVEDV显著大于对照组(P<0.05),但2组患者的LVEF之间的差异均不显著(P>0.05),术后两组患者的LVEF,LVEDD,LVEDV之间的差异无统计学意义(P>0.05);2组人员手术前后左心室基底段,中间段,心尖段旋转角度峰值,扭转角度峰值之间的差异无统计学意义(P>0.05)。结论超声斑点追踪显像技术能够有效评价PDA封堵前后心脏旋转运动。Objective To evaluate the significance of ultrasound speckle tracking imaging on cardiac rotational movement before and after PDA closure. Methods The chnical data of 50 cases of patients with PDA in our hospital from May 2013 to May 2016 were statistically analyzed. Results Comparation within groups, the postoperative LVEDD of the study group was significantly shorter （P〈0.05）, the former LVEDV was significantly less than before surgery （P〈0.05）, but the difference of LVEF between before and after surgery was not significant （P〉0.05）; Compara- tion between groups, the preoperative LVEDD of the the study group significantly longer （P〈0.05）, the LVEDV was significantly greater than the control group （P〈0.05）, but the difference of LVEF between the two groups was not sig- nificant （P〉0.05） The differences of LVEF, LVEDD, LVEDV after surgury between the two groups were not significant （P〉 0.05）; the differences of left ventricular basal segments, the middle section, apical segment rotation angle peak be- tween torsion angle peaks before and after surgery between the two groups were not significant （P〉0.05）. Conclusion ultrasound speckle tracking imaging can effectively evaluate the cardiac rotational movement before and after PDA closure.
