超声心动图评价动脉导管未闭封堵术后心腔大小及左心功能

目的应用彩色多普勒超声技术观察动脉导管未闭封堵术后各心腔大小及左室收缩功能的变化,评价封堵术的效果。方法抽取2009年01月—2012年05月在笔者所在医院行动脉导管未闭封堵术的患者共31例,分别在术前2 d、术后1 d及术后1、3、6个月对患者进行常规超声多普勒心动图检查,观察右房横径(RAD1)、右房长径(RAD2)、右室前后径(RVD1)、右室横径(RVD2)、左房前后径(LAD1)、左房横径(LAD2)、左房长径(LAD3)、左室舒张末前后径(LVD1)、左室横径(LVD2)、左室射血分数(EF%)、左室短轴缩短率(FS%)、左室每搏量(SV)的变化。结果与术前比较,术后1 d、术后1、3、6个月LAD1、LAD2、LAD3、LVD1及LVD2逐渐减小,EF%、FS%、SV逐渐减小,以术后1 d、术后1个月及术后3个月为著;RAD1、RAD2、RVD1、RVD2无明显改变。结论封堵术作为一种简便、安全的治疗动脉导管未闭的微创手术方法,不仅可以减轻传统手术给患者带来的痛苦与风险,而且可以有效恢复心腔大小和改善左心收缩功能。

Echocardiography for evaluating changes of heart chambers and left ventricular function after transcatheter closure of patent ductus arteriosus

Objective To observe the changes of heart chambers and left ventricular systolic function after transcatheter closure of patent ductus arteriosus by color Doppler ultrasound,evaluate transcatheter closure effect. Methods The 31 cases subjected to transcatheter closure of patent ductus arteriosus from Jan 2009 to May 2012 in author＆#39;s hospital,respectively at two days before operation,and one day,one month,three months,and 6 months after operation received general check by echocardiography. The changes in right atrium cross diameter （RAD1）, right atrium long diameter（RAD2）,right ventricular anteroposterior diameter（RVD1）,right ventricular cross diameter （RVD2）,left atrium anteroposterior diameter （LAD1）,left artium cross diameter （LAD2）,left atrium long diameter （LAD3）,left ventricular diastole anteroposterior diameter（LVD1）,left ventricle cross diameter（LVD2）,left ventricular ejection fraction （EF%）,left ventricular fractional shortening （FS%） and left ventricular stroke volume （SV） were observed. Results Compared with that before operation,at one day,one month,three months and six months after operation,LAD1,LAD2,LAD3,LVD1 and LVD2 gradually reduced,EF%,FS%,SV gradually reduced,especially at one day,one month and three months after operation. RAD1,RAD2,RVD1,RVD2 didn＆#39;t have any significant changes. Conclusion Transcatheter closure of patent ductus arteriosus as a simple,safe and non-invasive procedure,can reduce the pain and risk of patients in the traditional operation,effectively regain heart chambers size,and improve of left ventricular systolic function.
