震荡生理盐水微气泡显影试验在儿科心脏病超声诊断中的应用

Agitated saline contrast echocardiography in pediatric cardiology

目的通过概述临床上应用震荡生理盐水微气泡显影试验(saline contrast echocardiography,SCE)来评估小儿先天性和获得性心脏病的经验。方法对竹脚妇幼医院儿童心脏中心20年来曾使用震荡生理盐水微气泡超声显影试验的典型病例进行回顾,并通过文献复习来总结应用该技术的经验。结果以7例患者的实例阐述了以SCE作为标准彩色超声心动图的辅助手段,不但可用于描述心外和心内右至左分流,也可以增强心肌-血液界面,从而延伸出其他用途。结论SCE是标准彩色超声心动图检查的一项非常有用的辅助技术。该技术简单,易操作,很容易在床旁应用。尤其对具挑战性诊断问题的小儿患者,这项检查对厘清诊断很有帮助。

Objective To outline our experience with the use of saline contrast echocardiography(SCE)in the evaluation of paediatric patients with congenital and acquired heart disease.Methods We have reviewed current literature and the range of cases for which we have used SCE over 20 years period in Cardiology Service,Department of Paediatric Subspecialties,KK Women's and Children's Hospital,and specific cases were used to illustrate our experience with this technique.Results We describe the use of SCE as an adjunct to standard echocardiography in 7 cases.We have found this technique useful in demonstrating extracardiac and intracardiac right to left shunts,and in enhancing myocardial-blood interface.Conclusion Agitated SCE is a useful adjunctive technique to standard echocardiography that is readily applied at the bedside and has been helpful,in our experience,in the work-up of paediatric patients with challenging diagnostic cardiac problems.
