目的探讨超声四切面法在胎儿左室发育不良筛查诊断中的临床价值。方法本研究于2013年1月至2014年12月采用超声四腔心切面、左室流出道切面、右室流出道切面和三血管切面的“四切面”法快速筛查胎儿心脏,再叠加彩色多普勒血流显像,观察各房室及大动脉血流分布和血流方向。结果共筛查2013年1月~2014年12月孕18-24w的胎儿20000例,发现胎儿左室发育不良10例,其中伴主动脉狭窄4例,伴二尖瓣闭锁6例,二尖瓣闭锁中伴右室双出口及室间隔缺损4例。结论 “四切面”法简单,易掌握,重复性好,对产前筛查胎儿左室发育不良具有重要的临床价值,值得在广大的基层医院推广应用。
Objective To investigate the clinical value of four-slice ultrasound in the screening of fetal left ventricular dysplasia. METHODS: From January 2013 to December 2014, we performed rapid screening of the fetal heart using the four-chamber echocardiography, the left ventricular outflow tract, the right ventricular outflow tract and the three-vessel cross-section Superposition of color Doppler flow imaging, observation of atrioventricular and aortic flow distribution and blood flow direction. Results A total of 20,000 fetuses of 18-24 weeks pregnant from January 2013 to December 2014 were enrolled in this study. Ten cases of fetal left ventricular dysplasia were found, including 4 cases with aortic stenosis, 6 cases with mitral atresia, Locked with right ventricle double outlet and ventricular septal defect in 4 cases. Conclusion The method of “four aspects” is simple, easy to master and has good repeatability. It has important clinical value for prenatal screening fetal left ventricular dysplasia and is worth popularizing and applying in the vast primary hospitals.
