目的采用增强型血流成像技术(e-Flow)显示并定位4条肺静脉,为胎儿心脏畸形的诊断和风险评估提供可靠依据。方法选取2010年6～12月在我院行胎儿超声心动图检查的200例胎儿,孕妇孕龄为20～40周,根据成人肺静脉定位方法,应用e-Flow技术对胎儿不同切面的4支肺静脉进行观察。结果 200例胎儿超声心动图显示及定位肺静脉图像满意。左上肺静脉在胸部横切面显示四腔心及降主动脉时,距离降主动脉较远,斜行进入左心房。左下肺静脉在胸部横切面显示四腔心及降主动脉时,紧邻降主动脉,垂直进入左心房;主动脉弓切面,左下肺静脉与降主动脉胸段呈90°角,走行于降主动脉前方,垂直进入左心房。右上肺静脉在胸部横切面显示四腔心时,紧邻右心房顶部走行,在上腔静脉左侧进入左心房。胸部横切面显示四腔心,右下肺静脉较右上肺静脉距离脊柱更近,平行于房间隔水平进入左心房。结论 e-Flow技术可以显示胎儿4条肺静脉,并能对肺静脉进行定位。
Objective To display and locate 4 pulmonary veins by enhanced flow imaging (e-Flow), which provides a reliable basis for the diagnosis and risk assessment of fetal cardiac malformations. Methods 200 fetuses with fetal echocardiography in our hospital from June to December in 2010 were enrolled in this study. The gestational age of pregnant women was 20 to 40 weeks. According to the method of pulmonary vein localization in adult, Observe. Results 200 cases of fetal echocardiography and location of pulmonary vein images satisfactory. Left upper pulmonary vein in the chest cross-section shows four-chamber heart and descending aorta, the distance from the descending aorta, oblique into the left atrium. Left lower pulmonary vein in the thoracic transverse plane shows the four chambers of the heart and descending aorta, immediately adjacent to the descending aorta, vertical into the left atrium; aortic arch section, lower left pulmonary vein and descending aorta was 90 ° angle, walking in front of the descending aorta, vertical Into the left atrium. Right superior pulmonary vein in the chest cross-section shows four-chamber heart, near the top of the right atrium walk, left in the superior vena cava into the left atrium. Chest cross-section shows four-chamber heart, right lower pulmonary vein more right superior pulmonary vein closer to the spine, parallel to the atrial septal level into the left atrium. Conclusion The e-Flow technique can display 4 pulmonary veins of the fetus and locate the pulmonary veins.
