摘要
目的探讨实时三维超声心动图(RT-3DE)联合三血管气管切面(3VT)诊断胎儿先天性心血管畸形的特异性研究。方法对1000例高危孕妇行常规胎儿心动图的RT-3DE联合3VT切面检查,重点观察心脏大血管的形态、结构、连接关系,以及血流动力学情况。结果胎儿RT-3DE联合3VT切面诊断胎儿先天性心血管畸形发病率2.8%(28/1000)、特异性93%、敏感性91%、阴性预测值94%、阳性预测值92%,与二维超声相比,RT-3DE联合3VT切面的超声解剖更具有特征性。结论 RT-3DE联合3VT切面对诊断胎儿先天性心血管畸形特异性高,可作为孕妇的常规检查。
Objective To explore the clinical value of real -time three -dimensional echocardiography (RT- 3DE) combined with three vessels and trachea view (3VT) in diagnosis of fetal congenital cardiovascular anomaly. Methods One thousand pregnant women with high risk factors underwent fetal RT -3DE combined with 3VT examination. The shape, structure, connection relationship and hemodynamlc of cardiac vessels were observed. Results The incidence of congenital cardiovascular anomaly diagnosed by RT -3DE combined with 3VT was 2.8% , the specificity, sensitivity, positive predicted value and negative predicted value were 93%, 91%, 94% and 92% , respectively. Compared with two - dimensional uhrasound, RT - 3DE combined with 3VT posses more specificity in ultrasonic anatomy. Conclusion RT - 3DE combined with 3VT has high specificitv in diagnosis of fetal congenital cardiovascular anomalv, it can be used as a routine examination for laregnant women.
