摘要
目的 探讨“顺序分段法”提高胎儿心脏超声的宫内先天性心脏病 (先心病 )诊断的准确率。 方法 首先确定心脏位置及心胸比例 ,将胎儿心脏分为 4个节段 (心房、心室、大血管及血管交叉、主动脉弓和动脉导管弓 )筛查及诊断先心病 ,同时对每例胎儿进行外周动、静脉多普勒血流检测 ,评价先心病对外周血流动力学及胎儿生长发育的影响。 结果 1470例胎儿中检出先心病 45例 ,其中复杂性心血管畸形 19例、心功能降低 13例、6例胎儿水肿及大量心包积液 ,合并心律失常 7例 ,外周血流搏动指数 (PI)与正常组差异有显著性 (P<0 .0 1)。 结论 胎儿心脏超声“顺序分段法”可明显提高先心病的检出率及诊断准确率 ,特别有利于在产前低危人群中的筛查。
Objective\ To investigate and establish the method that examine the fetal heart with fractional method in order, which can elevate the accuracy in diagnosing the congenital heart disease(CHD).\ Methods\ The heart position and cardio\|thorax ratio were located and determined firstly.\ Then the fetal heart examination were separated into four fractions(atrium, ventricle, great vessels and the crossed relation of aorta and pulmonary artery, the aortic arch and ductus arteriosus) in distinguishing the CHD.\ The peripheral Doppler blood flow value in each fetus and the effect of CHD to the peripheral blood flow were examined and evaluated at last.\ Results\ There were forty two cases of CHD in 1450 examined fetuses, which included seventeen fetuses of complex cardiovascular malformation, thirteen fetuses of heart function degression, five fetuses of cardiac edema and pericardial edema, seven fetuses of arrhythmias, in CHD cases the pulse index(PI) value was significantly different from that of the normal.\ Conclusion\ A method of fractional examination in order is used in diagnosing fetal CHD, especially in low\|risk antepartal gravida.\ It can elevate the accuracy in diagnosing CHD.\;
