目的探讨超声血管增强技术(VET)在胎儿肺静脉超声检查中价值.方法根据孕龄将289例胎儿肺静脉分成A组(15～22周,89例)、B组(23～30周,152例)、C组(31～38周,48例),在不同孕龄组均应用二维超声心动图(2DE)、彩色多普勒血流显像(CDFI)、彩色多普勒能量图(CDE)、VET 4种方法进行对比分析,同时比较VET在不同孕龄组的应用情况.结果不同孕龄组胎儿4支肺静脉显示情况:A组89例中2DE显示11例(12.36％),CDFI显示38例(42.70％),CDE显示42例(47.19％),VET显示70例(78.65％),VET与2DE、CDFI、CDE比较肺静脉显示率明显增高(P＜0.05).B组152例中2DE显示36例(23.68％),CDFI显示75例(49.34％),CDE显示82例(53.95％),VET显示145例(95.39％),VET与2DE、CDFI、CDE比较肺静脉显示率明显增高(P＜0.05).C组48例中2DE显示16例(33.33％),CDFI显示30例(62.50％),CDE显示32例(66.67％),VET显示29例(60.42％),VET与2DE比较肺静脉显示率明显增高(P＜0.05),与CDFI、CDE比较肺静脉显示率差异无统计学意义(P＞0.05).VET在不同孕龄组中胎儿4支肺静脉显示情况比较:B组肺静脉显示率最高,明显高于A组(P＜0.05)、C组(P＜0.05),A组肺静脉显示率明显高于C组(P＜0.05).结论 VET可明显提高胎儿肺静脉的显示率,并能对肺静脉进行定位检查,胎儿肺静脉检查的最佳时间为中孕期.

Objective To investigate the ultrasound vascular enhancement technology(VET)in the ultrasound detection of fetal pulmonary vein.Methods According to gestational age,289 cases of fetal pulmonary vein were divided into group A(15 to 22 weeks,n =89),group B(23 to 30 weeks,n =152),group C(31 to 38 weeks,n =48).In these groups,VET technology,two-dimensional echocardiography (2DE),color Doppler flow imaging(CDFI),color Doppler energy(CDE)were simultaneously detected.VET technology Results were compared with the other three methods,and compared in different gestational age groups.Results Four fetal pulmonary veins in different groups of gestational week were displayed as following:In group A,2DE showed 11 cases(12.36％),CDFI 38 cases(42.70％),CDE 42 cases (47.19％),VET 70 cases(78.65％),compared with 2DE,CDFI and CDE,the positive rate of VET was significantly higher(P＜0.05).In group B,2DE showed 36 cases(23.68％),CDFI 75 cases(49.34％),CDE 82 cases(53.95 ％),VET 145 cases 95.39(％),compared with 2DE,CDFI and CDE,the positive rate of VET was significantly higher(P＜0.05).In group C,2DE showed 16 cases(33.33％),CDFI 30 cases (62.50 ％),CDE 32 cases(66.67 ％),VET 29 cases(60.42 ％),compared with 2DE,the positive rate of VET was significantly higher(P＜0.05);compared with CDFI and CDE,the positive rate of VET was no significant difference(P＞0.05).The display rate of four fetal pulmonary veins in group B was the highest,and the positive display rate in group A was significantly higher than in group C(P＜0.05).Conclusions VET can significantly improve the display rate of the fetal pulmonary vein,and locate inspection of fetal pulmonary vein.The best time for fetal pulmonary vein to check is the second trimester.
