目的探讨胎儿永存左上腔静脉的产前超声声像图特征,提高对胎儿永存左上腔静脉的诊断。方法回顾性分析2007-01-2010-01在湖南省妇幼保健院产前超声检查诊断为胎儿永存左上腔静脉的121例胎儿超声图像表现,并且将超声检查结果与手术病理及产后临床其他检查结果对照,评价胎儿永存左上腔静脉的超声特征。结果在产前超声诊断为永存左上腔静脉121例胎儿中经手术病理及产后临床其他检查确诊为永存左上腔静脉112例,3例误诊,6例未追踪到结果被排除在本研究之外。产前超声诊断胎儿永存左上腔静脉准确率为97%(112/115),误诊率为3%(112/115)。结论产前超声对胎儿永存左上腔静脉诊断有较高的诊断敏感性及准确性。
Objective To investigate the characteristics of fetal prenatal ultrasonography of the left superior vena cava and to improve the diagnosis of the left anterior superior left ventricular in the fetus. Methods A retrospective analysis of 121 fetuses with fetal left anterior superior vena cava diagnosed by prenatal ultrasound in Hunan Provincial Maternal and Child Health Hospital from January 2007 to October 2010 was performed. The ultrasonographic results were compared with the results of surgery, pathology and other postnatal clinical findings Control, evaluate the fetal left anterior superior left ventricular ultrasonographic features. Results In prenatal diagnosis of 121 cases of fetal left anterior superior left ventricle by pathology and other postpartum clinical examination confirmed the permanent left superior vena cava 112 cases, 3 cases were misdiagnosed, 6 cases were not tracked to the results were excluded from the study. The accuracy of prenatal diagnosis of fetal left anterior superior vena cava was 97% (112/115), with a misdiagnosis rate of 3% (112/115). Conclusion Prenatal ultrasound has a higher diagnostic sensitivity and accuracy in the diagnosis of fetal left anterior superior vena cava.
