摘要目的 探讨产前超声诊断胎儿永存左上腔静脉的临床价值.方法 回顾性分析21例经胎儿超声检查诊断为永存左上腔静脉的超声资料与随访结果,分析总结胎儿永存左上腔静脉各切面异常声像图特点.结果 12例胎儿经尸体解剖证实为永存左上腔静脉,胎儿永存左上腔静脉的主要声像图特征是胎儿心脏三血管切面观,肺动脉左侧多一条血管.冠状静脉窦扩张有助于诊断.结论 产前超声检查是诊断永存左上腔静脉的首选方法,有重要临床意义.

abstractsObjective To investigate the clinical value of prenatal diagnosis of fetal persistent left superior vena eava(PLSVC)with fetal echocardiography.Methods The data of 21 fetuses diagnosed as PLSVC by fetal echocardiography were reviewed and the abnormal echocardiographic features in various sonographic views were analyzed.Results Twenty fetuses were confirmed to be PLSVC by autopsy.The key echocardiographic features of PLSVC were demonstrated to:the presence of an additional vesselidentified to the left of the pulmonary artery in the three-vessel view of the heart.Coronary sinus dilation were helpful to the diagnosis.Conclusions Fetus PLSVC can be detected by echocardiography,which can contribute to cardiovascular catheterization and operation after birth.
