永存左侧上腔静脉的产前超声诊断及畸形分析
Prenatal diagnosis of persistent left superior vena cava and its anatomic features
摘要
Abstract
Aim:To analyze sonographic features of persistent left superior vena cava ( PLSVC) of fetuses and its car-diac and extracardiac anomalies .Methods:A total of 25 737 sonographic and echocardiographic data of fetuses were retro-spectively studied .When a supernumerary vessel left of the pulmonary trunk showed on three-vessel view , it would be scaned on long-axis view.Results:A total of 67 cases of PLSVC were detected , which was showed as an additional vessel identified to the left pulmonary artery on three-vessel view and drainage via the coronary sinus into atrium on long-axis view. The congenital heart defect rates were significantly different between fetuses with and without PLSVC (χ2adjust =955.968,P<0.001)and the anomalous connection of vein rates were also significantly different (P<0.001).Between fetuses with and without PLSVC the atrial isomerism rates were also different (χ2adjust=84.223, P<0.001).Among fetuses with PLSVC, the most common cardiac malformations in those with atrial isomerism were atrioventricular septal defect and double right ventri -cle outlets, while the common most congenital heart defects in those without atrial isomerism were ventricular septal defect , conotruncal defect and coarction .Conclusion:The three-vessel view and long-axis vein view are the best diagnostic planes of PLSVC.PLSVC has greater prevalence in fetuses with congenital heart defects , especially with atrial isomerism and ve-nous anomaly cases .关键词
