目的总结胎儿冠状静脉窦扩张的超声心动图表现,分析胎儿冠状静脉窦扩张的原因。方法回顾性总结94例产前超声诊断为胎儿冠状静脉窦扩张的超声心动图表现,及分析胎儿冠状静脉窦扩张的原因,并于产后行超声心动图检查或引产后行尸体解剖随访对照。结果 94例冠状静脉窦扩张胎儿中,64例为冠状静脉窦扩张仅伴永存左上腔静脉;26例为冠状静脉窦扩张伴永存左上腔静脉及其他心内畸形(如右侧异构、主动脉缩窄等);2例冠状静脉窦扩张仅伴心内型完全性肺静脉异位引流;1例冠状静脉窦扩张仅伴三尖瓣下移畸形;1例单纯冠状静脉窦扩张,未发现其扩张原因。94例冠状静脉窦扩张胎儿中引产后病理或产后超声心动图证实74例。结论产前超声对确诊胎儿冠状静脉窦扩张及分析其扩张原因,具有重要诊断价值和临床意义。
Objective To summarize the echocardiographic findings of fetal coronary sinus dilatation and analyze the causes of fetal coronary sinus dilatation. Methods A retrospective review of 94 cases of prenatal ultrasound diagnosis of fetal coronary sinus dilatation echocardiography, and analysis of fetal coronary sinus dilatation causes and postpartum echocardiography or postpartum autopsy follow-up control. Results Among the 94 cases of coronary sinus dilatation, 64 cases were coronary sinus dilatation only with the presence of the left superior superior vena cava; 26 cases were coronary sinus dilatation with the presence of the left superior superior vena cava and other intracardiac malformations (eg right anterior isomerism, aorta Narrowing, etc.); 2 cases of coronary sinus dilatation with only type of complete anomalous pulmonary venous drainage; 1 case of coronary sinus dilatation only with tricuspid regurgitation; 1 case of coronary sinus dilatation, did not find its expansion the reason. A total of 74 cases were confirmed by postnatal pathology or postnatal echocardiography in 94 cases of coronary sinus dilation fetus. Conclusions Prenatal ultrasound is an important diagnostic value and clinical significance for the diagnosis of fetal coronary sinus dilatation and analysis of the reasons for its expansion.
