目的探讨永存左上腔静脉胎儿超声心动图特征及临床意义。方法对诊断为永存左上腔静脉的17例胎儿超声心动图表现进行回顾分析,17例永存左上腔静脉胎儿中引产后病理及产后超声心动图证实,总结永存左上腔静脉胎儿超声心动图各切面声像图特点及临床价值。结果 17例超声表现为:四腔切面可见扩张的冠状静脉窦,三血管切面在肺动脉左侧可见永存左上腔静脉一圆形血管回声,追踪走行可见其与冠状静脉窦相连接。其中10例为单发畸形(10/17,58.82%),7例合并其他畸形(4例合并心内畸形、2例合并心外畸形、1例同时合并心内和心外畸形)。结论胎儿超声心动图对诊断永存左上腔静脉有较高的准确性和临床价值。
Objective To investigate the characteristics and clinical significance of fetal echocardiography in the left superior superior vena cava. Methods A retrospective analysis of 17 cases of fetal echocardiography diagnosed as perpetuating left superior vena cava was performed. 17 cases of permanent left superior vena cava fetal induction of postpartum pathology and postnatal echocardiography were confirmed. The echocardiographic aspects of left anterior superior left ventricular Pictorial features and clinical value. Results Seventeen cases of ultrasound showed that the dilated coronary sinus could be seen in the four-chamber view. The left ventricle of the three vessels showed a round echogenic eternal of the left superior vena cava in the left side of the pulmonary artery, and its connection to the coronary sinus was observed. Among them, 10 were single deformities (10/17, 58.82%), 7 were associated with other deformities (4 with intracardiac deformity, 2 with extracardiac deformity and 1 with combined intracardiac and extracardiac deformities). Conclusion Fetal echocardiography has a higher accuracy and clinical value in the diagnosis of perpetual left superior vena cava.
