目的:探讨产前彩色多普勒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7例胎儿永存左上腔静脉的超声图像,总结胎儿永存左上腔静脉各切面异常声像图特点并结合文献探讨其超声诊断价值。结果:超声诊断的7例胎儿永存左上腔静脉均为Ⅰ型,引流入冠状静脉窦。1例合并染色体异常,余6例均未合并其他心脏畸形。结论:胎儿永存左上腔静脉图形有特定的特征,超声是诊断永存左上腔静脉的首选方法,具有重要临床意义。
Objective: To investigate the clinical value of prenatal color Doppler ultrasound in the diagnosis of fetal left anterior superior left ventricular. Methods: Seven cases of fetal left anterior superior vena cava ultrasonography were retrospectively analyzed. The characteristics of fetal left anterior superior vena cava anomalies were summarized and the diagnostic value of ultrasound was analyzed. Results: Ultrasound diagnosis of 7 cases of fetal left anterior superior left vena cava are type Ⅰ, drainage into the coronary sinus. One patient had combined chromosomal abnormalities, and the other 6 patients did not have other cardiac malformations. CONCLUSION: Fetal perpetuated left superior vena cava has certain characteristics. Ultrasound is the first choice for the diagnosis of the left ventricular superior vena cava. It has important clinical significance.
