摘要
目的探讨胎儿左无名静脉异常的超声诊断线索及临床意义。方法回顾性分析2012年1月至2023年4月于广东省妇幼保健院超声诊断胎儿左无名静脉异常的类型,总结超声诊断线索。结果①10例胎儿左无名静脉异常(left brachio-cephalic vein,LBCV)中3例(30%)主动脉弓下LBCV,2例(20%)食管后LBCV,1例(10%)胸腺内LBCV,4例(40%)左无名静脉增宽。②3例主动脉弓下LBCV中1例伴巨细胞病毒感染,引产;2例食管后LBCV中1例合并复杂畸形,引产;1例胸腺内LBCV未合并其他结构异常;4例无名静脉增宽中2例合并血管畸形,2例合并轻微异常。③8例胎儿出生,情况良好。结论不同类型异常胎儿左无名静脉具有特征性的超声征象,产前区分无名静脉异常类型具有重要的临床意义。
Objective To investigate the ultrasound diagnostic clues and significance of anomalous fetal Left Brachiocephalic Vein(LBCV).Methods The types of anomalous fetal LBCV were retrospectively analyzed and ultrasound diagnostic clues were summarized.Results①There were 10 cases of abnormal LBCV,of which 3 cases(30%)were subaortic LBCV,2 cases(20%)were posterior esophageal LBCV,1 case(10%)were intrathymic LBCV,and 4 cases(40%)were LBCV widening.②Among 3 cases of subaortic LBCV,1 case was accompanied by cytomegalovirus infection and induced labor;Among 2 cases of posterior esophageal LBCV,1 case was complicated with malformation and induced labor;1 case of intrathymic LBCV without other structure abnormalities;Among 4 cases of LBCV widening,2 cases had vascular malformations and 2 cases had mild abnormalities.③8 cases were born and showed good growth.Conclusion Different types of abnormal LBCV have characteristic Ultrasonic features.Distinguishing the types of abnormal LBCV before delivery has important clinical significance.
