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.
Abstract
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.Results ① There 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.③ 8 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.
