| 目的 探讨早孕期胎儿静脉导管异常的超声表现及其预后。方法 回顾性分析我院早孕期超声检出26例胎儿静脉导管异常的超声图像特点，记录静脉导管结构、走行及脐静脉连接，并追踪随访其预后。结果 26例为静脉导管缺如，其中4例脐静脉汇入下腔静脉，2例脐静脉汇入右房，1例脐静脉汇入左房，3例门-肝静脉分流，16例脐静脉汇入门静脉。静脉导管缺如表现为上腹部各切面均未显示静脉导管入膈下前庭，正常的脐静脉-左门静脉-静脉导管-下腔静脉之间的序贯连接关系消失，脐静脉绕过肝脏形成脐静脉肝外异位连接或肝内分流。7例同时合并心内外结构异常，8例合并心外结构异常，2例合并心脏结构异常，9例未合并其他结构异常。1例18-三体，1例21-三体。14例引产，9例出生后暂未见明显异常,1例出生后行室间隔缺损修补术后生长发育缓慢，2例失访。结论早孕期可以诊断大部分类型的静脉导管异常，但需要超声密切随访并进一步确诊，其预后主要取决于是否合并心内外畸形以及染色体异常。 |

| Abstract: |
| ABSTRACT Objective To explore the ultrasound manifestations and prognosis of fetal ductus venosus abnormalities in early pregnancy.Methods : Retrospective review of 26 fetuses with ductus venosus abnormalities diagnosed by ultrasonography during early pregnancy in our hospital . Ductus venosus structure ,umbilical vein connection ,and fetal outcomes were recorded. Results 26 cases were found with absence of ductus venosus, In 4 cases of umbilical vein connected to the inferior vena cava, 2 cases of umbilical vein connected to the right atrium, 1 case of umbilical vein connected to the left atrium, 3 cases of portal-hepatic vein shunt, 16 cases of umbilical vein connected to the portal vein . The absence of ductus venosus showed that there was no ductus venosus entering the inferior phrenic vestibule in each section of the upper abdomen, the sequential connection of the umbilical vein-left portal vein-ductus venosus -inferior vena cava disappeared, and the umbilical vein bypassed the liver to form extrahepatic ectopic connection or intrahepatic shunt.7 cases had intracardiac and extracardiac abnormalities, 8 cases had extracardiac abnormalities , 2 cases had intracardiac abnormalities，9 cases without other structural abnormalities. 1 case of 18 trisomy syndrome, 1case of 21 trisomy syndrome.14 cases of induced labor, and 9 cases showed no abnormality after birth, 1 case underwent repair of ventricular septal defect after birth, the growth and development was slow after operation, and 2 cases were lost to follow-up. Conclusions Most types of ductus venosus abnormalities can be diagnosed in early pregnancy, but it needs close follow-up and further diagnosis by ultrasound. The prognosis mainly depends on The prognosis mainly depends on malformations and chromosomal abnormalities. |
