摘要
目的:总结胎儿期左位下腔静脉及双下腔静脉的超声声像图特征。方法:回顾性分析于浙江大学医学院附属妇产科医院行超声检查显示左位下腔静脉(18例)和双下腔静脉胎儿(16例)的临床资料及超声图像表现,总结其特征。结果:左位下腔静脉超声表现为胎儿上腹部横切面下腔静脉和腹主动脉位置表现正常,即下腔静脉位于腹主动脉右前方;而于肾门水平下方下腔静脉位于腹主动脉左后方,于肾门水平跨越腹主动脉前方,向右上方斜行,形成右侧的下腔静脉,最后流入右心房。双下腔静脉超声表现为胎儿下腹部横切面脊柱前方见三根血管横断面。腹部冠状切面腹主动脉两侧均见静脉伴行,并均延续自同侧髂静脉。34例下腔静脉异常胎儿中,合并其他系统异常17例,其中心脏异常13例。结论:左位下腔静脉和双下腔静脉有典型产前超声表现,产前超声容易诊断。左位下腔静脉和双下腔静脉常合并其他系统异常(尤其是心脏畸形),须仔细排查。
Objective: To evaluate the application of ultrasonography in prenatal diagnosis of left inferior vena cava and double inferior vena cava in fetus. Methods: The clinical data and ultrasonographic findings of the fetuses with left inferior vena cava (18 cases) or double inferior vena cava (16 cases) were retrospectively analyzed. Results: The ultrasonographic images of left inferior vena cava showed that in the transverse view of the fetal upper abdomen the inferior vena cava and abdominal aorta were in the normal position;below the level of the hilum, the inferior vena cava was located behind the left side of the abdominal aorta;at the level of the hilum, it crossed the front of the abdominal aorta and run diagonally to the upper right, forming the right inferior vena cava and finally entered into the right atrium. The ultrasonographic images of double inferior vena cava showed that in the transverse view of the fetal lower abdomen, in front of spine there were three transections of blood vessels;in coronal plane of abdomen, the veins run on both sides of the abdominal aorta and entered to the iliac vein of the same side. In 34 cases of abnormal inferior vena cava, there were 17 cases complicated with other system abnormalities, including 13 cases of cardiac anomalies. Conclusions: The left inferior vena cava and double inferior vena cava have characteristic imaging findings, and prenatal diagnosis can be made with ultrasonography. This type of congenital deformity is frequently complicated with other system abnormalities, which should be excluded in fetus, especially for heart system.
