三血管切面诊断胎儿大血管异常的价值

The valve of three-vessel view diagnosis fetal great arteries abnormity

目的探讨三血管切面诊断胎儿心底部大血管异常的价值。方法采用彩色多普勒超声常规检查胎儿心脏的四腔心切面及左右流出道长轴切面等,再以四腔心切面为基础,向胎儿头侧平行侧移连续扫查,显示三血管短轴切面,观察主、肺动脉、上腔静脉及动脉导管等结构,明确心底部大血管的数目、连接关系、走行及内径。结果经本血管切面确诊的大血管异常35例,其中永存动脉干6例、肺动脉狭窄5例、肺动脉闭锁3例、主动脉狭窄2例、动脉导管狭窄5例、动脉导管走行异常3例、大动脉转位5例、右室双出口3例、永存左上腔静脉3例。经尸检或产后复诊,畸形结果与产前诊断相符。结论三血管切面超声检查对筛查及诊断胎儿心脏大血管畸形的先天性心脏病有重要的价值。

Objective Discuss the valve of three-vessel view diagnosis fetal great arteries abnormity Methods Use Color Doppler Flow Image sonography general examine the four chamber view and left-right ventricular outflow track long Axis view,To the basis of four chamber view,To fetal head side parallel move continue scan,display three-vessel short Axis view,observed aorta,pulmonary artery,superior vena cava and patent ductus,defmitude heart base,the number of great arteries,connect relation,track and diameter.Results By the three-vessel view diagnosis great arteries abnormity 35 case,among persistent trunkus arterious 6 case,pulmonary artery stenosis 5 case,pulmonary stenosis 3 case,aortic stenosis 2 case,patent ductus stenosis S case,patent ductus track abnormity 3 case,transposition of great arteries 5 case,double outlet right ventricle 3 case,persistent left superior vena cava 3 case.By autopsy and postpartum referral,abnormity result match with prenatal diagnosis.Conclusions It is important valve use three-vessel view echocardiogram to examine and diagnosis fetal congenital heart and great arteries deformity.
