产前超声诊断19例胎儿内脏方位异常

Prenatal ultrasound diagnosis of 19 cases of fetal visceral azimuth abnormality

目的探讨产前超声诊断胎儿内脏方位异常,理清在检查过程中应该注意的检查手法及切面。方法回顾分析产前超声诊断的19例胎儿内脏方位异常的声像图资料。结果 8例为完全性内脏反位,其中2例完全性内脏反位伴先天性心脏病,1例不完全内脏反位,10例内脏异位:4例右房异构;6例左房异构。讨论首先准确判断宫内胎儿方位及姿势,在诸多切面中胎儿四腔心切面及腹部胃泡切面在胎儿内脏反位诊断中比较重要,检查过程中注意腹主动脉及下腔静脉的位置及关系,同时注意心房心室的左右区分。
