Sonograms obtained during the 32nd and 34th weeks of a pregnancy complicated by severe Rh isoimmunization demonstrated features diagnostic of fetal-hydrops-scalp and body wall edema, ascites, hepatosplenomegaly and placental enlargement. The earliest sign that can be detected sonographically is placental enlargement.
在一例并发严重Rh血型免疫的妊娠中,于第32周和第34周获得的超声图显示出胎儿水肿的诊断特征——头皮和体壁水肿、腹水、肝脾肿大及胎盘增大。超声检查所能检测到的最早征象是胎盘增大。
