Normal levels of unconjugated estriol and human placental lactogen hormone in the maternal serum and a normal, reactive pattern of non-stress test cardiotocography were recorded in a case of advanced abdominal pregnancy with surviving newborn. The placenta was inserted at the base and side walls of fossa Douglas. Fetal, umbilical and retroplacental arterial Doppler ultrasound examinations revealed normal velocity waveforms. These findings indicated that the trophoblast invasion to the retroplacental arteries also occurs when the placenta has an extra-uterine insertion, and this can result in a normal placental blood supply and function.
在一例晚期腹腔妊娠且新生儿存活的病例中，记录到母体血清中未结合雌三醇和人胎盘催乳素激素水平正常，以及无应激试验胎心监护呈正常反应型。胎盘附着于Douglas窝底部和侧壁。胎儿、脐动脉和胎盘后动脉的多普勒超声检查显示速度波形正常。这些发现表明，当胎盘在子宫外附着时，滋养层也会侵入胎盘后动脉，这可导致正常的胎盘血液供应和功能。
