[Abdominal pregnancy: hormon concentrations during the postpartal period with placenta remaining intra-abdominal (author's transl)].

It is reported of an abdominal pregnancy at term. The placenta was left in situ because of the high risk of intraabdominal bleedings. Thereby it was possible to measure hormon concentrations of the fetoplacental unit without the fetal compartment. Within 10 days after delivery we determined the plasma levels of estradiol-17 beta, estriol, progesterone, HCS, alpha1fetoprotein, and the excretion of the total estrogens in the urines. There was near the same decrease of hormon concentrations in the post partal time comparable with that of a normal pregnancy. Only the HCS concentrations didn't change in the first 9 days after delivery.
