Stillbirth due to placental hypoperfusion after salpingo-oophorectomy for an ovarian cyst.

BACKGROUND: Gravid oophorectomy past mid-pregnancy may be necessary, but the alterations of blood flow to supply the placenta may present risks to the mother and fetus. CASE: A salpingo-oophorectomy for a mucinous cystadenoma resulted in a postoperative hemorrhage of 2 L and fetal death. The placenta demonstrated a unique lesion that was consistent with global hypoperfusion of the placenta. CONCLUSION: The postoperative hemorrhage occurred despite good immediate operative hemostasis. Blood flow was shunted from the uteroplacental circulation due to the large utero-ovarian collateral circulation.
