Changes in the Serum Levels of Human Chorionic Gonadotropin and the Pulsatility Index of Uterine Arteries during Conservative Management of Retained Adherent Placenta

Abstract

The changes in serum hCG observed in this study indicated the spontaneous degeneration of the placenta. Such changes might be similar to those reported to occur during treatment with methotrexate. In contrast, the PI of the uterine arteries did not reflect degeneration of the placenta.
