Cesarean scar defects and placental abnormalities; a 3 year survey study

Abstract

The placenta is an essential organ for embryonic and fetal development, ensuring nutrient uptake, gas exchange (via the mother's blood supply), waste elimination, thermo-regulation, immunological and hormonal factors, etc. The most common placental abnormalities are represented by placenta previa, and a morbidly adherent placenta (in the form of accreta, increta, and percreta placenta). This study was performed on a sample of 99 patients diagnosed with abnormalities of placentation who underwent cesarian delivery during a period of 3 years in Bucur Maternity Hospital. Seven patients were diagnosed with morbidly adherent placenta (5 accreta and 2 percreta subtypes), the others having placenta previa (65 with lateral disposition, 18 marginal, and 9 central insertion). All patients had been diagnosed by ultrasound (which was also used for general monitoring), being confirmed during operation and histopathologically. Complications required 4 emergency peripartum hysterectomies, with no maternal mortality but with fetal death in one case. The research literature shows that about half of women with placenta previa have several episodes of bleeding, being the leading cause of antepartum hemorrhage. For some women with placenta previa/accrete, hemorrhaging is severe and requires hysterectomy as a necessary step to control the life-threatening situation. Thus, such patients should be carefully monitored to avoid as much as possible the medical, social, and psychological implications of this critical therapeutic procedure.
