The effect of the duration between the previous ceserian section and the current pregnancy on the incidence of placenta accreta spectrum: A Case Control Study

Abstract

Abstract Background Placenta accreta spectrum is a serious obstetric disorder that is characterized by deeply penetrating villi which are abnormally attached to the myometrium of the uterus. This prevents its complete dissociation during the third stage of labor that may cause severe bleeding, with its marked risk on the mother life. All recent studies confirm that the occurrence of placenta accreta increased dramatically in the recent years with the increasing number of caesarean sections. The number of previous caesarean deliveries accompanied by placenta previa markedly increase the risk for placenta accreta. There is a continued need to study risk factors of abnormally adherent placenta to improve the antenatal diagnosis . Objective The current study aims to evaluate the effect of the short duration between the perior caesarean delivery and the current pregnancy on the occurence of placenta accreta spectrum. Patients and Methods a case control study which was performed in the Maternity Hospital of Ain Shams University. It compare the duration between the perior caesarean section and the current pregnancy in the placenta accreta cases and the matched controls to determine if it increases the occurrences of placenta accreta or not. It include all pregnant ladies with placenta accreta spectrum diagnosed radiologically or surgically in the period of the beginning of June 2019 to the beginning of December 2019 with in the inclusion criteria, also the matched controls. Results there was no difference with a statistical significance between control group and patients group regarding inter pregnancy interval. Conclusion this study reveals that there was no effect of the short duration between the previous caesarean delivery and the current pregnancy on the occurence of placenta accreta spectrum.
