Association of first Birth Cesarean Delivery and Placental Abruption or Previa at Second Birth

ABSTRACT Objective To evaluate the strength of association of cesarean delivery for first birth with placenta previa and placental abruption in second pregnancy. Design Retrospective cohort study. Setting Hospital based (Birth register)2004-2008. A total of 1638 pregnancies were available for the final analysis after excluding missing information. Methods Multiple logistic regressions were used to describe the relationship between cesarean section for first birth with placenta previa and placental abruption in second birth singletons. Main outcome measures Placenta previa and placental abruption Results Placenta previa was present in 10 per 1000 second-birth singletons whose first births delivered by cesarean section and 9 per 1000 second-birth singletons whose first births delivered vaginally. The corresponding figures for placental abruption were 5 per 1000 in the previous cesarean delivery group and 5 per 1000 in the previous vaginal delivery group. The adjusted odds ratio (95% confidence intervals) of previous cesarean section for placenta previa in following second pregnancies was 1.10 (0.39 to 3.10) after adjusting for confounders including maternal age and interval between births. The corresponding figure for placental abruption was 1.0 (0.24 to 4.19). Conclusion Cesarean section for first birth is associated with 10% increased risk of placenta previa and no risk of placental abruption in second pregnancy with a singleton.

Background: This systematic review and meta-analysis summarizes the evidence for the association between endometriosis and adverse pregnancy outcome, including gestational hypertension, pre-eclampsia, low birth weight, and small for gestational age, preterm birth, placenta previa, placental abruption, cesarean section, stillbirth, postpartum hemorrhage, spontaneous hemoperitoneum in pregnancy, and spontaneous bowel perforation in pregnancy. Methods: We performed the literature review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), by searches in PubMed and EMBASE, until 1 November 2020 (PROSPERO ID CRD42020213999). We included peer-reviewed observational cohort studies and case-control studies and scored them according to the Newcastle–Ottawa Scale, to assess the risk of bias and confounding. Results: 39 studies were included. Women with endometriosis had an increased risk of gestational hypertension, pre-eclampsia, preterm birth, placenta previa, placental abruption, cesarean section, and stillbirth, compared to women without endometriosis. These results remained unchanged in sub-analyses, including studies on spontaneous pregnancies only. Spontaneous hemoperitoneum in pregnancy and bowel perforation seemed to be associated with endometriosis; however, the studies were few and did not meet the inclusion criteria. Conclusions: The literature shows that endometriosis is associated with an increased risk of gestational hypertension, pre-eclampsia, preterm birth, placenta previa, placental abruption, cesarean section, and stillbirth.

Placenta previa is a life threatening pregnancy complication where placenta partially or completely covers the internal cervical os causing serious adverse consequence for both mother and baby. History of cesarean delivery is an important risk factor for placenta previa. Which have a increased chance of cesarean hysterectomy and bladder injury because of an associated accrete syndrome. The objective of this study is to analyze the outcome of placenta previa with history of cesarean section. This is a prospective study done in Faridpur Medical College Hospital, Bangladesh from 01.01.2013 up to 31.12.14. Total 18 (study group) patients had undergone cesarean delivery with placenta previa and history of previous cesarean section. Among 18 patients maternal age range was 25- 40, parity 1-4, emergency hysterectomy was done in 11, average blood transfusion 2-8 and other morbidity like urinary bladder injury was 4. So we decided to conduct the study to evaluate the frequency of the placenta previa and morbidity related to number of previous cesarean deliveries.Faridpur Med. Coll. J. Jul 2015;10(2): 52-54

Introduction The incidence of cesarean section has been rising in the past 50 years. With the increased number of cesarean sections, the number of pregnancies with the previous cesarean section rises as well. The aim of this study was to establish the influence of the previous cesarean section on the development of placental complications: placenta previa, placental abruption and placenta accreta, as well as to determine the influence of the number of previous cesarean sections on the complication development. Material and methods The research was conducted at the Clinic of Gynecology and Obstetrics in Nis covering 10-year-period (from 1995. to 2005.) with 32358 deliveries, 1280 deliveries after a previous cesarean section, 131 cases of placenta previa and 118 cases of placental abruption. The experimental groups was presented by the cases of placenta previa or placental abruption with prior cesarean section in obstetrics history, opposite to the control group having the same conditions but without a cesarean section in medical history. RESULTS The incidence of placenta previa in the control group was 0.33%, opposite to the 1.86% incidence after one cesarean section (p<0.001), 5.49% after two cesarean sections and as high as 14.28% after three cesarean sections in obstetric history. Placental abruption was recorded as placental complication in 0.33% pregnancies in the control group, while its incidence was 1.02% after one cesarean section (p<0.001) and 2.02% in the group with two previous cesarean sections. The difference in the incidence of intrapartal hysterectomy between the group with prior cesarean section (0.86%) and without it (0.006%) shows a high statistical significance (p<0.001). CONCLUSION The previous cesarean section is an important risk factor for the development of placental complications.
