Background: There is limited information on neonatal outcomes in complicated pregnancies with abnormal placentation. The aim of this study was to assess the neonatal outcomes of abnormal placentation.Methods: In this case-control study, known cases of abnormal placentation between the years 2010 and 2017 were extracted. The case group consisted of pregnant women with abnormal placentation (172 cases), while controls were selected from repeated cesarean section cases with normal placentation (341 people).Results: In the case group, 145 cases (84.3%) had placenta accreta, 12 cases (7.07%) had placenta increta and five cases (8.7%) had placenta percreta. Characteristics significantly more common in the case group included lower mean gestational age and average neonatal weight (p < .001), low birth weight (LBW) and small for gestational age (SGA) (p < .001), admission to the NICU (p < .001), higher average number of hospitalization days in the NICU (p < .05), lower average 5-minute Apgar scores (p < .001), neonatal seizure (p = .004), cranial hemorrhage (p = .037), anemia (p = .002) and thrombocytosis (p = .029). The occurrence of abnormal placentation was associated with some underlying maternal characteristics such as high maternal age (p = .34), lower maternal weight (p = .044), multiparity (p = .11), history of previous abortion (p = .036), and history of cesarean (p = .001). The prevalence of placenta previa was significantly higher in the case group (p < .001).Conclusion: The presence of placenta previa has a close relationship with abnormal placentation and is considered to be a potential risk factor for LBW, SGA, lower 5 minutes Apgar scores, first-day seizure, cranial hemorrhage, the necessity for NICU admission and occurrence of anemia and thrombocytosis in neonates.
Introduction Abnormally invasive placenta involves abnormal adherence of the placenta to the myometrium and is associated with severe pregnancy complications such as blood transfusion and hysterectomy. Knowledge of outcomes has been limited by small sample sizes and a focus on maternal rather than neonatal outcomes. This study uses population-level data collected over 10 years to investigate maternal and neonatal outcomes and trends in incidence of abnormally invasive placenta (also known as pla...

AbstractObjective: This study is aimed to identify the risk factors for the development of placenta accreta (PA) and characterize its effect on maternal and perinatal outcomes.Study design: This population-based retrospective cohort study included all deliveries at our medical center during the study period. Those with placenta accreta (n = 551) comprised the study group, while the rest of the deliveries (n = 239 089) served as a comparison group.Results: The prevalence of placenta accerta is 0....

Objective: Placenta accreta is an increasingly prevalent and potentially dangerous complication of pregnancy. Although most studies on the subject have addressed the risk factors for the development of this condition, evidence on maternal and neonatal outcomes for these pregnancies is scarce. The objective of the present study is to compile current evidence with regard to risk factors as well as adverse outcomes associated with placenta accreta. Methods: We conducted a complete literature review...

Objective We sought to evaluate risk factors and perinatal outcomes of pregnancies complicated with placenta accreta and to study perinatal outcomes in subsequent pregnancies. Study Design A retrospective study comparing all singleton cesarean deliveries (CD) of women with and without placenta accreta was conducted. In addition, a retrospective comparison of all subsequent singleton CD of women with a previous placenta accreta, with CD of women with no such history, was performed during the year...

Placenta accreta is a severe pregnancy complication and is currently the most common indication for peripartum hysterectomy. It is becoming an increasingly common complication mainly due to the increasing rate of cesarean delivery. Main risk factor for placenta accreta is a previous cesarean delivery particularly when accompanied with a coexisting placenta previa. Antenatal diagnosis seems to be a key factor in optimizing maternal outcome. Diagnosis can be achieved by ultrasound in the majority ...

Objective: The purpose of this study was to compare the risk of adverse neonatal outcomes between women with placenta accreta and placenta increta or percreta. Methods: This was a single institution retrospective cohort study of women with abnormal placentation (placenta accreta, increta, and percreta) who delivered from 1982–2002. Cases were divided into superficial invasion (placenta accreta) and deep invasion (placenta increta or percreta), and compared. The primary outcomes studied were gest...

Objective To estimate the incidence and describe the risk factors, management and outcomes of placenta accreta/increta/percreta. Methods A national population-based case-control study was undertaken using the UK Obstetric Surveillance System between May 2010-April 2011. Participants comprised 134 women with placenta accreta/increta/percreta and 258 controls. Results The estimated incidence of placenta accreta/increta/percreta was 1.7 per 10,000 maternities (95%CI 1.4-2.0). Older women had raised...

Objective To assess the role of three-dimensional (3D) power Doppler in the antenatal diagnosis of placenta accreta and compare its diagnostic performance with gray-scale and color Doppler ultrasonography. Methods One hundred and seventy pregnant women with persistent placenta previa totalis (after 28 weeks’ gestation) were prospectively enrolled into this study. Gray-scale transabdominal ultrasound examination was performed to detect loss of the subendometrial echolucent zone and other abnormal...

OBJECTIVE To assess differences in the perioperative complication rate between patients with placenta accreta spectrum (PAS) with and without complicating factors. METHODS This retrospective cohort study included subjects who underwent cesarean hysterectomy with histology-proven PAS between 23 0/7 and 42 0/7 weeks gestational age (GA) from 1 July 2008 to 11 April 2017. Perioperative outcomes were compared between those with uncomplicated PAS and "complicated PAS," defined as PAS subjects who exp...

Background Cartilage-hair hypoplasia (CHH) is a rare skeletal dysplasia characterized by disproportionate short stature, immunodeficiency, anemia and risk of malignancies. All these features can affect pregnancy and predispose to maternal and fetal complications. This study aimed to evaluate obstetric history and maternal and fetal outcomes in women with CHH. Methods Among 47 Finnish women with CHH, we identified 14 women with ICD codes related to pregnancies, childbirth and puerperium in the Na...
