Background: The prevalence of both placenta previa and cesarean are on the rise. Multiple adverse outcomes are critically increased when placenta previa is subsequent to prior cesarean. The purpose of the present study is to develop a pre-surgical method for predicting adverse outcomes in pregnancy complicated with both placenta previa and prior cesarean.

Methods: Clinical data was obtained from the medical history system at the First Affiliated Hospital of Sun Yat-sen University from February 2003 to December 2016. All cases with a final diagnosis of "placenta previa/low lying placenta (ICD:O44.001-105)" and "scarred uterus complicated with pregnancy (ICD: O34.200-202)" were collected and reviewed. Hysterectomy was taken as the primary outcome; and blood loss was taken as the secondary outcome.

Results: Of 219 pregnant women in the final analysis, 25 received a hysterectomy following delivery, and 48 had blood loss exceeding 1000 ml. Pre-surgical risk factors for hysterectomy are ultrasonic signs of vascular lacunae, central placenta previa, and loss of normal hypoechoic retroplacental zone. A pre-surgical predictive equation referred to as "Hysterectomy Index in Placenta Previa with Prior cesarean (HIPs)" was generated and each risk factor was weighted to create an 8-point scale. This index yielded an area under the curve of 0.972 for the prediction of hysterectomy.

Conclusions: Application of the HIPs score may provide an effective pre-surgical prediction of cesarean hysterectomy in pregnant women complicated with both placenta previa and prior cesarean.

Risk Factors for Antepartum Haemorrhage in Women With Placenta Praevia.

Aust N Z J Obstet Gynaecol

January 2025

Obstetrics and Gynaecology, Mater Mothers Hospital, Brisbane, Queensland, Australia.

Background: Placenta praevia (PP) is a significant obstetric complication associated with antepartum haemorrhage (APH) and adverse maternal and fetal outcomes. Identifying risk factors for APH in women with PP is important for guiding management decisions.

Aims: This study aimed to identify risk factors associated with APH amongst women admitted to a single tertiary hospital with PP.

Introduction And Clinical Importance: Placenta previa (PP) is characterized by abnormal placental placement in the lower uterine segment, obstructing the cervical opening. Placenta previa totalis (PPT) occurs when the placenta completely covers the internal cervical os. This condition can lead to placenta accreta spectrum (PAS), where the placenta adheres abnormally to the uterine wall, complicating separation.

Background: Like other countries in sub-Saharan Africa, Madagascar has a high burden of maternal and neonatal mortality. However, as the proportion of foetal and placental abnormalities among the Malagasy population is unknown, strategies aimed at reducing maternal and neonatal mortality are challenging to define and implement.

Methods: We conducted a multi-year, cross-sectional study using secondary NGO data on obstetric ultrasound, including patient records of all pregnant women who received an obstetric ultrasound screening between July 1st, 2017, and September 30th, 2020, at 62 public-sector primary care facilities in urban and rural regions of Madagascar.

Prevalence and risk factors associated with birth asphyxia among neonates delivered in China: a systematic review and meta-analysis.

BMC Pediatr

December 2024

Department of Nursing, Shenzhen People's Hospital (The Second Clinical Medical College, Jinan University; The First Affiliated Hospital, Southern University of Science and Technology), Shenzhen, Guangdong, China.

Background: Birth asphyxia is a critical condition caused by an insufficient oxygen supply during delivery, and it poses a major threat to the health of newborns. The present meta-analysis aimed to estimate the prevalence of birth asphyxia among neonates and identify its risk factors in China.

Methods: PubMed, EMBASE, Scopus, Web of Science, the China Academic Journals (CNKI), the Chinese Biomedical Literature (CBM), the China Science and Technology Journal Database (VIP), and the WanFang database were searched for related publications.

This study aimed to evaluate our center's experience in diagnosing and managing placenta accreta spectrum (PAS) in a high-risk population, focusing on prenatal ultrasound features associated with PAS severity and maternal outcomes. We conducted a retrospective analysis of 102 high-risk patients with confirmed placenta previa who delivered at our center between 2018 and 2023. Patients underwent transabdominal and transvaginal ultrasound scans, assessing typical sonographic features.
