Women with placenta previa are at increased risks for complications related to obstetrical hemorrhage and the need for emergent delivery. Some will remain asymptomatic without preterm labor or vaginal bleeding, and thus the clinician must decide when to schedule cesarean delivery in a "stable" patient. Decision-making for the optimal timing of delivery across the late preterm and early-term per...

Background and aim: Horseshoe placenta is a variant of ring-shaped placenta. Ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. This report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...

The retained placenta is a significant cause of maternal mortality and morbidity throughout the developing world. It complicates 2% of all deliveries and has a case mortality rate of nearly 10% in rural areas. Ultrasound studies have provided fresh insights into the mechanism of the third stage of labour and the aetiology of the retained placenta. Following delivery of the baby, the retro-place...

Reactive oxygen species are unavoidable products of metabolism and in excess they can be dangerous for tissues and cells. Superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), among others, protect tissues and cells against reactive oxygen species. The aim of the study was the description of SOD and GSH-Px from bovine placenta by use of spectrophotometric and electrophoretic analysis ...

Placenta previa accreta, the combination of placenta previa and placenta acrreta, can cause life-threatening massive post-partum hemorrhage (PPH) and may require emergent hysterectomy. Intraoperative transcatheter arterial embolization (TAE) performed after fetal delivery and before placenta expulsion can significantly reduce blood loss and preserve the uterus. However, TAE may fail under the s...

OBJECTIVES The purpose of this study was to evaluate the association between first-trimester sonographic findings and morbidly adherent placenta at delivery. METHODS We conducted a retrospective review of all first-trimester sonographic examinations from pregnancies that underwent third-trimester sonography for placenta previa or low-lying placenta between September 1997 and October 2011. Onl...

BACKGROUND Placenta previa, a major cause of obstetric hemorrhage, is potentially life-threatening to the mother and frequently results in high perinatal morbidity and mortality. METHODOLOGY This is a retrospective study of all cases of placenta previa managed at the University of Ilorin Teaching Hospital over a 5-year from January 2011 to December 2015. A pro forma template was used to harve...

Objective: To assess the value of adding three-dimensional (3D) power Doppler (as a diagnostic technique) to grayscale in the prenatal diagnosis of placenta accreta. Material and Methods: One hundred pregnant women with persistent placenta previatotalis (after 28 weeks' gestation) were prospectively enrolled into this study. Gray-scale transabdominal ultrasound was performed to detect loss of t...

OBJECTIVE To identify risk factors for preterm delivery in women with placenta praevia and antepartum haemorrhage. DESIGN Retrospective study. SETTING Regional obstetric unit, Hong Kong. SUBJECTS AND METHODS Women delivered at Princess Margaret Hospital between 1 January 1990 and 31 December 1997. Possible risk factors for preterm delivery among women with placenta praevia and antepartum ...
