Placenta accreta is a severe complication of pregnancy normally diagnosed during the second trimester. Early detection could reduce risk hemorrhage abortion or miscarriage; however, guidelines on first-trimester diagnosis are lacking. We describe case placenta first trimester with its sonographic and histological features.

OBJECTIVES To identify the incidence of morbidly adherent placenta in the context of a rising caesarean delivery rate within a single institution in the past 15 years, and to determine the contribution of morbidly adherent placenta to the incidence of massive postpartum haemorrhage requiring hysterectomy. SETTING A regional obstetric unit in Hong Kong. PATIENTS Patients with a morbidly adhe...

A single placenta normally supports a single fetus. When the situation arises in which two fetuses have to share a single placenta, complications may sometimes develop. Identical twins that share a single placenta are called monochorionic twins (MC). ?Chorion? is the Latin root that refers to the placenta, while the word ?amnion? refers to the sac, or ?membranes? that surround each fetus. While...

We determined recent trends and recurrence rates of placenta praevia in 790,366 deliveries in NSW. From 2001 to 2009, the rate of placenta praevia increased by 26%, from 0. 69% to 0. 87% (trend P < 0.001). The placenta praevia recurrence rate in a second birth was 4.8%. Two-thirds of the increase in placenta praevia was accounted for by trends in known risk factors, and the unexplained portion ...

OBJECTIVE To test an objective ultrasound marker for diagnosing the presence and severity of abnormally invasive placenta. METHODS Women at risk of abnormally invasive placenta underwent a three-dimensional power Doppler ultrasound scan. The volumes were examined offline by a blinded observer. The largest area of confluent three-dimensional power Doppler signal (Area of Confluence [Acon], cm)...

Background: The dramatically increased in CS delivery will essentially increase incidence of cesarean scar defects (CSD) rate, which has deleterious effect on mother's health as ectopic pregnancy, placenta previa and morbidly adherent placenta, dehiscence, postmenstrual spotting, inter-menstrual bleeding, dysmenorrheal, dyspareunia, secondary infertility.

Objective(s): The placenta provides nutrients and oxygen to embryo and removes waste products from embryo’s blood. As far as we know, the effects of exposure to Wi-Fi (2.4 GHz) signals on placenta have not been evaluated. Hence, we examined the effect of prenatal exposure to Wi-Fi signals on anti-oxidant capacity, expressions of CDKNA1, and GADD45a as well as apoptosis...

Dangerous placenta previa refers to somebody has a history of cesarean section while this pregnancy was placenta previa with the placenta attached to the original scar. The placenta can be adhered to the surface of the uterus, invasion into myometrium or completely penetrate the muscle and tissues in these placenta previa patients. It happens in these persons like older maternal ages (over 35 y...

Placenta is a unique organ, without which the very phenomenon of human pregnancy impossible. Semiallogeneous nature, localization placenta, complex and heterogeneous cellular composition determines its multifaceted role in course physiological pregnancy, indicates importance studying this organ number reproductive pathologies. The purpose review was to analyze literature sources illustrating en...
