Background The metabolic enhancement resulted from hyperglycemia in gestational diabetes leads to macrosomia, which can affect the placenta. In gestational diabetes mellitus (GDM) pregnant women, the thickness of placenta and cord diameter can change at ages prior to treatment initiation. Therefore, this study was conducted to examine the thickness of placenta an...

background: placenta previa (pp) is an obstetric complication that can affect maternal and fetal morbidity and mortality. its prevalence is rising due to cesarean sections. there is no quantitative data of placenta in pp. in this study, quantitative parameters of placenta in cases with pp in comparison with normally implanted controls were investigated. methods: in this quasi experimental study...

PURPOSE The aim of this study is to evaluate the efficacy of an ultrasonographic measurement of placental thickness and the correlation of a thick placenta with adverse perinatal outcome. METHODS Placental thickness was measured in single gravidas, 16 to 40 weeks of gestation, between 2005 and 2009. Placentas were considered to be thick if their measured thickness were above the 95th percenti...

abstract background: previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function. objective: the present study focused on the effect of maternal morphine consumption on development of placenta and blood corticosteron concentration in addictive pregnant mothers. materials and methods: 24 female rats, 170-200g weigh...

BACKGROUND Pregnancy induced hypertension results from defective trophoblast invasion and increased umbilical artery resistance which in turn results in decreased blood supply to the placenta and hence to the foetus. This arterial resistance varies in different cases of PIH thus causing variable effects on placenta and foetus. The objective of this study was to study the morpho-metric changes i...

BACKGROUND: Placenta is a discoid, chorio-deciduate organ which connects the foetus with the uterine wall of mother. Maternal hypertension during pregnancy represents changes in morphological parameters of placenta. MATERIAL AND METHODS: 100 cases of hypertensive disorder of pregnancy and 100 placenta from normal cases between gestational age 28 to 42 weeks at SSG Hospital attached to Medical C...

Background: Previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function .The most attention of research focuses on the embryo, whereas it was not attended to the placenta as an important organ which is affected by opioides. The present study focused on the effect of maternal morphine consumption on development of ...

STUDY QUESTION Is endometrial thickness measured prior to embryo transfer associated with placenta praevia? SUMMARY ANSWER Following IVF, the risk of placenta praevia is increased 4-fold in women with an endometrial thickness of >12 mm compared with women with an endometrial thickness of <9 mm. WHAT IS KNOWN ALREADY Placenta praevia is a serious complication of pregnancy with adverse matern...

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...
