Placental Sonomorphologic Appearance and Fetomaternal Outcome in Fontan Circulation [PDF]
Journal of Clinical MedicineObjectives: Pregnancies in women with Fontan circulation are on the rise, and they are known to imply high maternal and fetal complication rates. The altered hemodynamic profile of univentricular circulation affects placental development and function ...

Observations on the fetal aspects of placental circulation
American Journal of Obstetrics and Gynecology, 1951Abstract 1. 1. The fetal vascular ramifications of the human placenta have been studied with a variety of injection techniques. Vinyl acetate injected placentas have been corroded. India ink-injected material has been cleared with a modified Spalteholtz procedure. 2. 2.

Circulating Angiogenic Factors and Placental Abruption
Obstetrics & Gynecology, 2006Abnormalities in circulating angiogenic factors have been reported in diseases of abnormal placentation, such as preeclampsia and intrauterine growth restriction. Our objective was to determine whether circulating angiogenic factors are altered in another placental vascular disease, abruptio placentae.In a nested case-control study of nulliparous ...

Studies in placental circulation
American Journal of Obstetrics and Gynecology, 1970Planimetric estimations of placental surface have emphasized total villus area. This, however, is not always equivalent to vascular area upon which fetomaternal exchange ultimately depends. Using microphotographs of fresh-placental tissue, a study was undertaken to determine the relationship between villus and vascular areas in normal and abnormal ...

Circulating and utero-placental adaptations to chronic placental ischemia in the rat
Placenta, 2012While utero-placental insufficiency is associated with adverse outcomes for both mother and fetus, many of the maternal-fetal adaptations during pregnancy in models of fetal compromise remain unclear. The purpose of this study was to determine if chronically reduced uterine perfusion pressure (RUPP) during days 14-19 of gestation alters feto-placental ...

Disorders of Placental Circulation and the Fetal Brain
Clinics in Perinatology, 2009Disorders of the placental circulation, including the release of deleterious mediators to the fetus, are important risk factors for central nervous system complications. These disorders result in discrete patterns of placental injury detectable by a thorough placental pathologic examination.

Placental Vasculature and Circulation in Primates
1988When the fertilized primate ovum, whether of human, monkey, baboon, or mangabey, comes to rest on the lining epithelium of the uterus, the trophoblast of its wall promptly begins to invade the endometrium over an ever widening base (Heuser and Streeter, 1941; Enders, 1976; Houston, 1969, 1975; Enders et al., 1983).

The anatomy and histology of placental circulation
American Journal of Obstetrics and Gynecology, 1934Abstract The greater part of our present-day knowledge of the placenta has been derived from investigation of the growth, disposition, and changes in its epithelium, as befits a glandular organ. The chemistry and biologic nature of the gland have also been investigated; likewise the pathology.
