Placenta Accreta Spectrum Disorder: Uterine Dehiscence, Not Placental Invasion.
Obstetrics and Gynecology, 2020For decades, placenta accreta spectrum disorder has been classified, staged, and described as a disorder of placental invasion. In this commentary, we argue that placenta accreta spectrum exists as a disorder of defective decidua and uterine scar ...

Laterally-positioned placenta in placenta previa
The Journal of Maternal-Fetal & Neonatal Medicine, 2019Objectives: To clarify perinatal outcomes of patients with placenta previa (PP) with the placenta mainly positioned in the lateral uterine wall (lateral PP), thereby clinically characterizing this condition.Study design: The retrospective cohort study was performed involving patients with lateral PP between January 2006 and December 2016. The placental

Radiology, 1978
The author reviewed 249 arterial placentograms obtained between 1964 and 1974. In some cases a placenta, which at first lies low and encroaches on the incipient lower uterine segment, will move upwards towards the fundus and come to rest wholly in the upper uterine segment as gestation progresses. The mechanism of this movement and the possible reasons

Pediatric Clinics of North America, 1972
A number of drugs, if administered during pregnancy, have the potential of increasing or decreasing the blood supply to the developing fetus via a variety of mechanisms. Two aspects of placental pharmacology are considered here: the capacity of the placenta to catalyze the biotransformation of xenobiotic (drug) substrates, and the effects of drugs on ...

Placenta Previa and Placenta Accreta
2011The term placenta previa refers to a placenta that is abnormally located in the lower part of the uterus, often covering the cervix. The words are derived from the Latin pre, meaning before, and via, which comes from the same derivation as “viaduct” and “avenue,” meaning passageway.

The Placenta Accreta Spectrum: Epidemiology and Risk Factors
Clinical obstetrics and gynecology, 2018The placenta accreta spectrum has become an important contributor to severe maternal morbidity. The true incidence is difficult to ascertain, but likely falls near 1/1000 deliveries. This number seems to have increased along with the rate of risk factors.

Abruptio Placenta and Placenta Previa
2017The major causes of antepartum hemorrhage include placenta previa, placental abruption, uterine rupture, and vasa previa. Placenta previa occurs when the placenta implants over the cervical os. This implantation may be marginal, partial, or total in its covering of the os. The incidence of placenta previa is 4.0 per 1000 pregnancies.

Most placentas are normal, as are most babies. Therefore, an examination of all placentas may not be warranted, although this has been advocated repeatedly. Practical guidelines, including indications for the examination, have been published by the College of American Pathologists (Langston et al. 1997).
