Abruptio Placenta and Placenta Previa

2017
The 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.

THE EXPECTANT MANAGEMENT OF PLACENTA PREVIA

Obstetrical & Gynecological Survey, 1948
Abstract One hundred five cases of placenta previa with one maternal death (0.95 per cent) and twenty-nine fetal deaths (28 per cent) are reviewed. The adequate replacement of blood loss, and caution in the use of vaginal manipulations, with delivery either by cesarean section, or induction of labor by rupture of the membranes, dependent upon the ...

Abnormal Placentation

Obstetrics & Gynecology, 2015
Placental disorders such as placenta previa, placenta accreta, and vasa previa are all associated with vaginal bleeding in the second half of pregnancy. They are also important causes of serious fetal and maternal morbidity and even mortality. Moreover, the rates of previa and accreta are increasing, probably as a result of increasing rates of cesarean

Etiology of hemorrhage in placenta previa

American Journal of Obstetrics and Gynecology, 1951
Abstract The generally accepted theory that hemorrhage in placenta previa results purely from mechanical separation of the placenta following the development and formation of the lower uterine segment, effacement or dilation of the cervix, or following intravaginal manipulation must be disregarded.
