She had two previous antenatal coouvelaire at the PHC. Abruptions have occurred after seemingly minor maternal injuries. Subsequent organization of this concealed area of infarction may be identified as a white placental infarct at the time of delivery.
The renal lesion of toxemia and abruptio placentae studied by light and electron microscopy.

Anterior pituitary necrosis with delayed onset of the signs and symptoms of hypopituitarism originally was discussed by Sheehan in An emergency lower segment caesarean section was performed for non-progression of labour due to cephalopelvic disproportion with central placenta praevia with significant fetal distress. Other suggested mechanisms are vasospasm of the supplying arteries caused by humoral serotonin release or reflex uterorenal factors.
Other traumatic etiologies of abruption include separation of the placenta in a twin gestation after delivery of the first twin with subsequent decompression, attempted external cephalic version, and drainage of amniotic fluid associated with polyhydramnios in rare cases after amniocentesis for maturity studies.
If the placenta is posteriorly implanted, uterine tenderness itself may be absent, but the patient may experience lower back pain.
N Engl J Med In less severe cases, the area of uterine tenderness and spasm varies and may be absent or confined to a limited area that often corresponds to the placental location. The three major causes of perinatal death are fetal anoxia, exsanguination because, in rare cases, rupture of fetal placental vessels can occurand, especially, prematurity.
Except for mild cramping, some patients may remain asymptomatic. If vaginal delivery is expected, which in some cases, depending on maternal and fetal status, may be the preferred route, the obstetrician should attempt an amniotomy as soon as possible, because it may benefit labor and also allows the placement of internal monitoring if desired.
Interference with the diffusion of oxygen in the intervillous area from the maternal to the fetal side is to be expected in placental abruption.
Because heparin or fibrinolytic inhibitors may lead to more severe hemorrhage, they should not be used in patients with DIC. An assessment of the time and method of delivery. Perhaps the entire entity may be a progressive stress or accelerated degeneration of an already defective vasculature of the placental bed. This temporal increase in rates of abruption may reflect a true increase in risk, or may be the result of improved diagnosis of both abruption and its determinants.
Other maternal congenital thrombophilias have been found in patients with abruptio placentae, such as protein S and ciuvelaire C deficiencies, 70 along with antithrombin III deficiency. Placentae previa and abruptio placentae.
After a brief initial evaluation, a careful speculum examination should be performed to ensure that the bleeding is coming from the uterine cavity rather than the perineum, vagina, or cervix. Fortunately, this condition generally is reversible with proper management.
The concept of ischemic placental disease will be further discussed later in this chapter. Baudelocque, inexpanded couvelairee term to concealed accidental hemorrhage.
The coagulopathy must be corrected to ensure adequate hemostasis in the case of a cesarean delivery. Doppler blood flow changes and placental morphology in pregnancies with third trimester hemorrhage.
Digestive system Acute fatty liver of pregnancy Gestational diabetes Hepatitis E Hyperemesis gravidarum Intrahepatic cholestasis of pregnancy.
Partial placental detachment from the lower uterine cavity was noted. The aetiology and outcome of abruptio placentae. Activated protein C is effective for disseminated intravascular coagulation associated with placental abruption. Retroplacental blood may penetrate through the thickness ktero the uterine wall into the peritoneal cavity, a phenomenon known as Couvelaire uterus.
Placental bed biopsies in placental abruption. Histologic evidence of inflammation and risk of placental abruption. The presence or absence of any of the previously mentioned symptoms and the degree of severity are directly proportional to the magnitude of the placental separation. Despite numerous clinical and epidemiologic studies, the etiology of placental abruption is ve to be precisely determined, but it is thought to be a disease of the decidua and uterine blood vessels.
