PLACENTAL ABRUPTION. Placental abruption is characterized by spontaneous behind or within the placenta. It may result from extravasation of maternal or fetal blood. Hematomas of fetal origin are secondary to rupture of a chorionic vessel before or during delivery, and are localized under the amniotic layer (subamniotic) covering the fetal plate.Feb 18, 2019 Definition general. Hematomas between the basal plate and uterus form due to acute or chronic hemorrhage; if significant ( 50), there is an increased risk of fetal death. Smaller hematomas pose a risk for vaginal bleeding, oligohydramnios and premature delivery. Diagnosis of abruption is clinical; findings in the placenta may not be sufficient. retroplacental hemorrhage pathology

PLACENTAL PATHOLOGY Michael K Fritsch MD, PhD. NORMAL HISTOLOGY REVIEW: 1) Membranes: The amnion lines the amniotic sac containing the fetus. The amnion consists of a single layer of cuboidal epithelium, its basement membrane, and a collagen layer. The fibrous chorion lies deep to the amnion and consists of a sparsely cellular collagen layer.

hemorrhage including retroplacental hematoma (Retropl. H. ) during pregnancy and delivery is a large part [2. Retropl. H. Intercurrent pathology like HBP and Diabetes are associated with the onset of retroplacental hematoma (Table 6). Discussion The incidence of Retropl. H. This large retroplacental blood clot is the result of a condition known as abruptio placenta. Such abnormal retroplacental hemorrhage prior to delivery can lead to sudden onset of pain in the mother and loss of fetalmaternal circulation that could cause fetal demise.retroplacental hemorrhage pathology Diagnosis of placental abruption. The most common indication leading to a clinical diagnosis of abruption (Table 2) was evidence of retroplacental clot(s) or bleeding (77. 1), followed by vaginal bleeding with uterine hypertonicity (27. 8) and by vaginal bleeding with nonreassuring fetal status (16. 1).

Pathology. This type of haemorrhage occurs behind the placenta. The haematoma therefore separates the placenta from the uterine wall. The source of bleeding is probably from spiral arteries. retroplacental hemorrhage pathology How can the answer be improved? The other locations were cervical in 63 patients (34), fundal in 30 (16), and posterior in 19 (10). The hematoma was subchorionic in 91 pregnancies (57) and retroplacental in 68 of 159 pregnancies (43). It was not possible to localize the hematoma in 28 cases because of early gestational age (less than 7 to evaluate evidence of placental hemorrhage (PH) obtained through maternal interviews, patient charts, and placental pathology examinations as potential indicators of a bleeding pathway to preterm delivery (PTD). pain, increased uterine tone, fetal distress); or (2) retroplacental hematoma visualized on a prenatal ultrasound scan
