Association Between First-Trimester Bleeding and Retained Placenta Requiring Dilatation and Curettage.

J Obstet Gynaecol Can 2021 Apr 25;43(4):463-468. Epub 2020 Aug 25.

Department of Obstetrics and Gynecology, Jewish General Hospital, McGill University, Montréal, QC; Centre for Clinical Epidemiology and Community Studies, Jewish General Hospital, Montréal, QC. Electronic address:

Objective: Early subchorionic hemorrhage may lead to a disruption in the placental-uterine matrix, which may result in an adherence of the placenta to the endometrium. We evaluated the effect of a first-trimester bleed on the need for a post-vaginal delivery dilatation and curettage (D&C) for removal of retained placenta.

Large Subchorionic Cyst Located at Umbilical Cord Insertion with Vascular Displacing and Intracystic Hemorrhage/Hematoma: A Case Report.

Fetal Pediatr Pathol 2020 Oct 24:1-7. Epub 2020 Oct 24.

Unit of Obstetrics & Gynecology, Azienda USL - IRCCS di Reggio Emilia, Reggio Emilia, Italy.

Background: Large subchorionic cysts usually arise close to the placental cord insertion site (PCIS) inducing traction on the umbilical cord, impairing blood flow and favoring fetal growth restriction (FGR). Intracystic hemorrhage/hematoma is likely due to the prothrombotic properties of X cells secretion (extravillous trophoblast), which line the cyst wall. We describe a large subchorionic cyst located exactly at the PCIS, displacing the umbilical cord vessel branches running along the cyst surface. Read More

[Effect of rivanol-induced abortion on placental histology: pitfalls in pathological interpretations].

Zhonghua Bing Li Xue Za Zhi 2020 Aug;49(8):782-787

Department of Pathology, Obstetrics and Gynecology Hospital of Fudan University, Shanghai 200011, China.

Placental pathology reflects the health condition of both mother and fetus during pregnancy, providing information about pathogenesis especially in adverse pregnancies, and may provide guidance on subsequent pregnancies. Description on the placental changes after long-term use of rivanol is lacking, and this evaluated the placental changes, with emphasis on the differential diagnosis from other primary placental lesions. A total of 85 placentas from rivanol induced abortion submitted to the Department of Pathology, Obstetrics and Gynecology Hospital of Fudan University from Januaury 2017 to October 2019 were reviewed; and 81 gestational-age-matched cases of spontaneous abortion or preterm delivery during the same period were also included as the control group.
