Background: Uncertain fetal head engagement represents 4% of obstetrical situations associated with an increased risk of postpartum hemorrhage, notably in cases of cesarean delivery and increased neonatal impairment owing to failed vaginal instrumental delivery. In this obstetrical condition, cesarean delivery is recommended, but vaginal delivery is possible in two-thirds of the cases. During the second stage of labor, the descent of the fetal head can be assessed by sonography, particularly by measuring the angle of progression.

Background: Persistent occiput posterior and occiput transverse positions are the most common malpositions of the fetal head during labor and are associated with prolonged second stage of labor, cesarean deliveries, instrumental deliveries, severe perineal tears, postpartum hemorrhage, and chorioamnionitis. Manual rotation is one of several strategies described to deal with these malpositions.

Objective: This study aimed to determine if the trial of prophylactic manual rotation at the early second stage of labor is associated with a decrease in operative deliveries (instrumental and/or cesarean deliveries).

The aim of this study was to identify specific unusual prenatal ultrasound (US) patterns of the adrenal gland and to propose a systematic approach for diagnosis. Six fetuses with unusual aspects of one or both adrenal glands, detected during routine prenatal US screening, were evaluated. Prenatal and postnatal management are described.

Article Synopsis
  • The study aimed to determine if a history of cesarean delivery due to arrest of descent affects the success rate of vaginal births after cesarean (VBAC).
  • Researchers conducted a multicenter study involving 480 women who had previously undergone cesarean deliveries, comparing those with a history of arrest of descent to those with other reasons for cesarean.
  • Results showed no significant differences in the success rates of VBAC between both groups, suggesting that it's safe to attempt labor after a cesarean due to fetal head engagement issues.

Placental chorioangioma is a limited non trophoblastic vascular tumour that may causes fetal complications as well as post-natal ones. We reported in here the first case of an in utero embolization of chorioangioma diagnosed at 22 W G with a post-natal diagnosis of neonatal multifocal hemangioma with a good outcome. The chorioangioma was embolized using GLUBRAN 2 ® (cyanolacrylate) a biologic surgical glue at 26 W G.

Postpartum haemorrhage (PPH) is defined as blood loss ≥500mL after delivery and severe PPH as blood loss ≥1000mL, regardless of the route of delivery (professional consensus). The preventive administration of uterotonic agents just after delivery is effective in reducing the incidence of PPH and its systematic use is recommended, regardless of the route of delivery (Grade A). Oxytocin is the first-line prophylactic drug, regardless of the route of delivery (Grade A); a slowly dose of 5 or 10 IU can be administered (Grade A) either IV or IM (professional consensus).

Article Synopsis
  • The study aimed to find events linked to emergency caesarean sections in women with antepartum bleeding and placenta praevia, and to create a predictive scoring system for such emergencies after a first bleeding episode.
  • The research involved 250 women and analyzed risk factors to develop a score from data collected on 163 patients, later validated with a second group of 87 patients.
  • Key findings identified major praevia, multiple bleeding episodes, and early first bleeding as significant risk factors, leading to a scoring system that predicted emergency caesareans with varying sensitivity and specificity based on the cohort.

Objective: To study cervix elastography measurement and its relation with pregnancy outcome.

Design: A two year prospective longitudinal study evaluated cervical elasticity by HI-RTE (Hitachi real-time tissue elastography) imaging during three trimesters of pregnancy. The main outcome measure was elastography index the cervical elastogram color-coded.

Article Synopsis
  • The study investigates the role of soluble major histocompatibility complex class I related chain (sMIC) in immune disorders linked to vascular pregnancy diseases (VPD).
  • It was found that sMIC levels were significantly higher in women with VPD (32%) compared to healthy pregnancies (1.6%), particularly in cases of intrauterine fetal death (44%) and vascular intrauterine growth restriction (39%).
  • The presence of sMIC is associated with changes in immune cell function, potentially impairing NK cell activity and impacting important processes like vascular remodeling during pregnancy.

Objective: To evaluate short and medium term outcomes of children born of monochorionic pregnancies complicated by twin-twin transfusion syndrome treated by fetoscopic laser surgery.

Methods: This was a retrospective observational study performed between May 2007 and 2012. Neonatal data was from 45 patients under 5 years of age.

The primary cause of uterine scars is a previous cesarean. In women with a previous cesarean, the risks of maternal complications are rare and similar after a trial of labor after cesarean (TOLAC) and after an elective repeat cesarean delivery (ERCD), but the risk of uterine rupture is higher with TOLAC (level of evidence [LE]2). Maternal morbidity in women with previous cesareans is higher when TOLAC fails than when it leads to successful vaginal delivery (LE2).

The duration of pregnancy varies between 40(+0) and 41(+3) weeks. Conventionally, and essentially arbitrarily, a pregnancy is considered to be "prolonged" after 41(+0) weeks, but the infant is not considered "post-term" until 42(+0) weeks (Professional consensus). A term birth thus occurs during the period from 37(+0) to 41(+6) weeks.
