Benckiser's hemorrhage: about an uncommon case report
2022, International Journal of Surgery Case ReportsCitation Excerpt :Postnatal diagnosis can be made at delivery by macroscopic examination showing ruptured vessels running freely through the membranes and absence of insertion of the umbilical cord on the placenta, but on the membranes, more than two centimeters from the placental edge. As the occurrence of spontaneous rupture of membranes cannot be predicted, the Society of Obstetricians and Gynaecologists of Canada recommends that, if diagnosed early, antenatal corticosteroid therapy should be given at 28–32 weeks of amenorrhea, and that patients should be admitted to a level 3 maternity from 30 to 32 weeks of amenorrhea, but does not give an ideal term for a scheduled caesarean section [16]. Indeed, the term at which it should be performed is still debated and there are no studies with a sufficient level of evidence to answer this question.
Guideline No. 402: Diagnosis and Management of Placenta Previa
2020, Journal of Obstetrics and Gynaecology CanadaCitation Excerpt :All women with placenta previa or low-lying placenta have an increased risk of a morbidly adherent placenta (placenta accreta spectrum disorders), particularly those with a prior cesarean delivery.11,23 Further, all women with a placenta previa or low-lying placenta have an increased risk of vasa previa, particularly those with a marginal/velamentous cord insertion close to the cervical os or a succenturiate placental lobe.10,14,24 These conditions carry significant implications for maternal-fetal outcomes and need to be further assessed or ruled out.
Directive clinique n<sup>o</sup> 402: Placenta prævia: Diagnostic et prise en charge
2020, Journal of Obstetrics and Gynaecology CanadaUltrasound screening of umbilical cord abnormalities and delivery management
2018, PlacentaCitation Excerpt :A guideline recommends that hospitalisation at approximately 30–32 weeks and the administration of corticosteroids to promote foetal lung maturation be considered in affected patients [48]. Conversely, it has also been reported that in selected asymptomatic patients, outpatient management is also a possible option [48,49]. Nevertheless, precise outpatient investigations, including confirmation of the presence of uterine contractions and condition of the uterine cervix and FHR, should be provided in pregnant patients with vasa praevia.
107-Vasa Previa
2018, Obstetric Imaging: Fetal Diagnosis and Care: Second EditionCan we perform a prenatal diagnosis of vasa previa to improve its obstetrical and neonatal outcomes?
2017, Journal of Gynecology Obstetrics and Human ReproductionCitation Excerpt :Moreover, the lack of systematic anatomo-pathological examination of the placenta after delivery may have contributed to this undervaluation. Prenatal sonographic diagnosis of VP and elective cesarean delivery before rupture of the membranes, labor or significant bleeding are associated with excellent survival rates (reported to be 97–99%), while cases undiagnosed antenatally are subject to a disastrous outcome (fetal mortality rate is reported to be 44–100%) [1–8]. Furthermore, the antenatal identification of VP avoids us the need for blood transfusion for both fetus and mothers in all cases.
