Objectives: Furcate cord insertion is a rare abnormality affecting approximately 0.1% of all pregnancies. Macroscopically, the umbilical vessels separate before reaching the placenta, lose their Wharton’s jelly, and insert at the placenta centrally, eccentrically, or marginally. The aim of this retrospective study was to determine the prevalence of furcate cord insertion more accurately, the pathological characteristics, and clinical outcomes. Methods: We conducted a retrospective study of 132 cases of furcate insertion of the umbilical cord using the pathological database of the Charité University Hospital Berlin, Germany, between 1993 and 2016. This included 99 cases, including one termination of pregnancy within our institution and 33 cases from external hospitals. An analysis of the pathological features of the 132 cases and the perinatal outcome of the 98 cases within our institution were performed. Results: Furcate cord insertion occurred in 0.16% pregnancies. Of the 132 cases, seven cases of intrauterine fetal deaths were observed. Three of those could be linked to the furcate cord insertion. In two of those cases, single umbilical vessel rupture was identified as the cause of fetal death. Conclusions: In most cases of furcate cord insertion, the outcome is good; however, intrauterine fetal death occurs in approximately 1.02% of cases.

Background: The classic mid-trimester preterm premature rupture of membranes (PPROM) is defined as a rupture of the fetal membranes prior to 28 weeks of gestation (WG) with oligo/anhydramnion; it complicates approximately 0.4–0.7% of all pregnancies and is associated with very high neonatal mortality and morbidity. Antibiotics have limited success to prevent bacterial growth, chorioamnionitis and fetal inflammation. The repetitive amnioinfusion does not work because fluid is lost immediately after the intervention. The continuous amnioinfusion through the transabdominal port system or catheter in patients with classic PPROM shows promise by flushing out the bacteria and inflammatory components from the amniotic cavity, replacing amniotic fluid and thus prolonging the PPROM-to-delivery interval. Objective: This multicenter trial aims to test the effect of continuous amnioinfusion on the neonatal survival without the typical major morbidities, such as severe bronchopulmonary dysplasia, intraventricular hemorrhage, cystic periventricular leukomalacia and necrotizing enterocolitis one year after the delivery. Study Design: We plan to conduct a randomized multicenter trial with a two-arm parallel design. Randomization will be between 22/0 and 26/0 SSW. The control group: PPROM patients between 20/0 and 26/0 WG who will be treated with antibiotics and corticosteroids (from 22/0 SSW) in accordance with the guidelines of German Society of Obstetrics and Gynecology (standard PPROM therapy). In the interventional group, the standard PPROM therapy will be complemented with the Amnion Flush Method, with the amnioinfusion of Amnion Flush Solution through the intra-amnial catheter (up to 100 mL/h, 2400 mL/day). Subjects: The study will include 68 patients with classic PPROM between 20/0 and 26/0 WG. TRIAL-registration: ClinicalTrials.gov ID: NCT04696003. German Clinical Trials Register: DRKS00024503, January 2021.

Objectives Chorioamniotic separation (CAS) at the time of standard amniocentesis (AC) is a risk factor for postprocedural complications and should be avoided. The aim of this study was to quantify procedure-related risks after AC with a 29G-needle in cases of CAS, and evaluation of perinatal outcome in CAS after 15 weeks’ gestation (GW). Methods Retrospective analysis of genetic AC with a pencil-point 29G needle after 15 completed GW in pregnancies, in which the fetal membranes were not yet fused. Included into the study were women aged 16–44 years with at least 15 completed GWs referred for second trimester AC to identify fetal chromosomal aberrations. Results 437 ACs were made in total with the 29G-needle. The median maternal age was 30 (16–44) years. 145 cases showed CAS where the distance between chorion and amnion was 0.10–10.02 mm at AC. 38 pregnancies were terminated, 37 of which had a genetic disorder. The risk of aneuploidy increases by a factor of 2 (95% CI 1.4–2.8) for every 1 mm of CAS enlargement. No procedure-related complications were found up to two weeks after the AC. Conclusions CAS seems to be massively underreported. Early diagnosis in case of CAS is something to strive for as CAS could be an indicator of genetic abnormalities – a “soft marker”. With the atraumatic 29G needle, the risk of complications after AC in CAS seems to be very low.
