“…The most common locations of umbilical cord rupture were umbilical veins (67%) and umbilical arteries (13%) [4] . According to the degree of rupture, umbilical cord rupture can be either partial or complete.…”

Background: Spontaneous umbilical cord vascular rupture is a rare but catastrophic event during pregnancy, and the perinatal mortality rate is extremely high. Live neonates may have severe asphyxia and require admission to the neonatal intensive care unit for many days. Methods: A retrospective review of the clinical data of eleven patients with spontaneous umbilical cord vascular rupture from 2012 to 2020, was undertaken at our hospital. Results: All patients were diagnosed by postpartum placental examination and pathological examination. The Obstetric Rapid Response Team performed emergency cesarean sections in fetal distress patients, and the time between detection of fetal heart abnormality and delivery was 5 to 13 minutes. Eight patients had bloodstained amniotic fluid and one had III° foul amniotic fluid. Six patients had the umbilical cord around their necks. Furthermore, pathological examination of postpartum placentas found four cases of intrauterine infection.Among the eight live neonates, one neonate died two days after birth due to severe complications and one had neonatal hyperbilirubinemia. No neurological sequelae, or other severe complications were found in the remaining seven neonates after three months of follow-up, and all of them had a positive prognosis.Conclusion: Spontaneous umbilical cord vascular rupture is a serious risk for perinatal birth life and obstetric complications. For this reason, obstetricians should be familiar with and pay attention to its risk factors.

Background Spontaneous umbilical cord vascular rupture(UCVR)is a rare but catastrophic event, and may lead to fetal blood loss and severe perinatal morbidity and mortality. UCVR remains difficult to diagnose, so when it happen, the effective treatment is a key to improve the pregnancy outcomes.UCVR as an obstetric emergency situation especially for neonate, whether rapid response team(RRT) could have effectiveness on the pregnancy outcomes is rare reported. Methods A retrospective cohort study of twelve patients with spontaneous UCVR from 2012 to 2022 were undertaken. Data and images of UCVR were collected via the electronic case system.Demographic and clinical characteristics were collected by researchers. Results Twelve patients were diagnosed by postpartum placental examination and pathological examination. The mean age of participants was (29.67 ± 3.75) years, the mean BMI was (20.48 ± 2.43)kg/m2, the mean gestational age at which rupture occurred was (37.33 ± 2.61)weeks. The decision to delivery interval(DDI) was from 5 to 15 minutes.2 of them were marginal umbilical cord insertion, 5 were velamentous insertion. 9 cases were bloody amniotic fluid. Although all the umbilical cord lengths were within the normal range (38–70 cm), 5 had the umbilical cord around their necks. 10 were vein rupture, 1 was artery and 1 was both atery and vein rupture. About the pregnancy complications, mainly complicated with fetal distress,premature rupture of the membranes(PROM) ,anemia, velamentous cord insertion(VCI), GDM and racket placenta. 6 of them with abnormal placental insertion. all the neonates were admitted to the neonatal intensive care unit (NICU)for 1 to 63 days. Except for one case of stillbirth during the vaginal labour, there were 11 livebirths who underwent cesarean section. One died two days after birth due to severe complications.They were mainly complicated with hypoxic ischemic encephalopathy(HIE),severe neonatal asphyxia and neonatal pneumonia. But with a well prognosis after more than 1 year’s follow-up. Conclusions Early identification of spontaneous UCVR by FHR and character of amniotic fluid during labour is important. Once vascular rupture occurs, obstetric RRT should be activated and the emergency CS should be performed with shorter DDI to reduce perinatal mortality.

Spontaneous intrauterine umbilical cord vascular rupture is an uncommon, unpreventable, and dangerous event. Once it occurs, there is little chance to intervene, and often with a poor perinatal outcome. A 32-year-old primiparous woman at 40 weeks of gestation with a normal pregnancy presented to the emergency room because of vaginal fluid. During induction of labor with oxytocin, the fetal heart rate declined. An emergency cesarean delivery was carried out. Breach of branch of umbilical vein was noted. The neonate underwent urgent treatment, and was discharged on day 10 without apparent sequelae. It is a rare case of a spontaneous umbilical cord vascular rupture with a viable birth because of congenital defects of umbilical cord. When an unexpected drop in the fetal heart is observed, umbilical cord vascular rupture must be suspected, and emergency correct intervention can lead to a live birth.
