Trisomy 18 (Edwards syndrome) and major gastrointestinal malformations

Hirschsprung disease with Edward syndrome: A rare association: A case report

INTRODUCTION AND IMPORTANCE

Edward's syndrome (ES) occurs as a result of trisomy of chromosome 18 and is associated with multisystem congenital anomalies. The association of ES with various gastrointestinal malformations but Hirschsprung disease (HD) is well documented.

CASE PRESENTATION

A female infant on her 5th day of life presented with episodes of bilious vomiting along with abdominal distension and no passage of stool. The child had a small head and prominent occiput, low set abnormal ears, small jaw, upturned nose, widely spaced eyes, small neck with widely spaced nipples, clenched hands with overlapping fingers, flexed big toe, and prominent heels.

CLINICAL DISCUSSION

Edward syndrome is associated with multisystem congenital abnormalities of which gastrointestinal abnormalities make up the most part. The condition can be identified by fetal ultrasound screening. Surgical correction of associated congenital anomalies at different times along with lifelong supportive management is important.

CONCLUSIONS

Edward syndrome can present as Hirschsprung disease as a part of associated gastrointestinal Malformation. Often, early identification and termination of the pregnancy in antenatal life can reduce the suffering. Surgical correction of associated anomalies along with supportive care forms the cornerstone of management. However, the prognosis remains poor.

Hypoxia due to positive pressure ventilation in Edwards' syndrome: A case report

Edwards’ syndrome also known as trisomy 18 is a congenital disorder associated with cardiovascular issues including ventricular septal defect (VSD), atrial septal defect (ASD) and patent duct arteriosus (PDA). An emergency colostomy was performed on a neonate born with an imperforate anus. Pre-operative transthoracic echocardiography showed presence of VSD, a patent foramen ovale (PFO) or ASD. Even though the baby had a good general condition and optimal peripheral oxygen saturation (SpO₂), during positive pressure ventilation, she suffered severe hypoxia (50% SpO₂). The cause of the hypoxia was thought to be the right-left shunt and so during a second attempt at anaesthesia a vasopressor (noradrenaline 0.03 µg/kg/min) was infused to increase systemic vascular resistance. Thereafter, SpO₂ increased to 80–90% and the surgery was completed. The baby recovered without any neurological complications. Genetic testing post-partum showed she had Edwards’ syndrome.

Obstetric practice patterns in pregnancies complicated by fetal trisomy 13 or 18

PURPOSE

Describe practice patterns among obstetrician/gynecologists (OB/GYNs) when caring for women with pregnancy complicated by fetal trisomy 13 (T13) or 18 (T18) and compare these between maternal-fetal medicine (MFM) and non-MFM providers.

MATERIALS AND METHODS

We conducted an electronic survey using the American College of Obstetricians and Gynecologists database. Using simple statistics, we describe demographics and practice patterns among respondents and compare those of MFM practitioners with non-MFM providers.

RESULTS

The survey was sent to 300 individuals, 161 individuals verified email receipt, and 105 had complete response and were included. The median age was 58 (IQR 53,62). Sixty percent were female, 69% were private practice, and 38% were MFM. All providers were more likely to offer than to recommend antenatal and intrapartum interventions. MFMs were more likely to offer growth ultrasounds and neonatal hospice consults (53% vs. 29%, p = .02; 88% vs. 60%, p < .01). During labor, MFMs were more likely offer no fetal heart rate monitoring, (90% vs. 52%, p < .01), 60% of all providers offer breech vaginal delivery; 32% offer cesarean delivery for fetal distress.

CONCLUSION

Many providers offer antepartum and intrapartum interventions for pregnancies complicated by T13/18. We recommend that providers elicit each woman's goals for pregnancies complicated by T13/18 and tailor management options to meet these goals.
