Abstract
Chorioangiomas are the most frequently occurring type of benign tumour of the placenta. However, large chorioangiomas greater than 4 cm are rare and can be more frequently associated with serious complications such as: polyhydramnios, hydrops fetalis, fetal anaemia, intrauterine growth restriction, preterm birth, and an increased risk of perinatal mortality. Importantly timely prenatal diagnosis with close surveillance alongside potential intrauterine intervention can prove impactful on pregnancy outcome and fetal survival.
We present a case of a 36-year-old female referred to our tertiary fetal medicine unit at 28 weeks’ gestation with a large chorioangioma measuring 9.4×8.8×5.5 cm and ultrasonographic evidence of severe fetal anaemia and fetal hydrops. The patient underwent an intrauterine transfusion and in utero surgical therapy with radiofrequency ablation (RFA). Immediately following the procedure, the fetus sustained a period of bradycardia, followed by asystole. Delivery was expedited via emergency caesarean section. Careful planning and rapid delivery after fetal intervention within the most appropriate surgical setting mitigated risks for the baby and resulted in a positive outcome. The baby was discharged from the neonatal unit on day 84 of life.
Large placental chorioangiomas are a rare occurrence, however, when associated with fetal complications present a high incidence of adverse perinatal outcomes. In utero interventions require careful planning and surgical expertise to ensure improved fetal and neonatal outcomes. To the best of our knowledge this case is the first recorded instance of a successful postnatal outcome following RFA for a large placental chorioangioma, whereby the fetus was complicated by fetal hydrops.
期刊介绍:
Case Reports in Perinatal Medicine is a double-blind peer-reviewed journal. The objective of the new journal is very similar to that of JPM. In addition to evidence-based studies, practitioners in clinical practice esteem especially exemplary reports of cases that reveal specific manifestations of diseases, its progress or its treatment. We consider case reports and series to be brief reports describing an isolated clinical case or a small number of cases. They may describe new or uncommon diagnoses, unusual outcomes or prognosis, new or infrequently used therapies and side effects of therapy not usually discovered in clinical trials. They represent the basic concept of experiences for studies on representative groups for further evidence-based research. The potential roles of case reports and case series are: Recognition and description of new diseases Detection of drug side effects (adverse or beneficial) Study of mechanisms of disease Medical education and audit Recognition of rare manifestations of disease.
