OBJECTIVE: To report the perinatal outcome of singleton pregnancies complicated by placental chorioangioma diagnosed on prenatal ultrasound.

METHODS: MEDLINE, EMBASE, CINAHL and ClinicalTrials.gov databases were searched for studies reporting the outcome of pregnancies complicated by placental chorioangioma. Inclusion criteria were singleton pregnancy diagnosed with placental chorioangioma on prenatal ultrasound, with no other associated structural anomaly. The primary outcome was perinatal mortality. Secondary outcomes included associated non-structural anomalies detected on prenatal ultrasound (including fetal hydrops, anemia, polyhydramnios, signs of hyperdynamic circulation and small-for-gestational-age (SGA) fetus), SGA at birth, composite neonatal morbidity and preterm birth. Outcome was assessed separately in pregnancies undergoing and those not undergoing fetal therapy. Subanalyses were performed according to the presence of hydrops and the size of the tumor in all pregnancies diagnosed with chorioangioma. Random-effects meta-analyses of proportions were used to analyze the data.

RESULTS: Twenty-eight studies (161 pregnancies) were included. In pregnancies complicated by chorioangioma that did not undergo intervention, intrauterine death occurred in 8.2% (95% CI, 3.8-15.0%), while neonatal death and perinatal death occurred in 3.8% (95% CI, 1.0-8.1%) and 11.1% (95% CI, 5.0-19.4%), respectively. SGA at birth was present in 24.0% (95% CI, 13.5-36.5%) of cases, while preterm birth < 37 weeks complicated 34.1% (95% CI, 21.1-48.3%) of pregnancies. Composite neonatal morbidity occurred in 12.0% (95% CI, 4.5-22.3%) of cases. On ultrasound, signs of fetal hyperdynamic circulation were present in 21.0% (95% CI, 9.6-35.3%) of cases, while peak systolic velocity in the fetal middle cerebral artery was increased in 20.6% (95% CI, 10.9-32.3%). Subanalysis according to the size of chorioangioma, including both pregnancies that did and those that did not undergo intervention, showed a progressive increase in the occurrence of most of the outcomes explored with increasing size of the tumor. Furthermore, the prevalence of adverse perinatal outcome was high in pregnancies complicated by chorioangioma presenting with fetal hydrops. There was no randomized controlled trial comparing intervention vs expectant management in pregnancies complicated by chorioangioma with signs of fetal compromise (hydrops or hyperdynamic circulation). Overall, perinatal mortality occurred in 31.2% (95% CI, 18.1-46.1%) of fetuses undergoing in-utero therapy, and 57.3% (95% CI, 39.2-74.4%) had resolution of hydrops or hyperdynamic circulation after treatment.

CONCLUSIONS: Placental chorioangioma is associated with adverse perinatal outcome. The size of the mass and presence of fetal hydrops are likely to be the main determinants of perinatal outcome in affected pregnancies. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.
