Objective: To evaluate the association between fetal hemodynamic changes seen in the presence of vascular tumors of fetal or placental origin and risk of adverse pregnancy outcome.
Methods: All cases of placental chorioangioma, sacrococcygeal teratoma and pulmonary sequestration during a 10-year period were included. Ultrasound data and pregnancy and long-term neurodevelopmental outcomes were assessed in this cohort. A survival analysis was performed to assess the relationship between the cardiovascular profile score (CVPS) and adverse pregnancy outcome.
Results: There were 56 fetal or placental tumors, including 28 chorioangiomas, 10 sacrococcygeal teratomas and 18 pulmonary sequestrations, diagnosed at a median gestation of 23 + 3 weeks. Abnormal CVPS (≤ 8) was seen in 30% of sacrococcygeal teratomas and in 46% of chorioangiomas, but in none of the pulmonary sequestration cases. Adverse pregnancy outcome occurred in 11 cases (three stillbirths, three neonatal deaths and five cases of developmental delay) and only in those cases in which the tumors were associated with a CVPS of ≤ 8.
Conclusions: Certain fetal and placental vascular tumors are associated with cardiac dysfunction in fetal life. When the CVPS is low (≤ 8), these cases are at increased risk of both fetal/neonatal demise as well as overt long-term neurodevelopmental disability. The long-term neurodevelopmental outcome should be formally and prospectively assessed in cases of fetal and placental vascular tumors.
