What are placental tumors commonly associated with?

  1. Increased maternal age

  2. Higher rates of preterm labor and polyhydramnios

  3. Improved fetal development

  4. Reduced placental vascular issues

The correct answer is: Higher rates of preterm labor and polyhydramnios

Placental tumors, such as chorioangiomas, are associated with several complications that can impact pregnancy outcomes. Among these, higher rates of preterm labor and polyhydramnios are significant. The presence of a placental tumor can lead to increased blood flow through the placenta, which may cause excessive amniotic fluid accumulation (polyhydramnios) and contribute to complications associated with preterm labor. Preterm labor is often a risk factor linked to various placental abnormalities, and the overproduction of amniotic fluid can create additional stress on the uterine environment, leading to a higher likelihood of early delivery. In contrast, the option referencing improved fetal development does not align with the realities often seen in pregnancies affected by placental tumors, as these tumors can lead to various health concerns for the fetus. Similarly, while maternal age is a factor in many pregnancy conditions, its connection to placental tumors is not definitive or direct. Lastly, reduced placental vascular issues does not reflect the truth that placental tumors can indeed disrupt normal placental blood flow, leading to vascular complications rather than a reduction in such issues.
