What is a chorioangioma of the placenta?
What is a chorioangioma of the placenta?
Abstract. Placental chorioangioma is the most common benign non-trophoblastic tumor of the placenta. It is derived from primitive chorionic mesenchyme and is typically vascular. Placenta chorioangiomas occur in approximately 1% of pregnancies. Most placental chorioangiomas are small and are not clinically important.
What causes placental chorioangioma?
The cause of chorioangioma is unknown. The abnormal masses form in the chorionic tissue, the tissue on the fetal side of the placenta. Chorioangiomas occur in an estimated 1% of pregnancies. The tumors are seen more often in pregnancies where the fetus is female and in those involving multiples (twins, triplets, etc.).
What does a mass on the placenta mean?
Chorioangioma is a benign tumor of placenta. It is seen in approximately 0.5 to 1% pregnancies. It is mostly diagnosed ultrasonically in the second trimester of pregnancy. Large chorioangiomas are known to cause complications in pregnancy, while the smaller ones are asymptomatic.
What is a chorioangioma?
Chorioangioma is a benign vascular malformation of the placenta and represents the most common primary tumour of the placenta. Presence of this vascular malformation can result in significant maternal and fetal morbidity depending on the size of the lesion.
What is the most common lesions of placenta?
The angiomatous is the most common, with numerous small areas of endothelial tissue, capillaries, and blood vessels surrounded by placental stroma. These lesions are sometimes classified as placental hamartomas rather than true neoplasia.
What is the most common placental tumor?
Placental chorioangioma is the most common type of placental tumor. It is usually symptomless and may be associated with serious maternal and fetal complication when it reaches a large size.
How is the tumor of placenta diagnosed?
Ultrasound scan is the method of choice to detect placental tumors. Serial ultrasound scans were necessary to monitor the amount of the amniotic fluid and to detect possible complication. Histological examination confirmed the benign form of the placental tumor and no more investigations are needed for the mother.
What causes Succenturiate placenta?
Independent risk factors for succenturiate placenta were gestational age, prepregnancy BMI, pelvic infection, prior cesarean section, infertility, and preeclampsia.
Is Succenturiate placenta high risk?
Conclusion: The results suggest that the incidence of succenturiate placenta increases along with an increase in pelvic infection, infertility, and preeclampsia. The condition of succenturiate placenta increases the risks for prematurity, impaired fetal growth, and cesarean delivery.
What is meant by Succenturiate placenta?
Placenta succenturiate is a morphological abnormality of the placenta where one or more of the lobes are present outside the placental body. These can have different sizes and are connected by blood vessels to the main placenta.
What is placenta Succenturiate?
The succenturiate placenta is a condition in which one or more accessory lobes develop in the membranes apart from the main placental body to which vessels of fetal origin usually connect them. It is a smaller variant of a bilobed placenta.
When your placenta is over your cervix?
Placenta previa (pluh-SEN-tuh PREH-vee-uh) occurs when a baby’s placenta partially or totally covers the mother’s cervix — the outlet for the uterus. Placenta previa can cause severe bleeding during pregnancy and delivery. If you have placenta previa, you might bleed throughout your pregnancy and during your delivery.
How is the placenta connected to a chorioangioma?
A chorioangioma is a benign tumor made up of too many blood vessels that form in the placenta. These vessels may be connected to the baby via the umbilical cord. Although development of a chorioangioma during pregnancy is not uncommon, large chorioangiomas are rare. What is Chorioangioma?
How big is a chorioangioma in a fetus?
If the chorioangioma is large, measuring more than 4 cm, in some cases it can pose serious risks to the pregnancy and the fetus, including fetal heart failure. The cause of chorioangioma is unknown. The abnormal masses form in the chorionic tissue, the tissue on the fetal side of the placenta. Chorioangiomas occur in an estimated 1% of pregnancies.
Which is the most common tumor of the placenta?
Chorioangioma, originally described by Clarke in 1798, is the most common tumor of the placenta, with reported prevalence of approximately 0.5%–1.0% (, 1 ). Most chorioangiomas are small and are found incidentally at screening obstetric US examinations.
When to seek prenatal care for chorioangioma?
The management of pregnancies diagnosed with placental chorioangioma is mostly expectant. Prenatal intervention may be necessary in cases presenting with severe polyhydramnios, pending or overt fetal heart failure, or maternal symptoms of cervical shortening or preterm labor, particularly if remote from viability.
