What is chorioangioma of the placenta?
What is chorioangioma of the placenta?
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.
How is chorioangioma treated?
The combined use of bipolar cautery with a diode laser proved to be an effective treatment option for symptomatic chorioangioma. With bipolar cautery, surgeons were able to reduce the blood flow to the chorioangioma by coagulating the main feeding vessel, which was too large to be safely coagulated by the laser diode.
What is placental hydrops?
Abstract. Fetoplacental hydrops is the final stage of several pathological conditions in which the placenta and umbilical cord become edematous and the fetus develops an anasarcatic state characterized by an excessive accumulation of extravascular fluids in at least two serous cavities of the body.
How is chorioangioma diagnosed?
Diagnosis of chorioangioma is made through ultrasound. Ultrasound is considered as a safe radiology test during pregnancy and is therefore a preferred imaging test. A color Doppler test, which studies the blood flow through the tumor, is useful in conditions where a definite diagnosis with ultrasound is difficult.
How do you get Chorioamnionitis?
What causes chorioamnionitis? Chorioamnionitis is most often caused by bacteria commonly found in the vagina. It happens more often when the bag of waters (amniotic sac) is broken for a long time before birth. This lets bacteria in the vagina move up into the uterus.
What is VCI pregnancy?
Introduction: A velamentous cord insertion (VCI) describes a peripheral umbilical cord insertion to the placenta with blood vessels from the cord traversing fetal membranes before reaching the placental margin. These vessels remain unprotected and exposed to pressure and injury during pregnancy and labor.
Can a baby survive with hydrops?
The severe swelling that occurs with hydrops can overwhelm the baby’s organ systems. About 50% of unborn babies with hydrops don’t survive. Risks for other problems are also high for babies born with hydrops.
Can hydrops resolve?
Spontaneous resolution of Non-immune Hydrops fetalis. A case report of hydrops fetalis characterized by ascites and scalp edema of unknown etiology is described. The hydrops developed at 24 weeks and resolved completely without treatment resulting in a live born infant at term. KEY WORDS: Hydrops Fetalis.
What is hydrops?
Hydrops fetalis—or hydrops—is a condition in which large amounts of fluid build up in a baby’s tissues and organs, causing extensive swelling (edema).
What happens when a baby has a chorioangioma?
A chorioangioma is thought to arise as a malformation of the tissue of the placenta. As it grows, the tumor acts as a shunt between fetal arteries and veins leading to progressive heart failure in the baby if the condition is left undetected.
How big does a chorioangioma lesion need to be?
In general, lesions larger than 4 cm are considered to produce hemodynamic effects on the fetus 3. Therapeutic amnio-drainage is an option if there is excessive polyhydramnios. Vascular shunting may cause fetal high-output cardiac failure and hydrops fetalis.
When to induce labor with a chorioangioma?
Earlier if there is evidence of poor growth, fetal hypoxia or hydrops. Method: induction of labor aiming for vaginal delivery, unless the fetus is hydropic and hypoxic. Symptomatic chorioangiomas carry a high risk of perinatal death. The neonate may have severe microangiopathic hemolytic anemia and thrombocytopenia. No increased risk of recurrence.
Where can you see the chorioangioma on ultrasound?
Ultrasound. often seen as a hypoechoic, rounded mass, located near the chorionic plate +/- umbilical cord insertion site it usually contains anechoic ‘cystic’ areas and can be seen as distinctly separate to normal surrounding placental tissue.
