Is chorioangioma serious?
In the majority of cases the tumor is benign (noncancerous). Small chorioangiomas typically cause no symptoms and complications. 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.
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 are the anomalies of the placenta and cord?
Some of the placental and umbilical cord abnormalities found in twin gestations are nonspecific and can be found in singleton gestations (ie, placenta previa, placental abruption, single umbilical artery, velamentous cord insertion, vasa previa, etc).
What is the most common lesion of placenta?
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.
What causes a growth on the placenta?
Chronic placental insufficiency is the commonest cause for fetal growth restriction. Rare placental causes affecting fetal outcome are partial mole, chorioangioma, and placental teratoma. Large chorioangioma has adverse effects on both mother and fetus.
What does a mass on the placenta mean?
Placental mass protruding into the amniotic cavity. 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 considered a large chorioangioma?
Giant chorioangiomas, greater than 4-5 cm in diameter, are rarely seen in obstetric practice, occurring in approximately 1 in 10000 pregnancies [7].
What is the abnormalities of placenta?
Normally, the placenta attaches at the top or side of the uterus. In some cases, the placenta develops in the wrong location or attaches itself too deeply into the uterine wall. These placental disorders are called placenta previa, placenta accreta, placenta increta or placenta percreta.
What causes placental abnormality?
abdominal trauma, such as from a fall or blunt trauma. maternal age, as women over the age of 40 years have a higher risk of developing placental problems. premature rupture of membranes, because the risk of placental problems increases when the amniotic sac ruptures too early.
What is placenta cyst?
Definition: Placental cysts are sonolucent areas that can be detected antenatally by ultrasound; they have a round or oval cavity, usually isolated from the placental circulation and contain a gelatinous fluid.
What does a growth on the placenta mean?
Placental chorioangiomas are benign vascular tumours and are the most common placental tumours, with a prevalence of 1%. Large placental chorioangiomas are rare and may lead to pregnancy complications and poor perinatal outcomes.
