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.).
How do you treat chorioangioma?
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.
How does chorioangioma cause Polyhydramnios?
The large surface area of the enlarged vessels of the angioma may also predispose to the increased transudation. Polyhydramnios also can be explained by the partial placental insufficiency caused by shunting of the fetal blood into the vessels of the chorioangioma.
What is the most common lesions of placenta?
Placental chorioangiomas are benign vascular tumors of placental origin. It is the most common tumor of the placenta and is usually found incidentally.
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.
What is the meaning of chorioangioma?
Chorioangioma is a benign angioma of placenta arising from chorionic tissue. Large chorioangioma has unfavourable effects on both mother and fetus. We describe a case with large chorioangioma that had a poor outcome on the fetus.
What is placenta cyst?
Placental cyst refers to a simple cystic lesion that develops in relation to the placenta.
What role does the placenta play?
The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby’s blood. The placenta attaches to the wall of your uterus, and your baby’s umbilical cord arises from it.
How does multiple pregnancy cause Polyhydramnios?
Acute polyhydramnios in the second trimester is a typical complication in monozygous twin pregnancies. It is caused by a feto-fetal transfusion with anemia on the donor and polycythemia on the recipient twin. Contrary to the chronic hydramnios, there is no increase in malformations.
What is a Circumvallate placenta?
Complete circumvallate placenta was defined as a placenta satisfying the following criteria: the chorionic plate, which is on the fetal side of the placenta, is smaller than the placental basal plate, which is located on the maternal side; the periphery is uncovered; and the fetal surface of such a placenta presents a …
What is transfusion syndrome?
Twin-to-twin transfusion syndrome (TTTS) is a rare pregnancy condition affecting identical twins or other multiples. TTTS occurs in pregnancies where twins share one placenta (afterbirth) and a network of blood vessels that supply oxygen and nutrients essential for development in the womb.
Where is Chorion located?
yolk sac The chorion is the outermost fetal membrane around the embryo in mammals, birds and reptiles (amniotes). It develops from an outer fold on the surface of the yolk sac, which lies outside the zona pellucida (in mammals), known as the vitelline membrane in other animals.
What is placental teratoma?
Placental teratoma is a rare nontrophoblastic benign tumour, which is thought to arise from germ cells. These tumours contain elements derived from multiple germ cell layers. We report a case of teratoma, where on ultrasound; there were two echogenic masses of 4 cm × 5 cm and 3 cm × 4 cm, arising from the placenta.
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 are placenta Lakes?
Placental (venous) lakes refer to a phenomenon of formation of hypoechoic cystic spaces centrally within the placenta. Finding placental lakes during a second trimester ultrasound scan is not associated with any uteroplacental complication or with an adverse pregnancy outcome.
What is an amniotic band in pregnancy?
Amniotic band syndrome (ABS) is a rare birth defect in which bands of tissue inside the sac of fluid that surrounds a baby in the womb tangle around the baby’s body causing injury. This happens when there is a rupture in the inside sac (amnion).
Is amniocentesis a genetic test?
Genetic amniocentesis involves taking a sample of amniotic fluid and testing it for certain conditions, such as Down syndrome. Fetal lung testing. Fetal lung maturity testing involves taking a sample of amniotic fluid and testing it to determine whether a baby’s lungs are mature enough for birth.
What is the choriocarcinoma?
(KOR-ee-oh-KAR-sih-NOH-muh) A malignant, fast-growing tumor that develops from trophoblastic cells (cells that help an embryo attach to the uterus and help form the placenta). Almost all choriocarcinomas form in the uterus after fertilization of an egg by a sperm, but a small number form in a testis or an ovary.
What are the causes of Polyhydramnios?
Causes of polyhydramnios
- a twin or multiple pregnancy.
- diabetes in the mother – including diabetes caused by pregnancy (gestational diabetes)
- a blockage in the baby’s gut (gut atresia)
- an infection during pregnancy.
- the baby’s blood cells being attacked by the mother’s blood cells (rhesus disease)
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 is Accreta?
Placenta accreta is a serious pregnancy condition that occurs when the placenta grows too deeply into the uterine wall. Typically, the placenta detaches from the uterine wall after childbirth. With placenta accreta, part or all of the placenta remains attached. This can cause severe blood loss after delivery.
What is an abnormal 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.
Is cyst in placenta normal?
Conclusions: Most placental surface cysts are associated with a normal pregnancy outcome. Most such cysts are related to cystic change in an area of subchorionic fibrin. Cysts larger than 4.5 cm or more than 3 in number are more frequently associated with intrauterine growth restriction.
How common is placental cyst?
True placental cysts are rare with a prevalence of 2% to 7%. Their etiology is unknown, but they are more common in diabetes or in cases of maternofetal rhesus incompatibility. These cysts are usually asymptomatic, with the most common complication being intrauterine growth retardation.
What do hospitals do with placenta after birth?
Hospitals treat placentas as medical waste or biohazard material. The newborn placenta is placed in a biohazard bag for storage. Some hospitals keep the placenta for a period of time in case the need arises to send it to pathology for further analysis.
Does delivering the placenta hurt?
Typically, delivering the placenta isn’t painful. Often, it occurs so quickly after birth that a new mom may not even notice because she’s focused on her baby (or babies). But it’s important that the placenta is delivered in its entirety.
What is the weight of placenta?
Placenta: 1 1/2 pounds (about 0.7 kilogram) Amniotic fluid: 2 pounds (about 0.9 kilogram) Increased blood volume: 3 to 4 pounds (about 1.4 to 1.8 kilograms)
Can too much amniotic fluid harm baby?
Women with polyhydramnios may experience premature contractions, longer labor, difficulties breathing, and other problems during delivery. The condition can also cause complications for the fetus, including anatomical problems, malposition, and, in severe cases, death. Treatment aims to remove excess amniotic fluid.
