Causes and risk factors. One cause of vasa previa is an umbilical cord abnormality called velamentous cord insertion. This is when the umbilical cord goes into the membranes, resulting in vessels that are unprotected leading to the placenta. Another cause is bilobed placenta, where the placenta is in two pieces.
What is a bilobed placenta and what causes it?
A bilobed placenta is known to occur in about 2 to 8 % of pregnancies. No distinctive racial, ethnic or geographical tendency has been observed yet. Certain risk factors have been linked to a bilobed placenta are: An advanced maternal age, usually, when the woman is more than 35 years of age. A history of infertility.
What are the complications of a bilobed placenta?
Complications due to a Bilobed Placenta could include: Increased chances of post-partum hemorrhage due to retained placental tissue. Increased incidence of Vasa Previa: In Vasa Previa, the fetal blood vessels run over the maternal cervix with an increased risk of rupture and bleeding.
What causes placenta accreta?
Placenta accreta. Overview. Placenta accreta Placenta accreta occurs when the placenta grows too deeply into the uterine wall during pregnancy. Scarring in the uterus from a prior C-section or other uterine surgery may play a role in developing this condition.

Should I worry about a bilobed placenta?
While there is no increased risk of fetal anomalies with this abnormality, bilobed placentas can be associated with first-trimester bleeding, polyhydramnios, abruption, and retained placenta. A placenta with more than two lobes is rare and is termed a multilobate placenta.
What causes a double placenta?
It's possible for more than one placenta to form – for example, if you are pregnant with twins or triplets. This is the most common reason to have two placentas in pregnancy. Multiple pregnancies are becoming more common due to the increase in fertility treatments and because women are having babies later in life.
Is bilobed placenta genetic?
A bipartite placenta in one pregnancy may be followed by greater-than-expected frequency of bipartite placenta in the next pregnancy. This raises the possibility that some multilobed placentas have genetic origin.
What does a double lobe placenta mean?
A bilobed placenta also referred to as bipartite placenta, is a variation in placental morphology and refers to a placenta separated into two near equal-sized lobes. If more than two lobes are present, it is termed a trilobed, four-lobed and so on.

Two placentas are rare in pregnancies, including succenturiate pla- cental [1]. Two placentas with fused umbilical cord forming 3 ves- sels cord at the fetal end which has its own insertion site to each placental disc is an extremely rare case in a singleton pregnancy.
How can I improve my placenta health?
The recommended intake of iron almost doubles during pregnancy. As such, iron rich foods such as spinach, broccoli and kale are crucial during pregnancy. Low levels of iron could result in a deficiency and hinder the transfer of oxygen and nutrients to the placenta.
What causes placenta abnormalities?

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.
How many placenta does a woman have?
The placenta attaches to the uterine wall and connects to your baby via the umbilical cord. It also contains the same genetic material as your baby. Your baby has just one placenta, although you may have two placentas if you're pregnant with twins. If you have fraternal twins, each baby will have its own placenta.
How common is a vanishing twin?
According to one study, about 36% of twin pregnancies experience vanishing twin syndrome. It also occurs in around half of multiple pregnancies, or pregnancies where a woman carries more than one baby.
What Are The Causes Of Bilobed Placenta?
A bilobed placenta is known to occur in about 2 to 8 % of pregnancies. No distinctive racial, ethnic or geographical tendency has been observed yet.

What is the placenta in Salina?
Salina Pregnancy April 6, 2017. The placenta is a very vital organ which connects the developing fetus to the uterus via the umbilical cord. The umbilical cord has 1 umbilical vein and 2 umbilical arteries.
What is the function of the placenta?
The placenta supplies nutrients and oxygen to the fetus from the mother’s blood and gets rid of wastes from the fetal body. A bilobed placenta is a deviation from the normal shape of a placenta; such a placenta is split into two halves.
Why is antenatal care important?
Correct ante-natal care is very vital to make sure that you have a healthy pregnancy and an uncomplicated delivery.

What is an antenatal ultrasound?
Antenatal ultrasound. May be sonographically seen as two separate placental discs of nearly equal size. The cord usually attaches to a thin connecting rim of chorionic tissue which bridges the two lobes. Less commonly the cord may insert into one of the lobes.
Where is the placenta located?
When the placenta is located on the anterior wall, clinicians should pay attention to the adverse pregnancy outcomes and the possibility of massive postpartum hemorrhage. In cases of placental attachment to the uterine incision site, physicians should be highly vigilant regarding the occurrence of PAS disorders.".
Why is the placenta important?
As the fetus relies on the placenta for not only nutrition, but many other developmentally essential functions, the correct development of the placenta is important to correct embryonic and fetal development.
What are the abnormalities of the placental cord?
Abnormalities can range from anatomical associated with degree or site of inplantation, structure (as with twinning), to placental function, placento-maternal effects ( pre-eclampsia, fetal erythroblastosis) and finally mechanical abnormalities associated with the placental (umbilical) cord.

What is the placenta? What function does it serve?
Review - Defense and infection of the human placenta "The placenta functions as a shield against infection of the fetus. The innate and adaptive immune defenses of the developing fetus are poorly equipped to fight infections. Infection by bacteria, viruses, and protozoa may cause infertility, spontaneous abortion, stillbirth, growth retardation, anomalies of development, premature delivery, neonatal morbidity, and mortality. However, appreciation of the human microbiome and host cell-microbe interactions must be taken into consideration as we try to determine what interactions are pathologic. Infection is typically recognized histologically by the presence of inflammation. Yet, several factors make comparison of the placenta to other human organs difficult. The placenta comprises tissues from two persons, complicating the role of the immune system."
What organ is the placenta?
The placenta is a mateno-fetal organ which begins developing at implantation of the blastocyst and is delivered with the fetus at birth. As the fetus relies on the placenta for not only nutrition, but many other developmentally essential functions, the correct development of the placenta is important to correct embryonic and fetal development.
Why is my placenta accreta sore?
Placenta accreta is thought to be related to abnormalities in the lining of the uterus, typically due to scarring after a C-section or other uterine surgery. Sometimes, however, placenta accreta occurs without a history of uterine surgery.
What are the risks of a placenta accreta?
Placenta accreta can cause: 1 Heavy vaginal bleeding. Placenta accreta poses a major risk of severe vaginal bleeding (hemorrhage) after delivery. The bleeding can cause a life-threatening condition that prevents your blood from clotting normally (disseminated intravascular coagulopathy), as well as lung failure (adult respiratory distress syndrome) and kidney failure. A blood transfusion will likely be necessary. 2 Premature birth. Placenta accreta might cause labor to begin early. If placenta accreta causes bleeding during your pregnancy, you might need to deliver your baby early.
