What is an incomplete molar pregnancy?

What is an incomplete molar pregnancy?

In a partial or incomplete molar pregnancy, the mother’s chromosomes remain but the father provides two sets of chromosomes. As a result, the embryo has 69 chromosomes instead of 46. This most often occurs when two sperm fertilize an egg, resulting in an extra copy of the father’s genetic material.

What is the difference between a complete and incomplete hydatidiform mole?

In complete hydatidiform mole, there is no fetal tissue present; in partial hydatiform moles, there is some residual fetal tissue. Both are due to the over-proliferation of chorionic villi.

How long after a molar pregnancy Can you try again?

The risk of having another molar pregnancy is small (about 1 in 80). It’s best not to try getting pregnant again until all your follow-up treatment has finished. For most women, this will take about 6 months. If you have GTN, you will need to wait for 12 months after you have finished chemotherapy treatment.

What is a partial hydatidiform mole?

A partial molar pregnancy is a variation of a molar pregnancy, an abnormal pregnancy in which an embryo (the fertilized egg) either develops incompletely, or doesn’t develop at all. Instead, a cluster of grape-like cysts (known as a hydatidiform mole) grows in the uterus.

Can you naturally miscarry a molar pregnancy?

A molar pregnancy will not be able to survive. It may end on its own, with a miscarriage. If this does not happen, it’s usually treated with a procedure to remove the pregnancy. You’ll usually be given a general anaesthetic before the procedure, so you’ll be asleep.

Can a baby survive a partial molar pregnancy?

The incidence of a normal live fetus and a partial molar placenta is extremely rare. Although triploidy is the most frequent association, a fetus with normal karyotype can survive in cases of partial molar pregnancy.

What happens if you get pregnant after a partial molar pregnancy?

They usually do this about 6 to 8 weeks after any pregnancy, including miscarriage. Most women (more than 98%) who become pregnant after a molar pregnancy will not have another molar pregnancy. There is also no increased risk of complications in future pregnancies.

Is molar pregnancy genetic?

Molar pregnancies are caused by an imbalance in genetic material (chromosomes) in the pregnancy. This usually occurs when an egg that contains no genetic information is fertilised by a sperm (a complete molar pregnancy), or when a normal egg is fertilised by two sperm (a partial molar pregnancy).

Is pregnancy test positive with molar pregnancy?

Women with a molar pregnancy will have a positive pregnancy test and the same early symptoms of a normal pregnancy. In the absence of medical intervention or diagnosis, the pregnancy might seem normal for the first three to four months.

How long does it take for hCG levels to drop after a partial molar pregnancy?

In most women the levels of hCG drop fairly rapidly. Once your hormone level reaches zero for three weeks, follow-up will cease for those with a partial mole. For women with a complete mole, you will progress to monthly blood tests for a further six months.
