Partial mole: triploid tissue; variable evidence of a fetus
- Usually two sperm fertilise a haploid oocyte; typically 69XXY
How do you manage a molar pregnancy?
- Complete mole: suction curettage (ERPC). Anti-D prophylaxis is not required.
- Partial mole: suction curettage (ERPC), unless size of the fetal parts deters this and then medical evacuation can be used but avoid where possible (potential risk of increasing trophoblastic embolisation by inducing uterine contractions). Anti-D prophylaxis is required.
- Serial blood or urine hCG levels taken thereafter
- Register with supraregional centre who guide follow-up
- Avoid pregnancy until after completion of suveillance period
Where is human chorionic gonadotropin produced?
The human placenta by the syncytiotrophoblast
What is the role of human chorionic gonadotropin?
It promotes the maintenance of the corpus luteum during the beginning of pregnancy. This allows the corpus luteum to secrete the hormone progesterone during the first trimester.
What is the role of progesterone?
Progesterone:
- Enriches the uterus with a thick lining of blood vessels and capillaries so that it can sustain the growing fetus (secretory stage)
- Decreases uterine contractility
- Inhibits lactation
What level of progesterone suggests an intrauterine pregnancy?
> 60 nmol/l
<20 nmol/l = non-viable pregnancy
