Q

What is the aetiology of ectopic pregnancy?

A

Impaired migration of the fertilised ovum along the fallopian tube.
> This can be due to tubal damage/blockage or impaired movement of cilia.

Q

Recurrent miscarriage

A

3 or more consecutive losses

24
Q

Stillbirth

A

Baby dies at or after 24 weeks

25
Q

Khan Academy Implantation

A

Khan Academy Implantation

26
Q

Threatened miscarriage

A

Vaginal bleeding before 24 weeks

27
Q

Inevitable miscarriage

A

Vaginal bleeding and open cervix

28
Q

Complete miscarriage

A

Fetus and placenta passed. Empty uterus on ultrasound.

29
Q

Incomplete miscarriage

A

Retained tissue in the uterus. Fetus or part of placenta have passed.

30
Q

Silent/Missed miscarriage

A

Fetus has died or failed to develop but remains in utero

31
Q

Early fetal demise / Empty sac

A

Empty in uterus, no fetal tissue. A pregnancy without an embryo.

32
Q

Pregnancy of unknown location (PUL)

A

No identifiable pregnancy on ultrasound with a positive BHCG.

33
Q

Septic miscarriage

A

Miscarriage with infection.

34
Q

What are some of the causes of recurrent miscarriage?

A 
Maternal age
Genetic factors
Structural uterine abnormalities
Antiphospholipid syndrome
Thrombophillia
Cervical weakness
Endocrine causes
35
Q

70% of miscarriages are caused by what?

A

Sporadic chromosomal abnormalities
> random events
> unlikely to reoccur

36
Q

What are some of the structural uterine abnormalities that increases the risk of miscarriage?

A

Septate uterus
Fibroids
Adhesions in the uterine cavity

37
Q

Septate uterus

A

A septate uterus is a deformity of the uterus, which happens during fetal development before birth. A membrane called the septum divides the inner portion of uterus, at its middle. This dividing septum is a fibrous and muscular band of tissue that can be thick or thin.

38
Q

What is the effect of adhesions in the uterine cavity?

A

Asherman’s syndrome
Increases the risk of miscarriage
Can cause infertility

39
Q

Asherman’s syndrome

A

Asherman’s syndrome (AS), is an acquired uterine condition that occurs when scar tissue (adhesions) form inside the uterus and/or the cervix. In many cases the front and back walls of the uterus stick to one another.

40
Q

Antiphospholipid syndrome

A

Antiphospholipid syndrome (APS), sometimes known as Hughes syndrome, is a disorder of the immune system that causes an increased risk of blood clots. Increases the risk of DVT’s.

41
Q

How does antiphospholipid syndrome affect pregnancy?

A

Affects implantation in early pregnancy.

APS is a treatable cause of recurrent miscarriage.

42
Q

What is the treatment for people with APS?

A

Asprin / Heparin

43
Q

What type of condition is Antiphospholipid syndrome?

A

Autoimmune condition (sticky blood)

44
Q

Thrombophilia

A

Hypercoagulability - blood has an increased tendency to form clots. Known cause of systemic thrombosis.

45
Q

How can thrombophilia cause miscarriage?

A

In pregnancy thrombosis of uteroplacental circulation can cause miscarriage and fetal loss.

46
Q

Cervical weakness

A

The cervix dilates to early causing loss of the fetus - is a cause of late miscarriage.

47
Q

HbA1c

A

HbA1c is your average blood glucose levels for the past 2-3 months.

48
Q

What endocrine conditions can also cause miscarriage?

A

Diabetes mellitus

Thyroid disease

49
Q

What is the likelihood of miscarriage for a women over the age of 40?

A

50%

50
Q

When does the fetal heart start beating?

A

22 days

51
Q

Postpartum haemorrhage

A

Vaginal bleeding from the third stage of labour until the end of pueperium.

52
Q

Pueperium

A

6 weeks following delivery of baby.

53
Q

What are the risk factors of postpartum haemorrhage?

A 
Age (women over 35)
Multiple pregnancy
Women with fibroids
Placenta praevia
Long labour
54
Q

What is the main cause of secondary postpartum haemorrhage?

A

Infection of the uterine cavity (endometritis) or retained products of conception.

55
Q

Placenta previa

A

Placenta Previa is a condition where the placenta lies low in the uterus and partially or completely covers the cervix. The placenta may separate from the uterine wall as the cervix begins to dilate (open) during labor.
