Q

Why is ectopic an emergency?

A
  • Pregnancy can outgrow the space and rupture it, causing intra-abdominal bleeding
  • Fallopian tube supplied by ovarian artery, direct branch of aorta
  • First presentation might be catastrophic collapse

16
Q

Medical management of ectopic, indications:

A
  • Gestational sac <35mm, no foetal heart beat, bHCG <1500IU

- Methotrexate IM 50mg – measure bHCG on day 4 and 7

17
Q

Surgical management of ectopic, indications:

A
  • If gestational sac >35mm, foetal heart beat, bHCG>5000
  • If unstable and unsuitable for outpatient care, or haemoperitoneum
  • Surgery: open, or laparoscopic – salpingectomy, salpingotomy
18
Q

Gestational trophoblastic disease:

A

Partial or complete hydatidiform mole – abnormal pregnancy from the conception (imbalance of maternal and paternal genetic material). Risk of abnormal tissue persisting and causing cancer.

19
Q

Complete mole symptoms:

A
  • Snowstorm appearance on US
  • Irregular bleeding, large uterus
  • High BhCG levels
  • No foetus
20
Q

Partial mole:

A
  • Foetal pole and cystic placenta
  • Mimics a missed miscarriage
  • hCG can be normal
21
Q

Gestational Trophoblastic Neoplasia:

A
  • Invasive mole
  • Choriocarcinoma
  • Placental site trophoblastic tumour
22
Q

Risk factors for trophoblastic neoplasia:

A
  • Extremes of age
  • Asian (Korean and Japanese)
  • Previous gestational trophoblastic disease
23
Q

Management of trophoblastic neoplasia:

A
  • ERCP
  • Products sent to histopathology, registered with Central Unit (CX)
  • Monitor HCG for 6 months after normalised,
  • Chemotherapy if persistently high
  • Avoid pregnancy until follow up
24
Q

Anti D use in early pregnancy:

A
  • Bleeding post 12 weeks
  • Surgical instrumentation of uterus
  • Ectopic pregnancy
  • Termination
  • Miscarriage
  • Molar pregnancies
25
Q

Recurrent miscarriage:

A
  • Loss of 3 or more consecutive pregnancies
26
Q

Reasons for recurrent miscarriage:

A
  • Alcohol drinking
  • PCOS (insulin resistance)
  • Poorly controlled diabetes
  • Antiphospholipid syndrome
  • Protein C resistance or protein S deficiency
  • Uterine abnormality (septate, arcuate uterus)
  • Cervical weakness (2nd trimester loss)
27
Q

Investigations in recurrent miscarriage:

A
  • Antiphospholipid antibodies
  • Thrombophilia screen
  • 3rd and any next products of conception – cytogenetics
  • Pelvic USS and hysteroscopy
28
Q

Management of recurrent miscarriage:

A
  • Stop smoking, Weight loss, Take folic acid
  • Antiphospholipid syndrome: aspirin and heparin
  • Thrombophilia: heparin (Reduces 2nd trimester miscarriage)
  • Uterine septum resection
  • Cervical incompetence: suture if 3 or more 2nd trimester loss
  • Cervical length screening: if 1 or more 2nd trimester loss
