Q

Placenta percreta?

A

placenta penetrates myometrium and into uterine serosa (invades entire uterine wall) –> can result in placental attachment to rectum or bladder

Q

Placenta accreta/increta/percreta - types, definition of every type and MC

A
  1. Placenta accreta (MC) –> placenta attaches to myometrium without penetrating it
  2. Placent increta –> placenta panetrates INTO myometrium

Q

Placenta accreta/increta/percreta - presentation

A
  1. often detecten on US prior to delivery

2. no separation of placenta after delivery –> postpartum bleeding (can cause Sheehan syndrome)

16
Q

Placenta previa - types

A

compete –> covers all the os

partial –> covers not the entire os

17
Q

Vasa previa?

A

fetal vessels run over, or in close proximity to, cervical os

18
Q

Vasa previa - results in

A
  1. vessel rupture
  2. exsanguination (blood loss, to a degree sufficient to cause death)
  3. fetal death
19
Q

Vasa previa - presentation

A

TRIAD

  1. membrane rupture (rupture of the amniotic sac)
  2. painless vaginal bleeding
  3. fetal bradycardia (less than 110 beats/min)
20
Q

Vasa previa - management

A

emergency C-section

21
Q

Vasa previa is frequently associated with

A

velamentous umbilical insertion

22
Q

velamentous umbilical insertion?

A

cord inserts in chorioamniotic membrane rather than placenta –> fetal vessels travel to placenta unprotected by Wharton jelly

23
Q

Postapartum haemorrhage is due to (and MC)

A 
mnemonic 4Ts
Tone uterine atony (MC)
Trauma - lacerations, incisions, uterine rupture 
Thrombin - coagulopathy 
Tissue - retaind products of conception
24
Q

uterine atony –> hemorrhage - mechanism

A

Normally, contraction of the uterine muscle compresses the vessels and reduces flow

25
Q

ectopic pregnancy - presentation

A
  1. pain (clinically mistaken by appendicitis)

2. bleeding (+/-)

26
Q

ectopic pregnancy - risk factors

A
  1. prior ectopic pregnancy
  2. history of infertility
  3. salpingitis (PID)
  4. Ruptured appendix
  5. Prior tubal surgery
27
Q

ectopic pregnancy - confirm diagnosis with

28
Q

ectopic pregnancy - suspect it when

A
  1. history of amenorrhea
  2. lower tha excpected rise in hCG (based on dates)
  3. sudden lower abdominal pain
29
Q

ectopic pregnancy - most often area

A

Ampulla of fallopian tube

30
Q

treatment of an ectopic pregnancy is necessary to

A

prevent serious , even life threatening complications

31
Q

Amniotic fluid abnormalities - types and defintion

A
  1. Polyhydramnios: too much amniotic fluid

2. Oligohydramnios: too little amniotic fluid

32
Q

causes of polyhydramnions

A
  1. fetal malformations (eg. esophageal/duodenal atresia, anencephaly –>both inability to swallow amniotic fluid)
  2. maternal diabetes
  3. fetal anemia
  4. multiple gestations
33
Q

causes of oligohydramnios

A
  1. placental insuficiency
  2. bilateral renal agenesis
  3. posterior urethral valves (males)
  4. ARPKD
    (inability to excrete urine)
34
Q

oligohydramnios - complications

A

POTTER sequence

35
Q

Potter sequence (syndrome) - presentation

A
  1. limb deformites
  2. facial anomalies (low set ears, retrognathia, flattened nose)
  3. pulmonary hypoplasia
