Q

Classifications of uterine rupture (2)

A
  • Incomplete uterine rupture:

* Complete uterine rupture:

21
Q

Incomplete uterine rupture (def)

A

• Rupture extends through the endometrium, myometrium but the peritoneum surrounding the uterus remains intact

22
Q

Complete uterine rupture (def)

A

• Extends through the entire uterine wall (endometrium, myometrium and peritonium) and uterine contents spill into the abdominal cavity

23

25
Q

Adherent placenta – 3 types / levels

A
  • Acreta
  • Increta
  • Percreta
26
Q

Placenta acreta

A

Slight penetration of myometrium (A-creta = A-little penetration)

27
Q

Placenta increta

A

Deep penetration of myometrium (In-creta = In- deep)

28
Q

Placenta percreta

A

Complete perforation of the uterus (Per-creta = Per-foration)

29
Q

Retained placenta: Predisposing factors (3)

A
  • Abnormal site of implantation (placenta grabs onto something abnormal)
  • Malformation of the placenta (not as common)
  • Scarring of the uterus
30
Q

What would cause scarring of the uterus? (4)

A
  • High parity (scarring of the uterus)
  • Previous cesarean section (scarring)
  • Previous myomectomy (from removal of fibroids)
  • Hx of vigorous curettage / perforation (scraping the lining)
31
