Couvelaire uterus (uteroplacental apoplexy) is most specifically associated with which complication of pregnancy?
- A Placenta previa with massive hemorrhage
- B Rupture of marginal sinus
- C Severe placental abruption with retroplacental clot ✓
- D Vasa previa rupture
Correct answer: C. Severe placental abruption with retroplacental clot
Explanation
Couvelaire uterus describes extravasation of blood into the uterine musculature causing a dark, woody, bruised-appearing uterus; it is pathognomonic of severe placental abruption (abruptio placentae) with large retroplacental hematoma. The extravasated blood dissects between myometrial fibres, leading to uterine atony and DIC. It is not a feature of placenta previa or vasa previa.
