What is the most common reason for late postpartum hemorrhage (PPH)?

  • A. Subinvolution of the uterus
  • B. Defective vascularity of the decidua
  • C. Cervical lacerations
  • D. Coagulation disorders
Correct Answer: A

Rationale: Late postpartum hemorrhage (PPH), defined as occurring between 24 hours and up to 12 weeks after delivery, is most commonly due to subinvolution of the uterus. This occurs when the uterus fails to return to its normal pre-pregnancy size. Subinvolution can be caused by retained products of conception, uterine infection, uterine anomalies, or inadequate contraction of the uterine muscles. When the uterus does not contract effectively, it is unable to compress the blood vessels at the site of the placental attachment, leading to persistent bleeding. Subinvolution of the uterus is an important cause of late PPH and requires prompt intervention to prevent excessive blood loss and its associated complications.
