Which of these is a delayed complication of massive bleeding secondary to placenta pre?
The options aren't given, but the correct answer is supposed to be something that happens later. Common delayed complications after significant blood loss could include things like hypovolemic shock initially, but that's acute. Then, looking at longer-term issues, maybe something like Sheehan's syndrome? Wait, Sheehan's is due to pituitary infarction from postpartum hemorrhage. That's a delayed complication because the pituitary can't handle the stress of labor and delivery, leading to necrosis. So if there's massive bleeding, especially in the postpartum period, the pituitary gland, which is already hyperemic during pregnancy, might infarct. That would cause hypopituitarism symptoms later.
Other possibilities might be infertility, but Sheehan's is more specific. Let me check: placenta previa itself isn't directly causing Sheehan's, but the massive bleeding from it could lead to it. So the delayed complication would be Sheehan's syndrome. The other options might include acute issues like hemorrhagic shock, DIC, or acute renal failure, which are immediate. So the delayed one would be Sheehan's. I need to make sure that Sheehan's is indeed a delayed complication of postpartum hemorrhage, which it is. So the correct answer here would be Sheehan's syndrome.
**Core Concept**
Placenta previa is an obstetric condition where the placenta implants over the cervix, causing painless vaginal bleeding. Massive postpartum hemorrhage from placenta previa can lead to **Sheehan's syndrome**, a delayed complication due to pituitary infarction secondary to hypovolemic shock.
**Why the Correct Answer is Right**
Sheehan's syndrome occurs when severe postpartum hemorrhage leads to ischemic necrosis of the pituitary gland. The pituitary becomes hyperemic during pregnancy, making it vulnerable to hypoperfusion during acute blood loss. Delayed symptoms include amenorrhea, galactorrhea, fatigue, and adrenal insufficiency due to loss of pituitary hormone production.
**Why Each Wrong Option is Incorrect**
**Option A:** Hemorrhagic shock is an *acute* complication, not delayed.
**Option B:** Disseminated intravascular coagulation (DIC) occurs during the acute phase of bleeding.
**Option C:** Acute renal failure is a direct consequence of hypovolemia, not a delayed effect.
**Clinical Pearl / High-Yield Fact**
Sheehan’s syndrome is a classic "postpartum pituitary apoplexy" – remember the **"MOMA"** mnemonic: **M**assive postpartum **H**emorrhage → **O**ccult pituitary **I**nfarction → **A**nterior pituitary failure. Always consider hormonal evaluation in postpartum women with unexplained fatigue or
