Following are contraindication to External Cephalic Version except :
**Core Concept**
External Cephalic Version (ECV) is a procedure used to manually rotate a fetus from a breech presentation to a cephalic presentation, typically between 37 and 39 weeks of gestation. The procedure is contraindicated in certain situations to prevent complications and ensure the safety of both the mother and the fetus.
**Why the Correct Answer is Right**
The correct answer to the question will highlight a situation where ECV is not contraindicated. One such scenario is a previous successful ECV, which indicates that the mother is a good candidate for the procedure and has a lower risk of complications. This is because the mother has demonstrated the ability to safely undergo the procedure in the past, and her body has shown a favorable response to the rotation.
**Why Each Wrong Option is Incorrect**
* **Option A:** Previous unsuccessful ECV is a contraindication because it may indicate that the mother's body is not suitable for the procedure, and attempting it again may increase the risk of complications.
* **Option B:** Multiple gestations (twins or more) are a contraindication because the procedure can be challenging and may lead to complications in both the mother and the fetuses.
* **Option C:** Placenta previa is a contraindication because the procedure may cause bleeding, which can be life-threatening for both the mother and the fetus.
**Clinical Pearl / High-Yield Fact**
A previous successful ECV is a strong predictor of a successful subsequent ECV, and it is essential to take a thorough history to determine if the mother has had any previous attempts at ECV.
**Correct Answer: D. Previous successful ECV is not a contraindication to External Cephalic Version.**
