A 28 year old woman comes to you with the repo of a USG done at 13 weeks, it shows the child has anencephaly and as a result of which she would like to do an MTP. Which of the following is NOT a preferred method of MTP in this condition?
Anencephaly is a severe neural tube defect where the brain and skull don't develop properly. It's incompatible with life, so termination is often considered. In many countries, the legal limit for termination is around 20 weeks, but the method depends on gestational age.
At 13 weeks, the options are either medical or surgical. Medical termination usually involves mifepristone and misoprostol, which are effective up to 14 weeks. Surgical methods include vacuum aspiration (up to 14 weeks) and dilation and evacuation (D&E) for later weeks. However, D&E is typically used beyond 14 weeks because the cervix is more dilated and the fetus is larger.
If the options include D&E as an option, then that might be the incorrect answer here because it's not preferred at 13 weeks. The preferred methods would be vacuum aspiration or medical management. So the incorrect method would be D&E since it's used later. Let me check the options again. The user didn't list them, but assuming the options include D&E as one of the choices, that would be the answer.
Wait, but some sources might consider D&E as a method even before 14 weeks in certain cases. However, the standard is that vacuum aspiration is preferred up to 14 weeks. So if the wrong option is D&E, then that's the one not preferred. I need to make sure there's no other method that's not preferred. Also, maybe a method like induction with prostaglandins, which is used later, but at 13 weeks, that's not standard. But the question is about the NOT preferred method. So the answer is D&E because it's used after 14 weeks.
**Core Concept**
Anencephaly is a lethal neural tube defect incompatible with life. Termination of pregnancy (MTP) at 13 weeks requires methods suitable for early gestation. Preferred techniques include vacuum aspiration or medical termination with mifepristone/misoprostol. Dilation and evacuation (D&E) is typically reserved for later gestation due to anatomical challenges.
**Why the Correct Answer is Right**
Dilation and evacuation (D&E) is **not preferred** at 13 weeks because the cervix is not sufficiently dilated or effaced, and the fetal size is too small for efficient tissue removal. Vacuum aspiration (up to 14 weeks) or medical termination (mifepristone/misoprostol) are safer, less invasive, and more effective at this gestational age. D&E is associated with higher risks of cervical trauma and incomplete evacuation in early pregnancy.
**Why Each Wrong Option is Incorrect**
**Option A:** Vacuum aspiration is preferred up to 14 weeks due to its safety and efficacy.
**Option B:** Medical termination with mifepristone/misoprostol is first-line for early pregnancy termination (up to 14 weeks).
**Option C:** Dilation and curettage (D&C) is outdated and replaced
