A woman presents with missed abortion at 9 weeks. Her cervix is closed and uterus corresponds to 9 weeks. What is the definition of expectant management 'success' in missed abortion, and within what period is it expected?

• A Complete expulsion of POC within 2 weeks in approximately 80% of cases
• B Reduction in hCG to undetectable within 1 week
• C Complete expulsion of POC confirmed by ultrasound within 2 weeks in approximately 50% of cases ✓
• D Complete expulsion of POC within 6 weeks in 30% of cases

Explanation

For missed abortion managed expectantly, complete expulsion occurs in approximately 50% of women within 2 weeks and up to 80–85% within 4–6 weeks. This contrasts with medical management (misoprostol), which achieves complete expulsion in approximately 80–85% within 2 weeks. Surgical management (ERPC/MVA) has the highest success rate (>95%) but carries procedural risks. Patient preference, clinical stability, and gestational age guide the choice between these three approaches.
