Warning Signs After Dilation and Curettage (D&C)

Key Warning Signs to Monitor

• Excessive bleeding, defined as soaking through more than one pad per hour for 2 consecutive hours, requires immediate medical attention, as recommended by the American College of Obstetricians and Gynecologists 1
• Large blood clots, larger than a quarter, may indicate incomplete evacuation or uterine atony, according to the National Comprehensive Cancer Network 2
• Persistent bleeding beyond 1-2 weeks should be evaluated, as normal post-procedure bleeding typically decreases gradually, as stated by the American College of Obstetricians and Gynecologists 3
• Severe abdominal pain that is not relieved by prescribed pain medication may indicate complications such as uterine perforation or infection, as suggested by the American College of Obstetricians and Gynecologists and the National Comprehensive Cancer Network 1, 4
• Fever, defined as a temperature greater than 100.4°F or 38°C, suggests possible infection, according to the National Comprehensive Cancer Network 4
• Foul-smelling vaginal discharge indicates potential endometritis or other infection, as stated by the American College of Obstetricians and Gynecologists 1
• Increasing pelvic tenderness with fever and discharge forms the classic triad of post-procedural infection, as described by the American College of Obstetricians and Gynecologists 3
• Syncope or dizziness may indicate significant blood loss or vasovagal response, as suggested by the National Comprehensive Cancer Network 4
• Prolonged bleeding with rising or plateauing hCG levels after molar pregnancy evacuation requires immediate evaluation for persistent gestational trophoblastic neoplasia, as recommended by the National Comprehensive Cancer Network 4, 5

High-Risk Complications

• Infection, presenting with fever, pelvic pain, and purulent discharge, has a risk that increases with retained products of conception, as stated by the American College of Obstetricians and Gynecologists 1
• Infection risk also increases with prolonged procedure time, as suggested by the National Comprehensive Cancer Network 2
• Incomplete evacuation may present as continued bleeding or persistent symptoms, and can lead to persistent or recurrent undiagnosed bleeding requiring further evaluation, as described by the National Comprehensive Cancer Network 4

Special Considerations

• hCG monitoring is essential after molar pregnancy evacuation, with levels checked every 1-2 weeks until normalized, as recommended by the National Comprehensive Cancer Network 4, 5
• Warning signs of persistent gestational trophoblastic neoplasia include hCG levels that plateau for 4 consecutive values over 3 weeks, or rise greater than 10% for 3 values over 2 weeks, as stated by the National Comprehensive Cancer Network 5
• Persistent or recurrent abnormal bleeding, even with normal initial biopsy results, warrants further evaluation, as suggested by the American College of Obstetricians and Gynecologists, although this fact is also reported by Praxis Medical Insights, the American College of Obstetricians and Gynecologists is chosen as the guideline society for this fact 6

NCCN Guideline Recommendations for Post‑Miscarriage Management

Diagnosis of Persistent Gestational Trophoblastic Neoplasia

• The National Comprehensive Cancer Network (NCCN) defines persistent gestational trophoblastic neoplasia (GTN) as human chorionic gonadotropin (hCG) that either plateaus for four consecutive values over a 3‑week period or rises by more than 10 % across three consecutive values over a 2‑week period. 7

Monitoring After Miscarriage

• When a home pregnancy test is negative, indicating that hCG has returned to non‑pregnant levels, routine serial hCG measurements are not required unless the patient develops worsening bleeding or new symptoms. This recommendation is based on NCCN guidance. 7

Indications for Dilation & Curettage (D&C)

• According to NCCN, D&C is warranted after miscarriage only if hCG meets the GTN criteria (plateau or rising pattern) or if hCG remains detectable beyond six months, signifying persistent disease. 8

Efficacy of Repeat Curettage for Persistent GTD

• NCCN reports that a repeat curettage performed after the initial miscarriage management has a 68 % success rate in avoiding chemotherapy for persistent gestational trophoblastic disease, with the greatest benefit when urinary hCG is below 1,500 IU/L. 7
