Is it safe to insert an intrauterine contraceptive device (IUCD) during a cesarean section after the baby is delivered in a woman with cerebral venous thrombosis (CVT)?

IUCD Insertion During Cesarean Section in a Patient with Cerebral Venous Thrombosis

Intrauterine contraceptive device (IUCD) insertion during cesarean section is safe and recommended for women with a history of cerebral venous thrombosis (CVT), as it provides effective non-hormonal contraception without increasing thrombotic risk.

Safety of IUCD Insertion During Cesarean Section

General Safety Profile

• Postplacental IUCD insertion during cesarean section has been shown to be safe and effective with high continuation rates and low expulsion rates 1
• A prospective study demonstrated that intracesarean Copper T 380A insertion had:
  • 91% continuation rate at one year
  • Only 5.33% expulsion rate
  • Low complication rates (2% febrile morbidity) 1
• Another study confirmed that women undergoing cesarean section who desire long-term reversible contraception should be offered IUCD insertion during the same procedure 2

Specific Considerations for CVT Patients

Thrombotic Risk Assessment

• Cerebral venous thrombosis is a serious condition with increased risk during pregnancy and postpartum period 3
• The postpartum period, especially after cesarean delivery, represents a high-risk time for CVT development 4
• Cesarean delivery itself is identified as a risk factor for CVT, with onset typically within the first 3 weeks postpartum (mean 9.6 days) 4

Contraceptive Options for Women with CVT

• For women with a history of CVT, non-hormonal contraception is preferred to avoid additional thrombotic risk
• The Copper IUD (Cu-IUD) is classified as Category 1 (no restriction) for women with a history of VTE, making it an ideal choice 5
• Combined hormonal contraceptives (CHCs) would be contraindicated (Category 4) in women with a history of CVT due to increased thrombotic risk 5

Thromboprophylaxis Management

Postpartum Anticoagulation

• Women with a history of VTE (including CVT) should receive postpartum prophylaxis for 6 weeks with prophylactic or intermediate-dose LMWH or vitamin K antagonists 5
• The Society for Maternal-Fetal Medicine recommends that women with previous VTE who undergo cesarean delivery receive both mechanical and pharmacologic prophylaxis for 6 weeks postoperatively 5

Compatibility with IUCD

• There is no contraindication to IUCD insertion in women receiving anticoagulation therapy
• The timing of IUCD insertion during cesarean (immediately after delivery of placenta) avoids the need for a separate procedure while the patient is anticoagulated

Practical Approach

1. Timing of insertion: Insert the IUCD within 10 minutes after delivery of the placenta during cesarean section 5
2. Device selection: Copper T 380A is preferred for women with CVT as it provides non-hormonal contraception
3. Technique: Place the IUCD at the uterine fundus before closure of the uterine incision
4. Anticoagulation management: Continue prescribed thromboprophylaxis as recommended (typically 6 weeks of LMWH) 5
5. Follow-up: Schedule a follow-up visit at 6 weeks postpartum to:
   • Verify IUCD placement
   • Check for visible strings
   • Assess for any complications

Potential Complications and Management

• Bleeding: Minimal risk of increased bleeding with copper IUCD even with anticoagulation
• Infection: Low risk (2%) of postoperative infection 1
• Expulsion: Approximately 5% risk of expulsion within the first year 1
• Perforation: Extremely rare during cesarean insertion due to direct visualization

Common Pitfalls to Avoid

1. Delaying contraception: Waiting for a separate procedure after cesarean increases risk of short interpregnancy interval
2. Using hormonal IUDs: Levonorgestrel IUDs may be less preferable than copper IUDs in women with history of thrombosis
3. Failing to counsel about strings: Inform the patient that strings may not be visible immediately and require checking at follow-up
4. Neglecting thromboprophylaxis: Ensure proper anticoagulation is maintained regardless of IUCD insertion

In conclusion, intracesarean IUCD insertion provides a safe, effective, and convenient contraceptive option for women with a history of cerebral venous thrombosis, while appropriate thromboprophylaxis should be continued as indicated by the patient's risk profile.
