Area of Science:

  • Obstetrics and Gynecology
  • Pharmacology
  • Hematology

Background:

  • Anticoagulant therapy during pregnancy poses significant risks.
  • Vitamin K antagonists (VKAs) are associated with teratogenicity.
  • Heparins offer an alternative but require careful management.

Purpose of the Study:

  • To review the challenges of anticoagulant use in pregnancy.
  • To outline considerations for unfractionated heparin (UFH) and low molecular weight heparin (LMWH).
  • To provide therapeutic recommendations for various obstetric scenarios.

Main Methods:

  • Comprehensive literature review.
  • Analysis of existing guidelines and clinical data.
  • Synthesis of evidence for therapeutic recommendations.

Main Results:

  • VKAs carry risks of embryopathy and fetal hemorrhage.
  • UFH and LMWH have different pharmacokinetic profiles and risks during pregnancy.
  • Established recommendations for VTE treatment/prophylaxis, mechanical heart valves, and antiphospholipid syndrome.

Conclusions:

  • Careful selection and monitoring of anticoagulants are crucial in pregnancy.
  • Heparins are generally preferred over VKAs in most pregnant patients.
  • Tailored management strategies are essential for optimizing outcomes.
