Prevention of VTE in women with prior VTE or thrombophilia. Guideline recommendations around VTE and thrombophilia can be broadly summarized as follows: Antepartum + postpartum thromboprophylaxis is recommended for women with prior unprovoked VTE or VTE provoked by estrogen or pregnancy (A) and for some strong thrombophilias, particularly if associated with a family history of VTE (B) due to a higher predicted recurrence risk than for women with a VTE provoked by major transient nonhormonal provoking factors and some weaker thrombophilias, for whom only postnatal thromboprophylaxis is recommended (C).
