Despite the administration of prophylactic and therapeutic heparin to pregnant women with a current or past history of venous thromboembolism (VTE), VTE remains a major cause of maternal morbidity and mortality.1 Although low molecular-weight-heparin (LMWH) has replaced the use of unfractionated heparin (UFH) during pregnancy to a great extent (because of its lower complication rate, predictable dosing, ease of administration, and greater reduction in thrombus size compared to UFH), a common practice is to switch pregnant women treated with LMWH to UFH approximately three to four weeks prior to the expected date of delivery (around 36 weeks of gestation for a planned term delivery), and continue UFH until after delivery.2 This practice stems from the easy reversibility and short half-life of UFH and the need to balance efficient anticoagulation during pregnancy with the womans desire for neuraxial analgesia in the event of spontaneous labor within 12 to 24 hours of administration of LMWH.
