Lazo-Langner A, et al. - Researchers attempted to explore the optimal prophylactic strategies in pregnant women with a history of venous thromboembolism (VTE). Subjects were followed until 6 weeks postpartum. Patients with a previous unprovoked event (including antepartum VTE) received antenatal prophylaxis, mostly with low dose low molecular weight heparin (LMWH). Among 199 pregnancies, 147 pregnancies occurred in women with unprovoked or estrogen-related VTE history and 52 pregnancies in women with provoked VTE. Data displayed the low occurrence of ante- and postpartum VTE recurrences in patients with previous VTE due to the use of prophylactic doses of LMWH during pregnancy and puerperium.
