Abstract Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), is a leading cause of maternal mortality during pregnancy. DVT and PE are commonly suspected due to many mimicking signs and symptoms that are normal in pregnancy. However, validated diagnostic approaches are lacking, and a fear of teratogenic/oncogenic exposure from imaging procedures affects the acceptability of diagnostic approaches used for VTE during pregnancy. DVT and PE treatment in pregnancy is also challenging due to this lack of validated diagnostic approaches, changes in maternal physiology, and the need for intact hemostasis at the time of delivery/epidural analgesia. Prevention requires an optimal balancing of absolute increased bleeding risk from pharmacologic thromboprophylaxis and the absolute benefit of reduced DVT and PE, which, while serious, are relatively uncommon.
