The use of heparin during pregnancy has been prevalent for quite some time. During pregnancy and the immediate period after birth, the risk of venous thrombosis is increased. Heparin does not cross the placenta, and thus, it was surprising that a recent report concluded that heparin therapy during pregnancy was as risky as oral anticoagulant therapy. It crosses the placenta and increases the risk of miscarriage, stillbirth, embryopathy (nasal hypoplasia or stippled epiphyses), central nervous system abnormalities, and maternal and fetal hemorrhage.32 Warfarin is compatible with breastfeeding.32, Data derived from nonpregnant populations suggest that therapeutic anticoagulation following a first episode of VTE should continue for at least six months from diagnosis.38 Current recommendations for the duration of treatment in pregnancy range from three to six months, including six weeks postpartum.10,12,32 Long-term (i.e., longer than 12 months) anticoagulation is indicated for women with VTE and antiphospholipid antibody syndrome, or two or more thrombophilias,39 and for women with any thrombophilia and recurrent thrombotic events.40. The National Blood Clot Alliance (NBCA), a leading VTE advocacy group in North America, was funded through a five-year cooperative agreement to help address the lack of education on blood clots for the public. Venous thromboembolism (VTE), which encompasses deep venous thrombosis (DVT) and pulmonary embolism (PE), complicates 0.5 to 3.0 per 1,000 pregnancies,1 and is the leading cause of maternal mortality in the United States.2 A 2007 American College of Physicians and American Academy of Family Physicians practice guideline,1 based on a systematic review,3 found only 11 high quality studies relating to the management of VTE in pregnancy, and concluded that there is inadequate evidence for definitive recommendations.1, Virchow's triad of hypercoagulation, vascular damage, and venous stasis all occur in pregnancy, resulting in a relative risk of 4.3 (95% confidence interval [CI], 3.5 to 5.2) for VTE in pregnant or postpartum women compared with nonpregnant women.4, VTE risk factors include age greater than 35 years, obesity (body mass index higher than 30 kg per2), grand multiparity, and a personal or family history of VTE or thrombophilia.5,6 Bed rest, immobility for four days or longer, hyperemesis, dehydration, medical problems (e.g., severe infection, congestive heart failure, nephrotic syndrome), preeclampsia, severe varicose veins, surgery, and trauma are also associated with an increased risk.6,7 Cesarean delivery significantly increases VTE risk compared with vaginal delivery (odds ratio [OR] = 13.3; 95% CI, 3.4 to 51.4).8, Approximately 50 percent of pregnant women with VTE have a thrombophilia, compared with 10 percent of the general population.5 Current evidence does not support universal thrombophilia screening.9 However, expert opinion suggests testing women with a personal or strong family history of thrombosis or thrombophilia.10 During pregnancy, results must be interpreted with caution, because protein S levels normally fall in the second trimester.11 Massive thrombus and nephrotic syndrome can decrease antithrombin levels, and liver disease decreases protein C and S levels.12, Thrombophilic disorders may be inherited or acquired.13,14 Factor V Leiden and prothrombin G20210A mutations are the most common.13 Antiphospholipid antibody syndrome, the most important acquired thrombophilia in pregnancy, is defined by the presence of antiphospholipid antibodies and one or more clinical manifestations, most commonly thrombosis or recurrent miscarriage.15 A positive test for lupus anticoagulant, or medium-to-high titers of anticardiolipin immunoglobulin G or M antibodies, provides adequate laboratory confirmation of antiphospholipid antibody syndrome if found twice at least six weeks apart.15, Thrombophilias are associated with pregnancy complications, including early and late pregnancy loss, intra-uterine growth restriction, and placental abruption.9, DVT occurs with equal frequency in each trimester and postpartum.16 During pregnancy, 78 to 90 percent of DVTs occur in the left leg5,7 and 72 percent in the ilio-femoral vein, where they are more likely to embolize.5 In nonpregnant patients, 55 percent are in the left leg and 9 percent in the iliofemoral vein.5. Heres why: Several other factors may also increase a pregnant womans risk for a blood clot: Too many women die from pregnancy-related complications and many more experience severe-pregnancy-related complications. zo90q |%()J 69#YVWpC(H#Vg
