In addition, women treated with UFH usually require monitoring of platelet counts during the first two to three weeks of therapy because of the small potential for heparin-induced thrombocytopenia (HIT), but the risk of HIT with LMWH is lower.

PMC This is consistent with recommendations from the Society of Obstetric Anesthesia and Perinatology (SOAP) consensus statement on the Anesthetic Management of Pregnant Women Receiving Thromboprophylaxis3 and the 2018 American Society of Hematology (ASH) 2018 guidelines for management of venous thromboembolism in the context of pregnancy5. 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.

Venous compression ultrasonography is the test of choice for diagnosing DVT because it is noninvasive, safe, and relatively inexpensive.12,20 In nonpregnant patients, it is 89 to 96 percent sensitive and 94 to 99 percent specific for symptomatic proximal lower extremity DVT.19 Sensitivity is lower in patients who are asymptomatic or have a calf DVT.19 In nonpregnant patients, computed tomography and magnetic resonance imaging have equivalent or better sensitivities and specificities than ultrasonography for DVT detection.23 Data are lacking for pregnant patients.

Some authorities recommend lower extremity venous compression ultrasonography as the next test because if DVT is present, anticoagulant treatment will be the same as for PE, and venous compression ultrasonography avoids fetal radiation exposure.12,28, When d-dimer testing and venous compression ultrasonography are inconclusive, multidetector-row (spiral) computed tomography has become the test of choice for diagnosing PE in pregnancy.12,24,26 Single-slice computed tomography is inadequate in diagnosing peripheral PE, but newer-generation spiral computed tomography, tested in nonpregnant patients, has shown positive and negative predictive values comparable with pulmonary angiography.27 Fetal exposure to radiation is lower with spiral computed tomography than with ventilation-perfusion (V/Q) scanning (less than 130 Gy and 370 Gy, respectively), and fetal exposure to spiral computed tomography nonionic contrast appears safe.29 Spiral computed tomography does expose the maternal breast to greater radiation, and V/Q scanning may be preferred in women with a family history of breast cancer.12 A cost-benefit analysis supports spiral computed tomography as the preferred test for diagnosing PE during pregnancy.30.
