It is not necessary to follow the activated partial thromboplastin time.10 Anti-Xa levels need only be obtained in patients who are at extremes of weight (< 121 lb [55 kg] or > 198 lb [90 kg]) or have abnormal renal function.12 Monitoring of platelets while on LMWH is no longer recommended.12 UFH may be used instead of LMWH for the treatment of VTE in pregnancy, because of cost or availability. UFH is considered an acceptable alternative.32 Table 1 recommends dosages and monitoring.10,12,32,41 For postpartum DVT or PE, warfarin may be started concomitantly with heparin.42 LMWH or UFH should be continued until an international normalized ratio of 2.0 to 3.0 is achieved for two consecutive days.42 Post-thrombotic syndrome can be prevented if compression stockings are worn for at least one year starting in the first month after a DVT.1, Intrapartum management may vary depending on the indication for anticoagulation and whether therapeutic or prophylactic doses have been used.10 Expert guidelines suggest that women receiving adjusted-dose LMWH or UFH be instructed to discontinue heparin injections at the onset of labor to prevent anticoagulant complications during delivery.12,32 When delivery is predictable, as for elective induction or planned cesarean birth, LMWH or UFH should be discontinued 24 hours before delivery.12,32 For high-risk patients, such as those with mechanical heart valves or recent VTE, the American College of Obstetricians and Gynecologists (ACOG) recommends switching to intravenous heparin at the onset of labor.10 The short half-life of intravenous UFH allows discontinuation four to six hours before the anticipated time of delivery.10,32 To minimize spinal and epidural hematoma risk, the ACOG and the American Society of Regional Anesthesia advise avoiding regional anesthesia for 24 hours after the last LMWH dose for women on twice daily therapeutic doses of enoxaparin (Lovenox), and for 12 hours after the last dose of LMWH for women receiving daily prophylactic dosing.10, Evidence is insufficient to recommend for or against an inferior vena cava filter if anticoagulation is contraindicated or repeat PE occurs despite adequate anticoagulation.1, Systematic reviews of observational studies have found VTE prophylaxis with LMWH to be safe and effective in pregnancy, but there are no randomized controlled trials confirming this.35,42 Table 2 lists representative prophylactic doses of LMWH and subcutaneous UFH.6,43 Table 3 summarizes recommendations for the type and duration of prophylaxis based on specific clinical risk factors.5,10,15,32,39,40 Consultation should be considered for high-risk thrombophilias such as antithrombin deficiency.6, Low-dose aspirin (75 to 81 mg) is sometimes used for women with an increased risk of thrombosis that does not meet the threshold for prophylactic heparin (e.g., a woman with a mild thrombophilia and no history of VTE).6 Due to the lack of studies of aspirin for this indication, such treatment is of unknown benefit; however, low-dose aspirin is safe to use during pregnancy.32, Postpartum thromboprophylaxis is not routinely indicated following vaginal delivery,42 but may become necessary because of labor-related risk factors, such as prolonged labor, mid-forceps delivery, and immobility after delivery.6, Unless other VTE risk factors are also present, women who undergo a scheduled cesarean delivery are not routinely placed on pharmacologic VTE prophylaxis.44 However, mechanical prophylaxis with pneumatic compression stockings has been shown to provide effective post-cesarean thromboprophylaxis.45 Graduated compression stockings provide effective prophylaxis in nonpregnant postoperative patients.46 A decision analysis comparing pneumatic compression stockings with no intervention for post-cesarean VTE prophylaxis found the former to be cost-effective.47. National Library of Medicine Interested in Group Sales? 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.

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.
