According to this study: In women who have a history of venous thromboembolism, weight-adjusted intermediate-dose low-molecular-weight heparin during the combined antepartum and postpartum periods didn't reduce the risk of recurrence compared with fixed low-dose low-molecular-weight heparin.Further study is needed to determine whether intermediate-dose low-molecular-weight heparin may be more . Closed management is needed during the peripartum period, and discontinuing Low-molecular-weight heparins at least 12 h before delivery seems sufficient to prevent post-partum haemorrhage. 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.
