The patient was started on 5000 units of subcutaneous, unfractionated heparin, twice a day, and she was strongly counseled by the MFM to stop smoking.

As there is no argument to prove that low-dose aspirin may have been deleterious, these results support enoxaparin use during such at-risk pregnancies. Please note, we cannot prescribe controlled substances, diet pills, antipsychotics, or other abusable medications.

There have been no randomized controlled trials of treatment for patients known to have FVL.15 It is also unknown whether prophylactic treatment of asymptomatic carriers, such as this patient, improves outcomes, although small observational studies do suggest a benefit.16 Current expert opinion recommends that management be based on the presence of a current VTE, the presence of a past VTE, and risk factors for a VTE during pregnancy.

Arch Gynecol Obstet. This finding has led to a recent meta-analysis showing that factor V Leiden mutation, activated protein C resistance, prothrombin G20210A mutation (factor II G20210A mutation), and protein S deficiency are likely to be associated with a significant risk of fetal loss,3 giving legitimacy to secondary prevention trials using antithrombotic agents, mainly low-molecular-weight heparin (LMWH). The patient was called by her physician and questioned about any family history of NTD, which she denied. Having recurring DVTs or PEs. Patients and physicians were aware of the treatment being taken. Screening should be recommended for women with a personal or family history of VTE, early onset or recurrent preeclampsia, recurrent IUGR, unexplained IUFD, and unexplained placental abruption.1 Ideally, testing should be done remote from any thrombotic event, when the patient is not pregnant and not on any anticoagulation, because heparin may interfere with the assays.

This content does not have an English version. A recent study showed that exposure to aspirin during pregnancy increases miscarriages.21 The risk was however limited to the prenatal use of aspirin and treatments. The American College of Obstetricians and Gynecologists recommends prophylactic doses of heparin during and after the pregnancy for women who are heterozygous for FVL and also have a history of one previous VTE.17 If these patients are currently taking long-term anticoagulation for a previous VTE, they should receive full anticoagulation with heparin as previously discussed.12 Women who are heterozygous for FVL and also have a history of a previous pregnancy complication, such as preeclampsia, IUFD, IUGR, or placental abruption, are also candidates for heparin prophylaxis.

I definitely agree with you when it comes to erring on the side of caution! deep vein thrombosis during pregnancy (8-fold increased Neonates' weights were not, for each of the treatments, correlated to the intensity of tobacco consumption before pregnancy nor to the residual tobacco consumption during pregnancy.
