The intial diagnostic test in a pregnant woman suspected to have a<unk><unk>  (PE) depends on the presence or absence of leg symptoms suggestive of deep vein thrombosis (DVT).  Compression ultrasonography is not the routine initial method of evaluation in a suspected PE during pregnancy unless the patient has coexisting symptoms and signs of DVT.  In case the compression ultrasound is negative for DVT and there is persistent clinical suspicion of PE, the negative ultrasound does not rule out PE and additional imaging tests are required.  If leg symptoms are absent in a pregnant woman suspected to have PE, a chest X-ray is the initial imaging modality.  When anticoagulation is indicated for the prevention or treatment of venous thromboembolism in pregnancy, low molecular weight heparin (LMWH) should be administered instead of vitamin K antagonists (VKA).  In fact, VKA can cross the placenta and lead to embryopathy as well as fetal loss.  Some of the teratogenic effect of VKA include midfacial hypoplasia, stippled epiphysis, and limb hypoplasia.  The teratogenic effect of VKA is particularly important during the first trimester of pregnancy.
