Deep vein thrombosis (DVT) is the formation of a blood clot in a deep vein, most commonly in the legs or pelvis. The rationale for performing a leg ultrasound in a pregnant woman with suspected DVT is that if DVT is confirmed, this leads to the same therapy as PE, and consequently chest imaging can be avoided altogether. Hellenic J Cardiol. Venous stasis occurs when blood flow is decreased, as in immobility, medication therapies and in heart failure.Hypercoagulability occurs most commonly in clients with deficient fluid volume, pregnancy, oral contraceptive use, smoking, and some blood dyscrasias.Venous wall damage may occur secondary to venipuncture, certain medications, trauma, and surgery. 2019 Jul 4;20(1):944. doi: 10.4102/sajhivmed.v20i1.944.

Initial anticoagulant treatment of VTE in pregnancy What is the initial treatment of VTE in pregnancy? Diagnosis of deep vein thrombosis (DVT) in pregnant women can be difficult given that the Wells’score and D-dimer are not validated for use, Compression ultrasonography with Doppler examination of the iliofemoral region is the first line diagnostic tool, Anticoagulation with low molecular weight heparin is the preferred treatment for pregnant women with DVT, but optimal duration and dosing schedule remain unclear, Women with DVT related to pregnancy are at higher risk of embolic complications and of post-thrombotic syndrome than non-pregnant women, Management of DVT around labour and delivery involves balancing the risk of bleeding from anticoagulation with the risk of clot recurrence and the need for regional anaesthesia.
