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. 2004; 29(3):186-92 (ISSN: 0361-929X).  |  Epub 2010 Mar 3. 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. NLM Additional risk factors are preeclampsia, Cesarean section, instrument-assisted delivery, hemorrhage, multiparity, varicose veins, a previous history of a thromboembolic event, and hereditary or acquired thrombophilias such as Factor V Leiden.

Int J Endocrinol. The overlap with symptoms of pregnancy may impair clinical suspicion making diagnosis of VTE more challenging. Deep vein thrombosis (DVT) is the formation of a blood clot within the deep veins, most commonly those of the lower extremities.The main risk factors for DVT are vascular endothelial damage (e.g., surgery or trauma), venous stasis (e.g., immobility), and hypercoagulability (e.g., thrombophilia), collectively referred to as the Virchow triad. DVT results from conditions that impair venous return, lead to endothelial injury or dysfunction, or cause hypercoagulability. 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. 3–5 VTE risk is increased due to physiologic and anatomic changes that occur in pregnancy.
