Some authorities recommend lower extremity venous compression ultrasonography as the next test because if DVT is present, anticoagulant treatment will be the same as for PE, and venous compression ultrasonography avoids fetal radiation exposure.12,28, When d-dimer testing and venous compression ultrasonography are inconclusive, multidetector-row (spiral) computed tomography has become the test of choice for diagnosing PE in pregnancy.12,24,26 Single-slice computed tomography is inadequate in diagnosing peripheral PE, but newer-generation spiral computed tomography, tested in nonpregnant patients, has shown positive and negative predictive values comparable with pulmonary angiography.27 Fetal exposure to radiation is lower with spiral computed tomography than with ventilation-perfusion (V/Q) scanning (less than 130 Gy and 370 Gy, respectively), and fetal exposure to spiral computed tomography nonionic contrast appears safe.29 Spiral computed tomography does expose the maternal breast to greater radiation, and V/Q scanning may be preferred in women with a family history of breast cancer.12 A cost-benefit analysis supports spiral computed tomography as the preferred test for diagnosing PE during pregnancy.30. American College of Obstetricians and Gynecologists. Based on data from nonpregnant patients, PE can be excluded with a normal or low probability V/Q scan if clinical suspicion is low to moderate.25 Likewise, PE can be diagnosed with a high probability scan if clinical suspicion is moderate to high.25 In a study of V/Q scanning in 120 pregnant women with suspected PE, 73.5 percent were normal and 1.8 percent were high probability, compared with 27 to 36 percent normal and 8 to 14 percent high probability scans in nonpregnant patients.31 When V/Q scanning is nondiagnostic, additional options include repeat leg compression ultra-sonography, repeat V/Q scanning, spiral computed tomography, magnetic resonance imaging, and pulmonary angiography.

National Library of Medicine The https:// ensures that you are connecting to the Venous thromboembolism (VTE), which encompasses deep venous thrombosis (DVT) and pulmonary embolism (PE), complicates 0.5 to 3.0 per 1,000 pregnancies,1 and is the leading cause of maternal mortality in the United States.2 A 2007 American College of Physicians and American Academy of Family Physicians practice guideline,1 based on a systematic review,3 found only 11 high quality studies relating to the management of VTE in pregnancy, and concluded that there is inadequate evidence for definitive recommendations.1, Virchow's triad of hypercoagulation, vascular damage, and venous stasis all occur in pregnancy, resulting in a relative risk of 4.3 (95% confidence interval [CI], 3.5 to 5.2) for VTE in pregnant or postpartum women compared with nonpregnant women.4, VTE risk factors include age greater than 35 years, obesity (body mass index higher than 30 kg per2), grand multiparity, and a personal or family history of VTE or thrombophilia.5,6 Bed rest, immobility for four days or longer, hyperemesis, dehydration, medical problems (e.g., severe infection, congestive heart failure, nephrotic syndrome), preeclampsia, severe varicose veins, surgery, and trauma are also associated with an increased risk.6,7 Cesarean delivery significantly increases VTE risk compared with vaginal delivery (odds ratio [OR] = 13.3; 95% CI, 3.4 to 51.4).8, Approximately 50 percent of pregnant women with VTE have a thrombophilia, compared with 10 percent of the general population.5 Current evidence does not support universal thrombophilia screening.9 However, expert opinion suggests testing women with a personal or strong family history of thrombosis or thrombophilia.10 During pregnancy, results must be interpreted with caution, because protein S levels normally fall in the second trimester.11 Massive thrombus and nephrotic syndrome can decrease antithrombin levels, and liver disease decreases protein C and S levels.12, Thrombophilic disorders may be inherited or acquired.13,14 Factor V Leiden and prothrombin G20210A mutations are the most common.13 Antiphospholipid antibody syndrome, the most important acquired thrombophilia in pregnancy, is defined by the presence of antiphospholipid antibodies and one or more clinical manifestations, most commonly thrombosis or recurrent miscarriage.15 A positive test for lupus anticoagulant, or medium-to-high titers of anticardiolipin immunoglobulin G or M antibodies, provides adequate laboratory confirmation of antiphospholipid antibody syndrome if found twice at least six weeks apart.15, Thrombophilias are associated with pregnancy complications, including early and late pregnancy loss, intra-uterine growth restriction, and placental abruption.9, DVT occurs with equal frequency in each trimester and postpartum.16 During pregnancy, 78 to 90 percent of DVTs occur in the left leg5,7 and 72 percent in the ilio-femoral vein, where they are more likely to embolize.5 In nonpregnant patients, 55 percent are in the left leg and 9 percent in the iliofemoral vein.5.

Get weekly updates on baby and your body. Venography still serves as the definitive test for diagnosing DVT19 and may be used in clinical situations where noninvasive tests are equivocal, empiric anticoagulation is relatively contraindicated, and clinical suspicion is high.24, Figure 2 outlines a diagnostic approach for suspected PE based on expert opinion derived from studies mostly involving nonpregnant patients.2427, With low or moderate clinical suspicion, a negative highly sensitive d-dimer test rules out PE.25,28 If d-dimer testing is positive, or if clinical suspicion is high, additional testing is needed.
