Ultrasound plus Doppler can rule out deep vein thrombosis in pregnant women

The use of compression ultrasonography with Doppler imaging of the iliac vein can be used to rule out deep vein thrombosis in symptomatic pregnant women, according to a study published in the Canadian Medical Association Journal, MedPage Today reports.

Of the 205 women studied using a combination of serial compression ultrasound and Doppler imaging, just one had a venous thromboembolic event, a pulmonary embolism, in follow-up. With a sensitivity of 94.1 percent and a negative predictive value of 99.5 percent, according to Wee-Shian Chan, M.D., of B.C. Women's Hospital & Health Center in Vancouver, "it is likely safe to withhold anticoagulation in women with negative imaging results." Article
