Pregnancy-Related DVT Could Be Eliminated With Single Scan

Research: Single complete compression ultrasonography’s diagnostic value in pregnant and postpartum women with assumed deep vein thrombosis: potential study. Compression ultrasonography, a single ultrasound scan, may safely rule out a diagnosis of deep vein thrombosis (DVT) in women during pregnancy or in the initial weeks after birthing i.e. post-partum period, discovers study published on bmj.com.

During pregnancy the risk of DVT increases, but accurately diagnosing it is a challenge for doctors. Tests that are safe and reliable in non-pregnant patients are not always appropriate to use during pregnancy.

So a team of researchers, led by Professor Grégoire Le Gal from the University of Brest in France, set out to assess the safety of a single complete compression ultrasonography in pregnant and post-partum women with suspected DVT.

The study included 210 pregnant and post-partum women referred for suspected DVT from medical practices in France and Switzerland.

A single compression ultrasound scan was performed on each patient and anti-clotting treatment was given to those with a positive result. All women were followed up for three months.

Deep vein thrombosis was diagnosed in 22 (10.5%) of the 210 women. Of the 177 patients without deep vein thrombosis and who did not receive anti-clotting treatment, two patients (1.1%) experienced a confirmed DVT during follow-up.

Study limitations prevent the authors from drawing firm conclusions. Nevertheless, they suggest that a single complete compression ultrasonography "might be safe for ruling out deep vein thrombosis in pregnant and post-partum women." They add that further studies are needed to confirm their findings.
