Even if complete CUS is safe to rule out DVT in pregnant women, current diagnostic strategies for suspected DVT in non-pregnant patients rely on the use of clinical probability and D-Dimer prior to leg veins imaging [5]. However, no management outcome study on the safety and usefulness of D-Dimer to rule out DVT in pregnant women is available to date. Another limitation of the strategies based on a single unique complete CUS, is that every woman has to undergo complete CUS. However, this test is not always available. Therefore, a strategy in which the association of clinical probability assessment and D-dimer measurement would allow to safely rule out DVT in a significant proportion of patients without performing a complete CUS, would be of great help in everyday clinical practice and would probably be cost-effective.
