Extra scan may catch more postpartum blood clots
NCT ID NCT02616991
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looked at whether adding a CT venography scan (imaging of the pelvis and legs) to the standard chest CT can find more blood clots in women who recently gave birth and are suspected of having a pulmonary embolism. 125 women participated. The goal was to see if the combined approach detects more venous thromboembolism than chest CT alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could improve detection of blood clots in new mothers, leading to faster treatment and fewer complications.
- What could go wrong
- This is a small, completed study focused on diagnosis, not treatment. The added scan increases radiation exposure, and the benefit may not be large enough to change standard practice.
