Safer scans: ultrasound may replace CT for aortic aneurysm monitoring
NCT ID NCT04196543
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a special ultrasound with contrast dye can be as good as CT scans for checking aortic endoprostheses after abdominal aortic aneurysm repair. Forty patients received both an ultrasound and a CT scan after surgery. The goal was to see if ultrasound could detect leaks and measure the aneurysm sac accurately, potentially reducing the need for CT scans and their associated radiation and kidney risks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ultrasound contrast agent (Sonovue)
- What this could lead to
- If successful, this could make follow-up safer by replacing CT scans with ultrasound, reducing radiation exposure and kidney damage from contrast dyes.
- What could go wrong
- This is a small, completed study with only 40 participants. The ultrasound method may not be as accurate as CT for detecting all complications, and results may not apply to all patients.
