Mini ultrasound inside aorta could save organs after emergency surgery
NCT ID NCT04907071
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tested whether a small ultrasound device placed inside the aorta can quickly identify organs not getting enough blood after surgery for aortic dissection (a tear in the main artery). The device was used in 50 patients right after repairing the tear. The goal was to see if real-time imaging could catch blood-flow problems before they cause permanent damage, such as kidney failure or bowel injury. The study measured safety and effectiveness by tracking deaths, organ damage, and major complications.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Intravascular ultrasound (IVUS) catheter
What this could lead to
If successful, this technique could help surgeons detect and treat organ blood-flow problems during the same surgery, potentially reducing serious complications.
What could go wrong
This is a small pilot study with only 50 participants, so results may not apply to all patients. The device is used during a complex emergency procedure, and risks include vascular injury or false readings.
