Mini ultrasound inside aorta could save organs after emergency surgery

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.
