Thoracic aortic aneurysm

This study tracks the safety and effectiveness of a stent graft device used to treat aneurysms, dissections, or trauma in the aortic arch (the curved part of the main artery from the heart). Researchers will follow 75 patients in Japan who receive the device, monitoring for compl…

This study tests whether taking aspirin after a minimally invasive aortic arch repair can prevent strokes, a common complication. 224 patients will be randomly assigned to take aspirin for 3, 6, or 12 months. The researchers will track stroke rates, bleeding risks, and other outc…

Aortic arch surgery temporarily cuts blood flow to the brain, which can leave patients with lasting thinking and memory problems. Researchers at Seoul National University Hospital are testing whether anesthesia with remimazolam, rather than propofol, lowers the chance of that cog…

This study tests whether ultrasound of the optic nerve sheath, a marker of brain pressure, can track brain swelling during ascending aortic surgery. Researchers will measure the optic nerve sheath diameter before, during, and after surgery in 134 adults undergoing this procedure.…

This study explores whether ultrasound can reliably measure aneurysms in the descending thoracic aorta, the part of the main artery that runs through the chest. Researchers will compare ultrasound measurements with standard CT scans in about 60 adults, including some with known a…

This registry will follow 400 people with complex aortic aneurysms who are treated with GORE devices that help keep blood flowing to vital organs. The goal is to see how well the devices work and how safe they are in everyday medical practice. Participants must need at least one …
