Thoracic aortic aneurysm

This registry tracked over 1,000 patients who received the Heli-FX EndoAnchor device during endovascular repair of aortic aneurysms. The device is designed to help hold the endograft in place and prevent leaks. Patients were followed for up to 5 years to see how safe and effectiv…

This study looked at 47 people with thoracoabdominal aortic aneurysms (a bulge in the main artery in the chest and belly). They received a custom-made stent graft (a fabric-covered metal tube) designed to fit their unique anatomy. The goal was to see if the aneurysm size stayed s…

This study looked at 80 adults having heart valve or aortic surgery to find out how long a special heart protection solution (Del Nido cardioplegia) keeps the heart safe during surgery. Researchers took blood samples at set times to see when heart injury began. The goal was to le…

This study tested a dye called pimonidazole to see if it can safely detect low oxygen levels (hypoxia) in the aorta of people having surgery for an ascending aortic aneurysm. Nine adults received the dye before surgery, and researchers measured how much of it was in the removed a…

This study tests two new monitoring techniques—long loop reflexes (F-waves) and near-infrared spectroscopy (NIRS)—to detect spinal cord ischemia early after thoracoabdominal aortic aneurysm repair. Current methods work during surgery but are too painful for awake patients afterwa…
