Reducing air bubbles during aortic repair with carbon dioxide

Type B Acute Aortic SyndromeThoracic and Thoracoabdominal Aneurysms With Crawford Extent I, II, III, or IV

Part of Brain & nervous system, Heart & circulation clinical trials.

This trial tests a special flushing method using carbon dioxide gas to prevent air bubbles from entering the bloodstream during a procedure to fix the main artery in the chest. This could help avoid strokes or other complications.

Breathing extra carbon dioxide during surgery to prevent brain injury

This trial tests whether giving extra carbon dioxide during surgery can reduce the chance of new brain or nervous system injury after surgery for a sudden, life-threatening tear in the big artery (type A aortic dissection). It may help by protecting the brain while the surgical team repairs the artery.

Custom stent-graft procedure for complex aortic aneurysm repair

This study tests a new way to repair a complex aortic aneurysm (a bulge in the main artery) using a special procedure that helps keep blood flowing to your vital organs. It may help people who are not candidates for standard surgery. The goal is to see if this approach is safe and works well.

Balloon-assisted stent repair for chest aortic aneurysm

This study looks at whether using a special balloon in the heart during a chest aortic repair helps the stent graft stay in place and improves outcomes. It may help patients whose stent is placed in the upper part of the aorta.

Breathing gas study during clot removal for stroke

This Phase 2 trial tests whether changing breathing gas (CO₂ level) during a mechanical procedure to remove a brain blood clot can improve outcomes for acute ischemic stroke. It may help by protecting the brain during the clot-removal procedure under general anesthesia.
