Comparing two ways of making a hole in a stent to keep arm blood flowing
Part of Heart & circulation clinical trials.
This study is looking at two ways to create an opening in a stent so that blood can still flow to the left arm when the stent must cover the left subclavian artery during repair of the aorta. It compares making the opening before the stent is inserted versus after it is in place, to see which is safer and more effective.

Who can take part
- You must be between 18 and 79 years old.
- You need to have a confirmed problem in the large artery in your chest, such as a tear (dissection), a bulge (aneurysm), an ulcer, or a blood clot in the wall.
- Your doctor must have decided that you need a stent to repair the artery, and that the stent will cover the opening of the left subclavian artery (the artery that goes to your left arm).
- The problem must be close to the left subclavian artery but not involve the left common carotid artery (the artery that supplies blood to your head and neck).
- Your blood vessels in the groin, pelvis, or arm must be suitable for the procedure.
- You must be able to tolerate the procedure and be expected to live for at least another 12 months.
- You must not have had a previous stent placed in your aorta for this condition.

This trial tests two different stent procedures to repair a torn aorta in people with severe narrowing that limits blood flow to organs. It compares the usual stent method with a new one to see which gives better results.
This trial tests a special stent graft for people with a type B aortic dissection that needs a new blood flow path to the left subclavian artery. The device is placed in the aortic arch to repair the tear and keep blood flowing normally.
This study looks at different ways to keep blood flowing to the left arm when repairing the aorta in the chest. It aims to find which method works best for people with certain aortic conditions.
This study tests whether repairing an enlarged or tearing (dissection) thoracic aorta using a catheter-based procedure can be safer for people who are high-risk for open surgery. It uses specialized stent grafts placed through blood vessels to seal the problem and prevent complications.
This study compares two surgical techniques for repairing a tear in the main artery (aorta) during an emergency. It aims to see if adding a stent (a small mesh tube) to the standard repair improves outcomes. Participation may help improve treatment for this serious condition.
This trial tests a specialized stent (a small mesh tube) placed inside the chest and belly aorta to treat a thoracoabdominal aortic dissecting aneurysm. It may help prevent the artery from getting bigger or causing dangerous bleeding by supporting the weakened area from inside.
