TBE stent-graft repair for thoracic aortic disease with Zone 2 proximal landing in Japan
Official title: GORE® TAG® Thoracic Branch Endoprosthesis Zone 2 Post-Market Surveillance in Japan
Run by W.L.Gore & Associates · NCT07049913 · Data updated 2026-11-12
This project will try the GORE TAG Thoracic Branch stent graft in people in Japan who need repair of descending thoracic aortic aneurysm, traumatic transection, or complicated type B dissection with a proximal landing in Zone 2.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients in Japan with descending thoracic aortic lesions who meet the Japan package insert anatomical criteria and have thoracic aortic aneurysm, traumatic transection, or complicated type B dissection not controlled by medical therapy.
✕Probably not a fit
Patients who do not meet the device's anatomical requirements or whose conditions can be managed without endovascular repair are unlikely to benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a post-marketing observational surveillance using the GORE TAG Thoracic Branch Stent Graft System to confirm safety and effectiveness when the device is landed proximally in aortic Zone 2. Patients are enrolled if they meet the Japan package insert anatomical requirements for preserving left subclavian artery blood flow, including thoracic aortic aneurysm, traumatic transection, or complicated Stanford type B dissection not controlled by medical therapy. Treatments follow routine clinical care at participating centers and outcomes and adverse events are collected during follow-up. The registry-style design is non-randomized and intended to capture real-world device performance in the post-marketing period.
Why it matters
Potential benefit: If successful, this could support a treatment option that repairs descending thoracic aortic lesions while preserving flow to the left subclavian artery.
How similar studies have gone: Prior observational series of GORE thoracic branch and other branched endografts have shown promising outcomes, but use specifically landing in Zone 2 is relatively recent and evidence remains limited.
