Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults over 18 with thoracic aortic aneurysms, acute aortic dissections, or congenital aortic anomalies requiring repair of multiple segments.
✕Probably not a fit
Patients who are unfit for open surgical repair or have severe brain malperfusion may not benefit from this study.

What this trial studies
This study evaluates the safety and preliminary effectiveness of a novel hybrid repair technique called Branched Stented Anastomosis Frozen Elephant Trunk Repair (B-SAFER) for patients with thoracic aortic pathologies. It focuses on individuals requiring repair of the aortic arch proximal to the innominate artery, utilizing a physician-modified endovascular stentgraft. The study is a prospective, single-center, non-blind, non-randomized investigation that will assess the functionality of the device and its components during the implantation process.
Why it matters
Potential benefit: If successful, this technique could provide a safer and more effective option for patients with complex thoracic aortic conditions.
How similar studies have gone: While this approach is innovative, similar studies have shown promise in hybrid repair techniques for thoracic aortic conditions.
