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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
