Researchers are evaluating the safety and early effectiveness of a new surgical technique called Branched Stented Anastomosis Frozen Elephant Trunk Repair B-SAFER for treating complex thoracic aortic diseases. This technique uses a specially modified endovascular stentgraft to repair multiple damaged areas of the aorta, particularly where the aortic arch is involved. The study aims to assess how well this hybrid repair method works and how safe it is for patients with conditions like thoracic aortic aneurysm, aortic dissection, or congenital aortic anomalies. The treatment involves implanting a physician-modified endovascular stentgraft designed for the proximal aorta. This simplified hybrid frozen elephant trunk repair technique is performed as part of the surgical procedure. The study focuses on device performance, including the functionality of multiple components used during the operation. Participants will undergo this device implantation as the experimental intervention. During the study, participants will be closely monitored for outcomes such as survival, stroke, paralysis, and technical success shortly after treatment. Follow-up assessments will include checking the patency and sealing of the graft components at hospital discharge or one month. Longer-term monitoring up to three years will evaluate complications like device failures, re-operations, infections, and other adverse events. This comprehensive follow-up helps to understand both the safety and durability of the B-SAFER repair over time.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | B‑SAFER (investigational frozen elephant trunk repair) | Conventional total arch replacement (cTAR) or hemi‑arch repair |
|---|---|---|
| What it is | A physician‑modified branched stented frozen elephant trunk repair (B‑SAFER) technique for total aortic arch replacement in patients with multisegment thoracic aortic disease | Established open surgical repair using conventional total arch replacement or frozen/hemi‑arch techniques |
| Role in the trial | Investigational intervention under evaluation across all participants | Not used as a randomized comparator in this study; provided here for context |
| Primary use | To repair multiple diseased or damaged thoracic aortic segments using a single hybrid stented-arch technique | To replace the aortic arch and repair segments through conventional open surgery or frozen/hemi‑arch approach |
| How it is performed | Physician‑modified endovascular stent graft deployed as branched frozen elephant trunk in total arch repair | Open surgical replacement of the arch and hemi‑arch with optional frozen elephant trunk graft |
| Evidence status | Early safety and applicability demonstrated; outcomes still under investigation | Long‑standing surgical approach with observational support but limited randomized trials comparing with novel techniques |
| Important limitations | Single‑group design without randomized control; long‑term outcomes not yet available | Evidence largely observational; direct comparison to B‑SAFER limited |
