    Introduction and aims: Endovascular treatment of thoracoabdominal aortic aneurysms in patients with complex anatomy represents a challenge for the vascular surgeon. The new device based on the Dominus platform (BRAILE Biomedica®, São José do Rio Preto, Brazil) modified by Endovsmart s.r.l.™ (Bergamo, Italy) based on the modulation of the radial force and with the possibility of circumferential fenestrations can increase the technical success and simplify the implant procedure.

    Materials and methods: From August 2018 to April 2024, 35 patients were treated: 16 with AAA, 12 with TAA, 5 with aortic arch aneurysms and 2 with TAAA, characterized by considerable anatomical complexity (angulation of the aortic arch>75°, descending thoracic aortic angulation 30°, alpha angle 90°, aortic diameter >40mm at the level of the renal aorta, etc.). The primary end points were technical success and 30-day morbidity/mortality. Follow-up was performed by clinical/laboratory examination and CT angiography at 1, 3, 6 months and then annually.

    Results: The 30-day technical success was 94.7%; 1 death from respiratory complications in intensive care was documented, 1 case of worsened renal function due to partial thrombosis of the renal arteries. One case of suspected graft infection was reported 13 months after implantation and it is under investigation.

    During the follow-up (max 42 months) no further complications were found, the CT scans confirmed the good operative result with patency of the graft and visceral vessels and absence of significant endoleaks.

    Conclusion: In this preliminary monocentric experience, the new modified Dominus BRAILE Biomedica® device proved to be effective or the treatment of complex aneurysms of the thoraco-abdominal aorta that are difficult to treat with other endografts. Further scientific analyzes and larger follow-up will be needed to confirm these preliminary studies.
