A Novel Single-Branched Stent-Graft System for Aortic Dissection Involving the Aortic Arch.

Abstract

This report describes first-in-human experiences and early results of novel SureCham stent-graft system (SC) for aortic arch pathologies. The SC system consists of a modular design comprising a pre-fenestrated main stent-graft and a designed skirt-flared bridging covered stent to enhance the structural integrity of the stent connection. The SC incorporates a preloaded catheter for precise supraaortic cannulation, along with a precurved delivery system that enables navigation and accurate alignment. Collectively, these design features facilitate efficient reconstruction of the supraaortic branches while repairing aortic arch pathologies. We report 10 patients diagnosed with type B aortic dissections. Technical success, defined as accurate stent deployment, complete exclusion of pathology, patency of stent-grafts and absence of early endoleaks, was achieved in all patients. No major complications, such as death, stroke, and paraplegia, were observed. The novel SC system may be a safe and effective option for single-branch revascularization in endovascular repair. However, caution is warranted in extending its use to routine cases, given the limited evidence on outcomes.
