UNASSIGNED: A state-of-the-art TEVAR was modified by separating the fabric from the z-stents and suturing a hand-sewn bovine pericardium tube to the bare metal. Feasibility of preparation, re-sheathing, and delivery is demonstrated in an ex-vivo model.
UNASSIGNED: This first xenogeneic stent graft could be manufactured and deployed successfully. In the future this may provide a bridging alternative for high-risk patients with infected native aortic aneurysm or aortic fistulas, eventually followed by surgical or thoracoscopic/laparoscopic debridement. Further studies on simulators or animal models are needed to test the technique and investigate its long-term durability. Additionally, this study prompts reflection on whether materials currently used should be further developed to prevent graft infections.
■通过将织物与z-支架分离并将手工缝制的牛心包管缝合到裸金属上来修改最先进的TEVAR。准备的可行性,重新护套,和递送在离体模型中证明。
■可以成功制造并部署第一个异种支架移植物。将来,这可能为感染天然主动脉瘤或主动脉瘘的高危患者提供桥接替代方案。最终进行手术或胸腔镜/腹腔镜清创。需要对模拟器或动物模型进行进一步研究,以测试该技术并研究其长期耐久性。此外,这项研究促使人们反思是否应进一步开发目前使用的材料以防止移植物感染。
