腔内修复术中应用 Viabahn 支架重建肠系膜下动脉--2例报告

摘要

[Summary] From May 2015 to December 2015, two cases of aortic aneurysm underwent endovascular aortic repair (EVAR), and simultaneously the inferior mesenteric artery ( IMA) was implanted with the Viabahn stent-graft to reconstruct blood perfusion .The case one patient , which was suffered with abdominal aortic aneurysm ( AAA) coexisting with bilateral common iliac aneurysm and combined with Riolan aortic arch , underwent EVAR successfully , with IMA implanted with Viabahn stent using the “Chimney”technology.After 3 months, aortic CTA showed successfully aneurysm isolation and well patent Viabahn stent .The case two patient, which was suffered with huge right common iliac aneurysm , underwent EVAR successfully , with the internal iliac artery occlusion with coin and IMA reconstruction with Viabahn stent .After 6 months, aortic CTA showed successful aneurysm isolation , as well patent Viabahn stent .We deem that EVAR and IMA revascularization using Viabahn stent-graft have satisfactory short-term outcomes in patients with complex AAA , which could prevent intestinal ischemia and simplify the operation .%2015年5～12月我科行主动脉腔内修复术（ endovascular aortic repair ， EVAR）治疗腹主动脉瘤（ abdominal aortic aneurysm， AAA），同期应用Viabahn支架重建肠系膜下动脉（inferior mesenteric artery， IMA）2例。1例肾下型AAA合并双髂总动脉瘤样扩张，Riolan动脉弓形成，行EVAR治疗AAA，同期采用“烟囱”技术IMA内植入Viabahn支架成功，术后3个月随访复查CTA示支架位置良好，瘤体隔绝成功，Viabahn支架通。。1例右侧髂总动脉巨大动脉瘤，行EVAR治疗髂总动脉瘤，髂内动脉弹簧圈栓塞，IMA内植入Viabahn支架成功，术后6个月随访复查CTA示支架位置良好，瘤体隔绝成功，Viabahn支架通。。我们认为复杂AAA应用Viabahn支架合理重建IMA预防肠缺血，简化手术操作，近期疗效满意。
