Abdominal aortic aneurysm rupture after endovascular aneurysm repair (EVAR) is rare, but remains a significant limitation of endovascular technology. Preservation of the endograft during open conversion of a post-EVAR rupture has been shown to be associated with improved perioperative outcomes. An interposition Dacron graft with felt pledgets is a novel bail-out option for the open reconstruction of a type III endoleak with total endograft preservation. This technique is useful in high-risk patients presenting with ruptured abdominal aortic aneurysm after EVAR and no clear source of endoleak.
血管内动脉瘤修复术（EVAR）后腹主动脉瘤破裂罕见，但仍是血管内技术的一个重大局限。在EVAR术后破裂行开放转换手术期间保留血管内移植物已被证明与围手术期预后改善相关。带毡片的涤纶移植补片是一种用于Ⅲ型内漏开放重建并完全保留血管内移植物的新型补救选择。该技术对EVAR术后出现腹主动脉瘤破裂且无明确内漏来源的高危患者有用。
