复杂腹主动脉瘤内脏分支重建技术评价

Technical evaluation of reconstruction of visceral vessel branches in complex abdominal aortic aneurysm

随着腔内治疗技术和器材的发展,腹主动脉瘤腔内修复术已成为腹主动脉瘤的首选治疗方式。而近端锚定区不良以及累及内脏分支的复杂腹主动脉瘤则是制约该技术发展和影响其治疗效果的关键因素。平行支架、开窗支架、分支支架、多层密网支架和去分支等技术是目前重建内脏分支的主要方法,笔者结合相关研究结果对上述技术进行简要讨论,以期为复杂腹主动脉瘤的腔内治疗提供参考。

With the development of endovascular treatment and interventional instruments,endovascular aneurysm repair has become the preferred method for the treatment of abdominal aortic aneurysms.Poor proximal landing zone and abdominal aortic aneurysms involving visceral branch arteries are the main factors restricting the application and affecting the efficacy of this technique.The techniques such as parallel,fenestrated,branched and multi-layered flow-modulating stent grafts and aortic debranching are the main methods for the revascularization of visceral branch arteries at present.Here,the authors briefly discuss above techniques based on relevant research results,so as to provide recommendations for the endovascular treatment of complex abdominal aortic aneurysms.
