主髂动脉闭塞症指以动脉粥样硬化为主要原因的腹主动脉远端、主髂动脉分叉部血管狭窄或闭塞，导致盆腔、下肢缺血的一类疾病。外科开放手术一直是复杂主髂动脉病变的主要治疗手段。近年来，随着血管腔内技术的发展，其治疗理念有了极大改变。越来越多的证据表明，腔内治疗的中远期效果已不劣于传统的开放手术，成为主髂动脉闭塞症的首选治疗方案。“,”Aortoiliac occlusive disease (AIOD) refers to the stenosis and occlusion of the distal abdominal aorta and(or) bifurcation of the aortoiliac artery,which is mainly caused by atherosclerosis,leading to pelvic and lower limb ischemia.Open surgery has always been the main treatment for complex AIOD.However,in recent years,with the development of endovascular surgery technologies and medical instruments,its treatment concept has been greatly changed.More and more clinical evidence has proved that the long-term efficacy of endovascular therapy is not inferior to that of traditional open surgery,so minimally invasive endovascular therapy has become the preferred treatment for AIOD.
