The endovascular exclusion is an effective treatment of aortic aneurysm diseases in frail and elderly patients who cannot suffer the open surgery. However, as the key treatment device of this technique, traditional stent-grafts are not suitable to treat complex aortic aneurysm diseases in emergency. The emergence of the fenestrated stent-graft and in-situ fenestration has brought new dawn to the treatment of these patients. This study reviews the advances in complex aortic aneurysms treated by the fenestrated stent-graft and the in-situ fenestration. In addition, the novel concept of the fabric structure designed for "in-situ fenestrated stent-graft" is proposed for the in-situ fenestration technique. It is expected to break through the bottleneck of the present fenestrated stent-grafts. It would be beneficial to the bailout of complex aortic aneurysm diseases and thereby benefitting more patients.
腔内修复术可有效治疗无法耐受开放手术的年老体弱患者的主动脉瘤疾病，但该技术的关键治疗器械覆膜支架并不适用于复杂主动脉瘤疾病的急诊治疗。然而，开窗型覆膜支架及原位开窗技术的出现为这些患者的治疗带来了新的曙光。本文综述了针对复杂主动脉瘤疾病治疗使用的开窗型覆膜支架及原位开窗技术所用的常规覆膜支架的研究进展；并提出了面向原位开窗技术的"原位开窗用覆膜支架"的织物覆膜的结构设计理念。以期突破现有开窗型覆膜支架的瓶颈，有利于突发性复杂主动脉瘤疾病的紧急救治，从而让更多的患者受益。.
