摘　　要：目的　明确瘤体动脉分支和腹主动脉瘤 (AAA)腔内隔绝术 (EVE)后Ⅱ型内漏之间的关系。方法　回顾性分析 8例行EVE出现Ⅱ型内漏的AAA患者的临床资料。结果　所有患者瘤体上均有数目不等的通畅的动脉分支 ,术中并发即时性内漏。结论　瘤体上通畅的动脉分支是Ⅱ型内漏发生的主要原因 ,术后根据瘤径的变化采用相应的动脉栓塞治疗以防止动脉瘤继发性破裂。Objective To determine the association of patent sac branch vessels with early type 2 endoleak rate after endovascular exclusion (EVE). Methods 8 abdominal aortic anearysm patients in the presence of type 2 endoleak after EVE were retrospectively reviewed. Results All the patients with type 2 endoleak had multiple sac branch vessels preoperatively. Conclusions Patent sac branches play an important role in the pathogenesis of type 2 endoleak. If the excluded sac is increasing in size rapidly, the patent branches must be embolized promptly to avoid aneurysm rupture.
