In this report, we present a rare case of type 2 endoleak (T2EL) from an artery supplying the psoas major muscle, following an endovascular repair of a common iliac artery aneurysm (CIAA). A 79-year-old male underwent endovascular aneurysm repair (EVAR) for the right isolated CIAA using stent graft, with embolization of the ipsilateral internal iliac artery. The aneurysm was stable for 2 years, after which a follow-up CT revealed a 5 mm increase in the CIAA diameter and an endoleak of unknown origin. Conventional and CT angiographies revealed the source to be a branch from the ipsilateral deep circumflex iliac artery supplying the psoas major muscle that had developed an anastomosis at its terminal end with the vasa vasorum at the CIAA. Transarterial embolization of T2EL using glue was performed successfully, following which the T2EL disappeared.
在本报告中，我们介绍了一例罕见的2型内漏（T2EL）病例，该内漏发生在一名髂总动脉瘤（CIAA）血管内修复术后，源自供应腰大肌的动脉。一名79岁男性因右侧孤立性CIAA接受了血管内动脉瘤修复术（EVAR），使用了覆膜支架，并栓塞了同侧髂内动脉。动脉瘤稳定了2年，之后的随访CT显示CIAA直径增加了5 mm，且出现了原因不明的内漏。传统血管造影和CT血管造影显示，内漏源为同侧旋髂深动脉供应腰大肌的分支，该分支在其末端与CIAA的血管滋养血管形成了吻合。成功地使用胶水对T2EL进行了经动脉栓塞，之后T2EL消失。
