Coil embolisation of the internal iliac arteries prior to EVAR is considered standard treatment to prevent a type 2 endoleak when extending an iliac limb into the EIA. Type 2 endoleaks that arise from a non-coil-embolised internal iliac artery can be challenging to treat due to difficult access.
We present a case of a type 2 endoleak from the internal iliac artery that was not coiled prior to EVAR. This was treated with retrograde embolisation of the internal iliac artery via direct puncture of a branch from the buttock and closure of the arteriotomy was achieved using an Angio-Seal (Terumo) device that was deployed in an off-label manner to allow visualisation.
This is a viable technique for treating type 2 endoleaks when antegrade access to the internal iliac artery is lost due to the presence of the stent graft and the arteriotomy can be safely closed with an Angio-Seal.
在进行腹主动脉瘤腔内修复术(EVAR)之前,对髂内动脉进行弹簧圈栓塞被认为是标准治疗方法,可防止在将髂支延伸至髂外动脉(EIA)时出现2型内漏。由于进入困难,源自未进行弹簧圈栓塞的髂内动脉的2型内漏可能难以治疗。
我们报告一例在EVAR之前未对髂内动脉进行弹簧圈栓塞而出现的2型内漏病例。通过直接穿刺臀部的一个分支对髂内动脉进行逆行栓塞治疗该内漏,并使用以非标签方式部署的Angio-Seal(泰尔茂)装置实现动脉切开术的闭合,以利于可视化。
当由于存在覆膜支架而无法顺行进入髂内动脉且动脉切开术可使用Angio-Seal安全闭合时,这是一种治疗2型内漏的可行技术。
