Stent-assisted Coil Embolisation of Wide-necked Renal Artery Aneurysms

AbstractIntroductionA wide-necked saccular renal artery aneurysm (RAA) arising from the left posterior segmental was not reported before and can be treated by stent-assisted coil embolisation.Case reportA 69-year-old man presented with RAA arising from left posterior renal segmental artery, which was a saccular wide-necked RAA that was 2.5 cm in size. He underwent endovascular coil embolisation assisted with a self-expanding nitinol stent that originally had been constructed for the treatment of intracranial aneurysm. Distal renal infarction occurred in stented segmental artery.DiscussionDistal infarction after stent-assisted coil embolisation should be considered as a possible complication in the treatment of RAA in relatively small renal segmental artery
