Abstract

Identification and control of responsible feeding arteries are crucial in treating type II endoleaks after endovascular aortic repair (EVAR). A 78-year-old female patient required management of a type II endoleak 8 years after EVAR. A persistent endoleak from the inferior mesenteric artery (IMA) enlarged the size of an aneurysm sac. Sac angiography from the IMA revealed a flow-through endoleak from the IMA to an aberrant renal artery (ARA). After coil embolization of the ARA through the sac together with the IMA, the sac shrank. Control of flow-through vessels may be essential for managing post-EVAR enlargement due to type II endoleaks.
