In this patient the IMA was pre-emptively em-
IMA in EVAR bolized with coils before the EVAR at the same
setting to reduce the risk of type II endoleak.
It can also be dealt with post-EVAR should a Type
II leak persists, by angiographic embolization
by accessing the IMA stump via the SMA or the
internal iliac artery.
This 76-year old man had a large Inferior mesenteric artery (IMA) arising from the anterior aspect of
his AAA. The CT images shows the anatomical relationship of the IMA and the infrarenal aorta. The
IMA is usually sacrificed both in EVAR and in open repair, without consequence. However in EVAR a
large patent IMA can be a cause of a persistent Type II endoleak.
