The IMA comes off the aorta between the renal arteries and bifurcation. The IMA supplies the hindgut, which spans the distal 1/3 of transverse colon to upper portion of anal canal. Compromise of the IMA would lead to decreased blood supply to these structures, of which "Descending colon" is the only answer choice.
The graft is placed below the renal arteries and above the aortic bifurcation, which contains the IMA. IMA supplies the hindgut (distal 1/3 of transverse colon to to upper portion of the rectum).
