Outcome of renal stenting for renal artery coverage during endovascular aortic aneurysm repair

“Encroachment” of an aortic stent graft on the right renal artery, with the stented right renal artery.

Left renal artery “snorkel” stent running parallel to the main body component of an aortic stent graft.

A, Complete “encroachment” of an aortic stent graft is shown on the orifice of the left renal artery. B, A stent has been successfully placed into the left renal artery from the brachial approach. The arrows depict the proximal and distal extent of the renal artery stent.

A, A balloon-expandable stent is placed over a Rosen wire from a brachial approach, while the Zenith main body component is placed through the femoral access site. B, Simultaneous inflation of balloon-expandable right renal artery stent and a Coda balloon (Cook Inc) with a Palmaz aortic stent. C, Completion angiography shows a right renal artery “snorkel” stent.

In this fly-through view from a postoperative computed tomography scan in a patient who underwent placement of renal artery “snorkel,” the white arrow designates the renal artery “snorkel” stent; the block yellow arrow, the aortic stent graft with the Palmaz stent; and the thin yellow arrow, the superior mesenteric artery orifice.
