case_images: From the aortic centerline analysis, the patient had short bilateral aortoiliac lengths from the lowest renal artery to external iliac artery and internal iliac artery bifurcation (right = 164 mm, left = 167 mm).

case_images: Phoenix, AZ) to preserve both IIA infeasible (Figure 1).
case_images: Two cross-over chimney stent grafts (thick black arrow) were deployed simultaneously with the iliac limb extension stent (star) and parallel grafting at the proximal end of iliac branch endoprosthesis. The postoperative angiography showed patent bilateral internal iliac arteries (thin black arrow). On the axial view of the computed tomography scan, one end of the cross-over chimney stent grafts (thin white arrow) was deployed within the proximal end of right iliac branched device (thick white arrow). The other end was deployed parallel to the ipsilateral left iliac limb extension stent (thin white arrow).

case_images: These two cross-over stent grafts were simultaneously deployed with parallel 27 mm iliac extension from the contralateral gate of the Excluder bifurcated device to the right IBE of which the proximal diameter is 23 mm (Figure 2).
case_images: Computed tomography showed patent right internal iliac artery (arrow) from the iliac branch device and patent left internal iliac artery (star) from the cross-over chimney stent grafts.

case_images: Follow-up computed tomography (Figure 3) and three-dimensional angiography (Figure 4) 10 days after the procedure showed complete aneurysmexclusion with flow preservation to bilateral IIAs.
case_images: Computed tomographic angiography showed the morphology of cross-over chimney grafts (star) and the parallel graft with the iliac branch device (arrow).

case_images: Follow-up computed tomography (Figure 3) and three-dimensional angiography (Figure 4) 10 days after the procedure showed complete aneurysmexclusion with flow preservation to bilateral IIAs.
case_images: Computed tomography showed the patent cross-over chimney stents (thick arrow) 2 years after the surgery.
