Fig. 1 Aortoscope assembly consists of 1.9 mm Intramed angioscope inserted through 9F balloon-tipped catheter; balloon insufflated with clear solution by way of 0.6 mm working channel.

Fig. 2 Digitized image of endoluminal pig aorta looking distally through aortoscope; large arrow shows right renal artery orifice; small arrow shows left renal artery orifice cannulated with angiogram catheter from femoral artery; bright spot in center is light reflecting off inside surface of aortoscope balloon; branching arteries and distal aortic lumen appear as red spots against pale color of aortic intima. (Resolution of image in photograph limited by lack of color and absence of consecutive real-time video images.)

Fig. 3 Diagram depicts endoluminal distances measured. R, Renal (inferior edge of most inferior renal artery orifice); T, trifurcation; D, device (proximal end of stent or graft); TAL is distance from inferior edge of most inferior renal artery orifice to distal aortic trifurcation; TAL = T - R; Device Placement Error is distance from inferior edge of most inferior renal artery orifice to proximal edge of stent or graft; DPE = D - R.

Fig. 4 Postmortem dissection of pig shows position of Palmaz stent (P308) used in abdominal aorta with aortoscopic guidance only; proximal end of stent aligned exactly with inferior edge of most inferior renal artery orifice.
