Fig. 2A Images show right common and external iliac arteries 6 months
after placement of self-expandable nitinol stent (diameter, 10 mm; length, 68
mm) in 56-year-old woman. Nonsubtracted (A) and subtracted (B)
digital subtraction angiography (DSA) images show diagnostic catheter crossing
stent. Dimensions of stent are better appreciated on nonsubtracted than on
subtracted image (stent ends indicated by arrows). In-stent stenosis
of about 50% (arrowhead) due to intimal hyperplasia in distal portion
of stent is visible.
