“Staged” kissing stent placement under computed tomographic angiography guidance for a bilateral aortoiliac occlusion

Abstract

A 64-year-old female with chronic hemodialysis complained of a worsening of bilateral intermittent claudication. Computed tomographic angiography (CTA) demonstrated severe calcified bilateral aortoiliac occlusions. The kissing stent placement was therefore attempted: A 10 × 60 mm SMART stent was placed into the right aortoiliac lesion at the 1st session, and a 10 × 60 mm SMART stent was placed into the left aortoiliac lesion parallel with the previous SMART stent at the 2nd session, thus completing the "staged" kissing stent placement. CTA indicated the penetrating point in the calcified plaque clearly, and this case suggested the usefulness of CTA guided percutaneous peripheral intervention.
