Late aortic dislocation of a stent following stent angioplasty for ostial renal artery stenosis.

A patient with left RAS was treated by stent angioplasty followed by a multivessel percutaneous coronary intervention. Six months later, an aortic dislocation of the stent was diagnosed. The fully expanded stent was caught with a balloon catheter and fixed in the left external iliac artery. Stent migration after initially successful stent angioplasty for RAS is possible. Fully expanded, dislocated balloon-expandable stents can be secured by implanting them into the iliac artery.
