Exact deployment of stents in ostial renal artery stenosis using the stent tail wire or Szabo technique

This report describes a technique for the exact deployment of a stent in ostial renal artery stenosis (RAS) by using a second wire inserted through the last cell of a stent. This stent tail wire or anchor technique was first described by Szabo et al. (Am J Cardiol 2005; 96:212H) and facilitates precise aorto‐ostial stent deployment in cases of atherosclerotic RAS. The technique also helps to eliminate errors of improper stent positioning at this aorto‐renal junction, and may possibly minimize patient exposure to ionizing radiation and contrast dye. © 2009 Wiley‐Liss, Inc.
