Feb 20, 2013 · Usual practice involves removing the buddy wire as soon as a stent is positioned in the target lesion, thus before stent delivery. Published in 2007 by Kaluski et al. , the method of intentionally ‘burying’ or ‘jailing’ a buddy wire by stenting a proximal lesion was again described by Bagnall and Spratt in 2009 . The ‘buddy in jail’ wire secures the guiding catheter and provides a better support.Author: Vincent Dangoisse, Antoine Guédès, Erwin Schroëder
