Successful treatment of iatrogenic renal artery perforation with an autologous vein-covered stent.

A 72-year-old woman developed severe flank pain associated with hemodynamic compromise immediately after a J-curve guidewire was inadvertently advanced into the right renal artery during cardiac catheterization. Contrast extravasation consistent with perforation of the main renal artery was seen on abdominal angiography. The perforation was successfully sealed using a premounted coronary stent that was covered with an autologous antecubital vein. Wide stent patency without aneurismal dilatation was confirmed on a 2-year follow-up renal angiogram. Copyright 2002 Wiley-Liss, Inc.
