"Candy Cane" Guide Catheter Extension for Stent Delivery.

Stent delivery to a native coronary artery lesion located proximal to the anastomosis of a bypass graft can be challenging due to severe tortuosity. Guide catheter extensions, such as the GuideLiner, can facilitate equipment delivery. In the presented case, a 180° anastomotic bend in the saphenous vein graft resulted in several failed attempts at stent delivery. A 6 Fr guide catheter extension was then advanced through the extreme angulation at the SVG anastomosis using a distal-anchor technique and assuming a "candy cane" configuration, enabling stent delivery.
