Catheter-Based Bailout Techniques for an Interrupted Deployment of the Excluder Endograft Due to Broken Deployment String

In this report we describe catheter-based bailout techniques for when the distal end of the ipsilateral leg of an Excluder endograft has remained undeployed due to a broken deployment string. We attempted to advance a percutaneous transluminal angioplasty (PTA) balloon into an undeployed leg via the brachial artery, but were unable to do so. The delivery catheter was then pulled out through the undeployed leg while the main body was supported by a dilated touch-up balloon to prevent stent graft migration, which subsequently enabled insertion of the balloon via the ipsilateral femoral artery. Complete deployment was accomplished by balloon dilation. Although this is situation is extremely rare, it should be recognized and catheter-based strategies should be known for dealing with this complication.
