There are a significant subset of type II endoleaks that are not amenable to established treatment routes, such as transarterial, transcaval, or translumbar. We report two cases of a successful transgraft approach to type II endoleak embolization using the Powerwire radiofrequency guidewire. The use of the radiofrequency guidewire to accomplish transgraft embolization has not been previously reported. This is a useful technique to have in the arsenal for treating type II endoleaks.

Transgraft access is a more recently described technique. Two different techniques have been described to create the fenestration: laser catheter and trans-septal or transjugular needles.5, 6 The Baylis Powerwire was originally designed to fenestrate the atrial septum. The use of a radiofrequency guidewire for transgraft embolization has not been previously described. Here we present two cases of type II endoleaks that were successfully treated with transgraft embolization with the Baylis Powerwire radiofrequency guidewire.

A 74-year-old man with a Medtronic Talent endograft presented with a persistent type II endoleak with sac growth. Three prior attempts at embolization via transarterial and translumbar approaches were unsuccessful. Imaging showed the endoleak nidus positioned posterolateral to the right iliaclimb (Fig 1, A) . Via percutaneous femoral access a Tourguide 6.5F steerable sheath (Medtronic) was opposed to the wall of the iliac limb opposite the endoleak nidus that had been marked using fusion guidance.
