Endograft fenestration using a radiofrequency wire for embolization of type 2 endoleaks

Type II endoleaks are a common occurrence after endovascular repair of aortic aneurysm, with a significant subset requiring treatment. 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.
