Abstract:
This report describes two cases of successful treatment of an internal iliac artery aneurysm (IIAA) type II endoleak utilizing a percutaneous transosseous access that could not be treated using an endovascular or standard percutaneous approach. A direct percutaneous approach through bone was chosen to avoid vital structures and the surrounding bowel. The procedure was successful and required minimal fluoroscopy time compared with other treatment options. We believe this procedure is an alternative to some of the more complex and technically challenging means of treating this lesion.
