Anchor Balloon Technique.

Occlusion of an internal iliac artery or its branches is sometimes required prior to abdominal endovascular aneurysm repair. The Amplatzer vascular plug (AVP) is a useful device for this purpose, but it requires a large lumen catheter or guiding sheath to place it in the intended artery. We propose an anchor balloon technique for advancing this guiding sheath/catheter through a tortuous or angulated iliac artery for AVP placement.
