Endovascular AVF arteriovenous fistula (AVF) formation is a relatively new way to provide life-saving hemodialysis access without surgical intervention. In this technique, endovascular application of a radiofrequency pulse is used to create a fistula between ulnar artery and ulnar vein or radial artery and radial vein. Generally, patients are able to undergo endovascular AVF quicker than they would surgical fistula formation, and with endovascular AVF, standard surgical options can still be pursued in the future. There is minimal scarring with the procedure, which is overall well tolerated. Although the technical aspects may seem daunting at first, endovascular AVF is a relatively straightforward procedure that can be done on an outpatient basis.

Educational Goals / Teaching Points
The goal of this educational exhibit it is to teach interventional radiologists about endovascular AVF and the technical aspects of performing the procedure including anatomical considerations, how to ensure the right patient undergoes the procedure, how to perform the procedure, and what radiologic studies to order before and for follow-up.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This educational exhibit will feature step by step pictorial instructions demonstrating the technical aspects of the procedure.

Endovascular AVF formation is a relatively new and potentially life-saving procedure that can create reliable hemodialysis access in appropriate patients. It is important for interventional radiologists to be aware of endovascular AVF and how it is performed.
