Applications of the Amplatzer Vascular Plug 4.

The purpose of this study was to present our initial experience with the Amplatzer® Vascular Plug (AVP) 4 in various arterial environments. This material was designed for the embolization of peripheral small vessels using a diagnostic catheter. Herein, the following three procedures using the AVP 4 were described: hemodialysis fistula occlusion as a treatment for the steal phenomenon, gastroduodenal artery embolization prior to liver radioembolization, and vertebral artery embolization for the treatment of subclavian artery pseudoaneurysm and arteriovenous fistula. All of the treated vessels were successfully occluded, and the devices remained in the original locations and configurations during the follow-up period. When compared with the previous generation of vascular plugs, the AVP 4 allows faster and safer procedures with less radiation exposure to the patients and angiography team.
