Key Clinical Message:
Embolization with IMPEDE embolization plug cannot be confirmed on site. Therefore, we propose that the diameter of the device selected be up to 50% larger than the vein diameter to prevent embolization failure and recanalization.
Abstract:
Balloon-occluded retrograde transvenous obliteration and percutaneous transhepatic obliteration (PTO) are performed for treating sporadic gastric varices. IMPEDE embolization plug has been recently developed for these procedures; however, no studies have reported its use. This is the first report on its use in PTO of gastric varices.
