Atypical use of ALN inferior vena cava filters as protection devices prior to embolization of a large portosystemic shunt with amplatzer vascular plugs and Glubran 2 cyanoacrylate glue

Spontaneous portosystemic shunts usually develop as a result of portal hypertension caused by liver cirrhosis, and may subsequently lead to hepatic encephalopathy (1,2). In cases of severe portal hypertension, a part of the portal blood may reverse direction and pass through the portosystemic anastomoses into the systemic venous system.
