Endovascular treatment of an unusual primary arterioportal fistula complicated by cavernous transformation of the portal vein caused by portal thrombosis

We describe an elderly woman who presented with an unusual primary arterioportal fistula and cavernous transformation of the portal vein caused by portal thrombosis, which were subsequently managed with endovascular coil embolization and transjugular intrahepatic portosystemic shunt using 2 stents after balloon remodeling. This case shows a rarely seen condition in the elderly and a novel management strategy that should be considered in the management of this complex disease.
