Findings of angiography. a Angiography via the celiac artery was performed to create a portogram via the APF, and portography clearly revealed hepatofugal flow of the portal vein (blue arrows). Portography also showed that the stump of the anterior portal vein had developed a PVA with a diameter of 40 mm (orange arrows). b Selective catheterization of the common hepatic artery clearly demonstrated the APF at the stump of the anterior branches (red arrows). A definitive diagnosis of PVA due to APF was made. An adequate length of APF to perform embolic therapy was confirmed. c Selective embolization of the anterior hepatic artery was accomplished by placement of several titanium coils (yellow arrow). Blood flow through the APF was drastically reduced. d Arteriography via the superior mesenteric artery showed hepatopetal portal flow (purple arrows)
