Representative images of irradiation stent placement for portal vein tumor thrombosis (PVTT). Representative images of a 50-year-old male patient who underwent irradiation portal vein stent placement for PVTT. (A) Portography showed a filling defect at the right branch of the portal vein and proximal main portal trunk (Vp4). (B) The self-expandable ¹²⁵I radioactive seed-loaded stent was first inserted under fluoroscopic guidance. (C) A self-expandable nitinol stent was introduced and overlapped the outer stent within. (D) Portography showed immediate recanalization of the portal vein.
