The aim of the study is to evaluate the practicability and therapeutic efficacy of 125iodine seeds implantation percutaneously for portal vein tumor thrombosis (PVTT) in patients with hepatocellular carcinoma (HCC). Nineteen patients with HCC accompanied with PVTT received ultrasound-guided implantation of 8-0 125iodine seeds, 8?mm apart within the portal vein tumor thrombi. The patients were followed up postoperatively for a period of 3-2?months. The successful rates of the procedure, postoperative changes of liver and renal function, hemogram, complications and therapeutic response were monitored. 125I seeds were successfully implanted in the portal veins in all patients without serious complications. During the follow-up period, the portal vein tumor thrombi all shrunk obviously. Percutaneous implantation of 125iodine seeds into the portal vein is an effective and safe treatment for PVTT accompanying HCC.
