The Clinical Study Of Ultrasound-guided Percutaneous Implantation ¹²⁵I Seed For Central Hepatic Cancer

Objective:To access the validity of Ultrasound-guided percutaneous 125 I radioactive seeds implantation for treatment of central hepatic cancer.Materials and Method:15 patients with central hepatic cancer were in our hospital. All of patients underwent ultrasound-guided percutaneous 125 I radioactive seeds implantation. Intraoperative ultrasound guided real-time observation of tumor and its surrounding structures, to choose the best puncture path, adjust the direction of the probe and the needle angle from the bile duct, pancreatic duct and visible blood vessels, according to the preoperative TPS embedded particles. Postoperative 1-12 months review, observed local control of tumor, postoperative complications,operation time and survival rate of patients.Result:Patients were all successful completion of particle implantation in one-time. 1 cases had epigastric discomfort, 1 cases had implantation metastasis of needle route, and the other patients had no complication such as biliary fistula, infection, bleeding, particle displacement and other serious complications. The local control of tumor was evaluated by CT in third months after operation. In group A, CR 3, PR 10, SD 2, PD 0,and total effective rate were 86.7%. The average operation time was 0.85±0.15 h.Conclusion:Ultrasound-guided percutaneous 125 I radioactive seeds implantation for treatment of central hepatic cancer had many advantages, such as little operative trauma, good local control of tumor and high survival rate.
