RESUMO
Objective To cvaluate the efficacy and safety of HabibTM VesOpen intravascular radiofrequency catheter percutaneous radiofrequency ablation combined with TACE in the treatment of portal vein tumor thrombus of primary hepatocellular carcinoma.Methods Thirty-nine patients with primary hepatocellular carcinoma complicated with portal vein thrombosis were treated with HabibTM VesOpen intracavitary catheter ablation combined with TACE.The postoperative success rate,complication,blood index,α-fetoprotein (AFP),portal vein patency and tumor thrombus imaging changes were assessed.Results All of 39 patients underwent surgery successfully without occurrence of perforation,infection,hepatapostema,intra-abdominal hemorrhage nor other complications associated with surgery.Blood routine examinations (WBC,RBC,PLT) after 2 weeks and 4 weeks of surgery had no statistical difference compared with those of preoperation.Liver function indexes including ALT,AST,ALB had statistical difference before and after the surgery except for TBIL.AFP had statistical difference before and after surgery.Doppler ultrasonography after 4 weeks showed blood flow in original blocked portal vein.Enhanced CT or MR examinations after 8 weeks on the abdomen,suggested that tumors were shrinked or disappeared.Conclusion Radiofrequency catheter ablation with intracavitary radiofrequency catheter of HabibTM VesOpen is an effective method in the treatment of portal vein tumor thrombus in primary hepatocellular carcinoma.
