ABSTRACT
Objective To evaluate the blood supply features and effectiveness of arterial chemoembolization for pedunculated hepatocellular carcinoma.Methods Angiography and chemoembolization via supplying blood arteries of tumor were performed in five patients with pedunculated hepatocellular carcinoma.Interventional procedure was carried out with tumor vascular infusion of 350 mg hot elemene emulsion and tumor embolization by cisplantin-lipidol emulsion(cisplantin 60-80 mg+lipidol 8-15 ml)and glutin.Results Ten interventional procedures(TACE)were undertaken in 5 patients.Angiography showed that tumor blood supply mainly coming from collateral circulation adjacent to the tumors,but partially from hepatic artery.Tumor sizes decreased from 30% to 50% in 5 cases,and AFP declined in 4 cases after the treatment. Conclusion Pedunculated hepatocellular carcinoma possessing different blood supply features from intrahepatocellular carcinomas.But transarterial ehemoembolization is still an effective method of choice for this treatment.
