Segmental embolotherapy for hepatic cancer: Keys to success
Transcatheter chemoembolization using Lipiodol (Lp) mixed with chemotherapeutic agents followed by Gelfoam particle injection only to the tumor-bearing hepatic segment (segmental Lp transcatheter hepatic artery embolization) (TAE) was applied to more than 100 patients with hepatocellular carcinoma and metastatic liver cancer. For segmental Lp-TAE, knowledge of the variations of intrahepatic arterial anatomy is important. Furthermore, the catheters and guidewires, volume of Lp, kinds and dose of chemotherapy, preparation of the mixture of Lp and chemotherapy (Lp-emulsion), method of injection of Lp-emulsion and Gelfoam particles, as well as the follow-up computed tomography examination are key items to the success of the procedure and are reviewed.
