To evaluate the usefulness of transcatheter arterial embolization (TAE) through the omental branch in the treatment of hepatocellular carcinoma (HCC) with blood supply from the omental branch. Fifteen patients with HCC fed by the omental branch underwent TAE. All but one had previously undergone several therapies for HCC, including TAE. Three patients had intraperitoneal hemorrhage caused by ruptured HCC fed by the omental branch, and two necessitated emergency TAE. The technical success rate, therapeutic effect, and safety of TAE via the omental branch were evaluated. Twenty-six omental branches that fed HCC were observed angiographically. Attenuation or occlusion of the hepatic artery was observed in 80%. Nineteen omental branches (73%) could be successfully embolized. Hepatic hemostasis was achieved in all patients with ruptured HCC. Tumor recurred in 80% of patients who underwent successful TAE of the omental branch, and additional therapy was performed in six patients. Ten patients died after 2-26 months (mean, 8 mo). Five patients were alive for 3-13 months (mean, 7 mo). Severe complications were not observed in any patient. TAE of the omental branch is safe and has become technically feasible in almost all patients, but ...Continue Reading
