Shin et al reported a model predictive of liver abscess following transarterial chemoembolization of a hepatocellular carcinoma (HCC). The authors are from Changwon Fatima Hospital and Sungkyunkwan University in South Korea.
(3) type 1 biliary abnormality (biliary invasion by HCC, biliary stricture, extrinsic compression of the bile duct, common bile duct stone without complications)
(4) diabetes
(5) number of tumors
(6) tumor necrosis
(7) maximum tumor diameter in cm
(8) vessel (arterial) injury during embolization
(9) gelfoam embolization
