Bile duct necrosis: complication of transcatheter hepatic arterial embolization.


Bile duct necrosis because of transcatheter hepatic arterial embolization (THAE) in two patients with hepatocellular carcinoma is reported. Preoperative THAE was performed on 29 patients, and bile duct necrosis was experienced by two of the 29 (7%). In these two patients, gelatin (Gelfoam) powder was used as the embolus. Among the 24 whose embolus was clear, four were embolized with gelatin powder. Therefore, incidence of bile duct necrosis after THAE with gelatin powder was 50%. Because of the hazards of severe complications such as bile duct necrosis, we conclude that gelatin powder should not be used except for the THAE of no more than one segment of the liver.
