title: Rupture of hepatocellular carcinoma after transcatheter arterial embolization: an unusual case.
abstract: Rupture of hepatocellular carcinoma (HCC) as a complication of transcatheter arterial embolization (TAE) is very rare. An unusual rupture of HCC after TAE was treated with successful surgical resection. A 65 year-old woman with liver cirrhosis developed multiple HCC in both lobes of the liver. TAE was attempted for the HCCs, but the original left hepatic artery, obliterated due to the previous repeated TAEs, was replaced by the left gastric artery. Right hepatic arteries were embolized while preserving the replaced left hepatic artery. Nine days after TAE, the patient presented a rupture of HCC in the left lateral segment of the liver, in which no deposit of Lipiodol was recognized. Since additional TAE to achieve hemostasis failed, left lateral segmentectomy was carried out with concern for the poor hepatic functional reserve. The patient was discharged 3 weeks after surgery without any complication. This is the first case of ruptured HCC in the non-embolized part of the liver after TAE, which was resected successfully.
