Transcatheter arterial embolization for spontaneous rupture of hepatocellular carcinoma.

For the last 6 yr, we had 47 cases of spontaneous rupture of hepatocellular carcinoma causing hemorrhage into the peritoneal cavity. Thirty-three cases were treated by supportive care and 14 cases by emergency transcatheter arterial embolization. Fourteen cases underwent emergency transcatheter arterial embolization and abdominal pain developed in 71.4%, shock in 50.0% and bloody ascites in all cases and the hematocrit of bloody ascites ranged between 1.0% and 40%. On hepatic angiogram, the mean tumor extent rate was 47.9% and the extravasation of the contrast material was noted in 35.7%. The mean survival time of 14 cases that underwent emergency transcatheter arterial embolization was 98.5 days and 13.0 days in 33 cases with supportive care. The former was significantly longer than the latter.
