Abstract
A 74-year-old man exhibited obstructive jaundice and underwent PTBD at a nearby hospital. After he was admitted to our hospital, examinations revealed that the jaundice was caused by a hepatic artery aneurysm with its neck at the junction of the proper and common hepatic arteries. Since severe stenosis of the main portal vein was also found, there was a concern that embolization of hepatic artery could induce dearterialization and corresponding failure of the liver. Therefore, equipments for portal vein arterialization were also provided at the procedure. Transcatheter arterial embolization using steel coils were performed on the proper and common hepatic and proximal gastroduodenal arteries, which respectively were the vessels proximal and distal to the lesion. The procedure was successful with no post-op liver failure. The aneurysm was reduced and the biliary stenosis was relieved. So far as 15 months follow-up, the patient is showing favorable clinical course with no recurrence of the obstructive jaundice.
