|
Hepatic artery complications after liver transplantation include hepatic artery thrombosis, stenosis, pseudoaneurysm (PA), and others. Among these complications, hepatic artery PA is reported to have a low incidence, but it is associated with a devastating and often fatal outcome and a high risk of rupture. Herein, we present the case of a 56-year-old male patient who underwent living-donor liver transplantation because of alcoholic liver cirrhosis. A silent PA of the hepatic artery proper was detected incidentally on computed tomography scan during routine follow-up 15 days after surgery, and was successfully excluded by implantation of a coronary balloon-expandable stent-graft using ‘conical remodeling’ by two-step ballooning. This technique can be effectively used for PA of visceral arteries with tapering-small diameter, in which flow preservation is critical to patient care.
