Endovascular treatment of supra-celiac aortic pseudoaneurysms following liver transplantation.

The development of supra-celiac pseudoaneurysms following aorto-hepatic reconstruction during liver transplantation represents a major and surgically challenging complication. However, the use of endovascular stent grafts for the exclusion of aortic aneurysms is now a standard procedure with low morbidity and mortality. We demonstrate the successful endovascular repair of three cases of supra-celiac pseudoaneurysms, which developed after liver transplantation. A 40-yr-old woman, a 61-yr-old man, and a 45-yr-old woman underwent liver transplantation for end-stage liver disease. Between three months and five yr after the transplantation the patients developed large supra-celiac pseudoaneurysms leading to thrombosis of the hepatic artery and biliary complications. The stent graft implantation was uneventful, one endoleak Type I occluded spontaneously. There were no intervention-related complications. Unfortunately, one patient died one month after the procedure due to progressive liver failure and one died after five months due to multiple organ failure. One patient is still alive and in good condition.
