Hepatic artery pseudoaneurysm after liver transplantation: definitive treatment with a stent-graft after failed coil embolisation

Departments of ¹ Radiology, ² Abdominal Transplantation Surgery and ³ Hepatology, University Hospitals Gasthuisberg, Herestraat 49, B-3000 Leuven, Belgium

A 69-year-old woman presented with massive upper gastrointestinal bleeding owing to a ruptured hepatic pseudoaneurysm located at the surgical arterial anastomosis, 2 months after combined liver and kidney transplantation. Initially the pseudoaneurysm was successfully coiled but 3 weeks later recurrence of her symptoms occurred. Hepatic angiography revealed partial reperfusion of the coiled pseudoaneurysm; definitive treatment was performed by placement of an expanded-polytetrafluoroethylene (e-PTFE) covered coronary stent-graft, completely excluding the pseudoaneurysm. Radiological follow-up studies demonstrate a patent stent-graft functioning normally.
