    Abstract:
    BACKGROUND: Hepatic artery pseudoaneurysm is a rare but very morbid complication after liver transplant. Treatment options include ligation or endovascular embolization, followed by revascularization. We describe a new endovascular approach by stent exclusion in a high-risk patient. RESULTS: A 62-year-old male who received a second liver transplant after failed allograft presented with hemobilia and was diagnosed with a hepatic artery pseudoaneurysm in the setting of infection. Given his hostile abdomen, an endovascular approach was sought. We excluded the mycotic pseudoaneurysm with multiple covered stent grafts extending from the common hepatic artery to the right and left hepatic arteries. He was discharged with long-term antibiotics. On his 6-month follow-up visit, his stent was patent and hepatic function was stable. CONCLUSIONS: Endovascular stent-graft placement for management of hepatic artery pseudoaneurysm after liver transplant should be considered as a lower morbidity alternative to surgical repair, even in the setting of infection.
