•Case report.•Splenic artery steal syndrome can be a significant complication after liver transplant.•Splenic artery steal syndrome after liver transplant can be managed by splenic artery embolization. Split liver transplant is gaining increasing use in the current environment of growing organ shortage. It is associated with a higher risk of complications, owing to its complexity and technical challenges. Splenic artery steal syndrome, is a complication that can occur following liver transplant and cause inadequate hepatic arterial inflow, hepatic artery thrombosis and graft loss. We report a successful management of hepatic artery thrombosis and splenic artery steal syndrome after a split liver transplant by surgical thrombectomy followed by angiography and splenic artery embolization. 60-year old female, with liver cirrhosis, who underwent a deceased donor right lobe orthotopic liver transplant. The procedure was complicated by hepatic artery thrombosis, requiring re-exploration. However, despite anastomotic revision the patient had poor hepatic arterial inflow. Both angiography and ultrasonography demonstrated splenic artery steal syndrome. This was successfully managed by splenic artery embolization with improved hepatic artery flow on ultrasonography and angiography. Splenic artery steal syndrome is a rare complication that can occur after a liver transplant. Experience with this phenomenon is limited in split liver transplantation.We demonstrated successful early management of splenic artery steal syndrome with coil embolization in a split liver transplant preventing further morbidity and graft loss.
