Abstract
BackgroundIntrahepatic arterial pseudoaneurysms are a rare, life-threatening complication after pediatric liver transplantation. Treatment of choice represents interventional radiological management with endovascular embolization of the segmental artery proximal and distal to the aneurysm. However, this technique results in loss of arterial perfusion distal to the aneurysm with subsegment arterial ischemia.Case presentationWe report a case of a 1-year-old girl with a pseudoaneurysm in the split-liver graft. Direct percutaneous, transhepatic access to the pseudoaneurysm was performed followed by super selective coil application into the aneurysm.ConclusionSuper selective percutaneous, transhepatic coil application is feasible even in pediatric patients after liver transplantation and results in preservation of the entire course of the liver artery.
Highlights
Pseudoaneurysms of the hepatic artery occur in 0.3– 2.6% of cases after liver transplantation (St Michel et al 2019)

Summary
Pseudoaneurysms of the hepatic artery occur in 0.3– 2.6% of cases after liver transplantation (St Michel et al 2019). They may either develop spontaneously in the early as well as the late postoperative period or as iatrogenic complication after interventional biliary procedures (St Michel et al 2019; Tessier et al 2003). Case presentation Living donor liver transplantation was performed with a left lateral split (Segment II / III) for biliary atresia at the age of 7 months. The parenchymal and biliary structures did not show any signs of ischemia
