Intrahepatic 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. We 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. Super 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.

小儿肝移植后肝内假性动脉瘤的超选择性经皮经肝线圈栓塞术：一例报告

小儿肝移植后，肝内动脉假性动脉瘤是一种罕见的威胁生命的并发症。选择的治疗方法是通过对动脉瘤近端和远端的节段动脉进行血管内栓塞来进行介入放射治疗。但是，该技术导致动脉瘤远端的动脉灌注减少，并伴有节段性动脉缺血。我们报道了一个1岁女孩在肝分割移植中有假性动脉瘤的病例。直接经皮经肝进入假性动脉瘤，然后将超选择性线圈应用于动脉瘤。即使在肝移植后的小儿患者中，超选择性经皮经肝线圈的应用也是可行的，并且可以保护整个肝动脉。
