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.
肝内动脉假性动脉瘤是小儿肝移植后一种罕见的、危及生命的并发症。首选的治疗方法是介入放射学管理，对动脉瘤近端和远端的节段动脉进行血管内栓塞。然而，这种技术会导致动脉瘤远端的动脉灌注丧失以及亚段动脉缺血。
我们报告一例1岁女童在劈裂式肝移植后发生假性动脉瘤的病例。通过经皮直接经肝途径进入假性动脉瘤，随后将超选择性线圈置入动脉瘤内。
即使在肝移植后的小儿患者中，超选择性经皮经肝线圈置入也是可行的，并且能够保留肝动脉的全程。
