title: Multidetector CT-guided endovascular treatment of a splenic artery aneurysm in a child with split-liver transplant and surgically ligated splenic artery origin.
abstract: We report the case of a child who underwent left lateral split-liver transplantation for biliary atresia and surgical ligation of the origin of the splenic artery at the time of the transplantation. Post-transplant portal vein thrombosis was initially treated with a meso-rex shunt. This shunt subsequently thrombosed and was replaced by a splenorenal shunt. Three months after splenorenal shunt placement, US showed a 3.7-cm pseudoaneurysm at the hilum of the spleen. Multidetector CT with 3-D reconstruction allowed precise identification of the pseudoaneurysm feeding artery and therefore helped in planning the interventional radiology procedure, avoiding explorative selective catheterisation. The pseudoaneurysm was successfully treated with endovascular coil embolisation.
