Pseudoaneurysm of the radial branch of the splenic artery with pancreatic pseudocyst in a child with recurrent acute pancreatitis: treatment with endovascular stent graft and cystogastrostomy

Splenic artery pseudoaneurysms (SAPs) are rare in children and usually follow abdominal trauma. Although pancreatitis is a well-known cause for SAP in adults, pancreatitis resulting in SAP has only sporadically been reported in children. Before the refinements of endovascular techniques for management of SAP, surgery used to be the mainstay of treatment, often resulting in splenectomy. Recent technical advancements, including development of smaller delivery systems and microcatheters, have made endovascular treatment feasible in children with SAP and increased chances of splenic preservation. In this article, we report a rare case of SAP associated with a pancreatic pseudocyst in a 5-year-old boy with recurrent acute pancreatitis that was managed by endovascular stent graft and cystogastrostomy.
